• HP DV7 ENVY: USB 2.0 Port does not

  Hello

  I have a DV7 HP ENVY with 3 - USB 3.0 ports and 1 - USB 2.0 port. The USB 3.0 ports are working well but USB 2.0 does not work. When you plug a USB stick to the USB 2.0 port power led on the memory stick lights up but the led data is not. The computer does not at all to the inserted USB memory. The USB works fine in other 3.0 ports. I tried also to connect other USB devices, and it's the same thing. They work well on USB 3.0 ports, but nothing happens when you connect to a USB 2.0 port.

  I was looking at the USB drivers in Device Manager and haven't noticed anything that seems strange.

  I have run the system test diagnostic USB to start the system and got the following codes:

  Failure ID: 9BXQGK-6JK858-QFPK0K-8D0G03

  Product ID: C1W26EA #UUW

  No idea if this is a hardware or software failure?

• USB 3.0 Ports does not not on HP Pavilion dv7-6102sa

  Some time ago I did a complete reinstall of Windows 7 on my laptop, remove Windows 7 Home Premium that accompanies it and installing a fresh Windows 7 Home Premium.

  I had to install some drivers and updates, like you do and then found what I wanted to work, worked.
  
  Except the USB 3.0 ports.

  When I plug my USB 3.0 on a USB 3.0 flash drive, the access light flashes and then stops. But the operating system does not recognize and does not normal "du-DUM!" sound.

  In Device Manager , I see three other devices: Controller of Bus SMand two instances of the (USB) Universal Serial Bus controller. Clicking on software driver update , then "Automatically search for an updated driver" on both of these entries translates into a "Windows failed to install your controller (USB) Universal Serial Bus".

  My computer was purchased new in 2011.

  Any help would be greatly appreciated.

• Connection and configuration USB-485/2 2 son loopback

  I use the NI USB-485/2 with CVI box and managed to configure the ports of two 485 in mode 4 son, connects the ports for the Loopback tests and tested by sending data a port and reception of the same data in the second.  Now I want to change the configuration 2-wire because I need to interface with equipment using 2 son so I could read on all the documents that I can find and still have confusion on the port configuration of 2-wire control and transceiver loopback connections.  I see three options of port configuration of 2-wire) 1 DTR controlled with echo, 2) DTR controlled without echo, TXRDY 3) controlled car.  I see the 'RS-485 Transceiver Control' table in the manual and quick reference but don't understand what he's trying to tell me at all.  I studied it for a long time.  There is no explanation of these three options.  So my question is what are the differences in these three and for each of these options how the port must be configured (any active Protocol communication?) and how would wire the 2 ports together to run a loopback test?

  I have port configurations installation via attributes VISA for Auto 2 son with baud, num bits, stop bit, etc., and seems back successful responses.  (I used VISA only because I have not found the ComSetEscape call until I finished the above).  I connected bore - portB TX - TX and portA TX + portB TX + for the loopback test and couldn't get it to work in the short time that I tested.  It seems that the data passes but never gets received.  I use the VISA entry and read functions.

  Tom, this paper addresses a bit more on the different modes: http://digital.ni.com/public.nsf/allkb/E905D94CF3C0601D862565EF004D5D7F . In addition, we have several examples and walk through on the way to a 2-wire loopback test using 485. Have you tried to use one of these examples?

• Envy 17-j141na: a USB 3.0 port only works on USB 2.0

  Hello

  I have a HP Envy 17-j141na (product number: J0C16EA #ABU) running Windows 8.1.  I recently tried to connect a Sata hard drive via a USB 3.0 enclosure and found that the right rear USB port works with a USB 2.0 cable and any USB 3.0.  There is no problem with any of the three other no ports just this one.  Grateful for any help.

  Thank you.

  Hello Malygris1,

  Thank you for your help and suggestions.  I investigated further and found that the problem had become a problem on the port adjacent to the original track and then there are two with the same problem.  I was struggling to believe I had lost a second port and so took risks on the purchase of an another leader of a different even if manufacturer initial lead was again with the Cabinet.  The result was successful with all USB 3.0 ports.  I can only assume that there was a faulty connection in original mind that failed when it was routed to one side of the laptop and not the other.  Thanks again, I'm certainly glad that the fault was not in the computer.

• "This USB mass storage device can transfer information faster if you connect it to a USB 3.0 port Superspeed ' when the device is already connected to a USB 3.0 port.

  I just bought and installed a USB 3.0 card. It is the Startech PEXUSB3S2 PCIe card. I installed the card in a PCIe 2.0 X 1 slot. The manual says it's exactly the slot, that it supports.

  The Manager device displays NEC Electronics USB 3.0 Host Controller and NEC Electronics USB 3.0 Root Hub are installed and are working correctly. I have a Thermaltake BLACX5G 5 G USB 3.0 hard drive caddy. The transfer rate is only 35 MB/s using the HDTune benchmark. It is a USB 2.0 speed.

  When the player is turned on, windows displays the message "this USB mass storage device can transfer information faster if you connect it to a Super speed USB 3.0 port»

  For some reason, the system doesn't see the caddy to drive USB 3.0 as being plugged into a USB 3.0 port, when it actually is.

  I remember having this same problem with Windows XP, when I bought a USB 2.0 card. The only thing that fixed it at the time was upgraded to XP SP2.

  This should not be a problem because I know that Windows 7 pro 64-bit supports USB 3.0.

  My motherboard is an ASUS P5QL-EM support an Intel Core 2 Quad and 4 GB of DDR2 memory. According to the manual owner the PCIe x 1 slots support architecture 1.0 and 2.0.

  Edit: I just tested the external hard drive and expansion card USB 3.0 on my motherboard Gigabyte of friends running Windows XP. Everything worked perfectly, no problems at all.

  Here, there is a problem with Windows 7 or the motherboard. Still unresolved, currently installs a floppy drive so I can update the firmware of my motherboard.

  I checked the implementation of the card several times, removed and installed in another motherboard to test, then removed and reinstalled again in my motherboard ASUS check several times for a fit course.  It still does not work. I have just completed update the firmware of the motherboard with the latest version, and I also did a new install of Windows 7, install the drivers USB 3.0 immediately after installing Windows over. None of this solves the problem.

  I'm running out of ideas on how to fix this without doing something drastic as a replacement for my motherboard. I don't want the speed of USB 3.0, but I don't think I'm ready for an another two or three hundred dollars to get it.

  I've been all over the ' net trying to find a solution and read tons about USB USB 3.0 specifically and in general. I can find no reason why the drivers would install and report that they are working correctly, but fail to connect to 3.0 speeds. I think that this would generate a certain type of error instead of such a strange symptom.

  EDIT:

  Here go us. I knew that is was a bad idea to buy one main (ASUS P5QL-EM) card that had to be overclocked to 1066 MHz for DRAM memory. I did all this work, and every time I reset my BIOS or updated it would always be the frequency DRAM back to where it should be (1066). After a reset of the computer was the starter and I just let it start instead of setting the DRAM frequency and, suddenly, USB 3.0 card worked perfectly. I confirmed this by setting the frequency to 1066 and looking at the USB 3.0 card fail again. I guess it must have something to do with the clock being sent to the PCIe bus.

  In any case, the USB 3.0 card works perfectly and gives me a transfer rate HD Tune to 99 MB/s on a drive from WD SATA 7200 RPM and 86.1 Mbps on a Samsung drive hard 5400 RPM / MIN 3,5 "SATA. These are the same reference points I get when these drives are connected to my internal SATA connectors. I'd say USB 3.o works perfectly now and maxing out the hard drives performance.

  Thanks for any help.

• Windows has stopped this device because it has reported problems. (Code 43) A request for the USB device descriptor has failed.

  Separated from this thread.

  Hello

  I'm faced with the same question. I went to settings of your laptop and ran the recovery, but it did not help. I went to Device Manager and I noticed an error: Windows has stopped this device because it has reported problems. (Code 43) A request for the USB device descriptor has failed. Tried to fix that with an alternative of Microsoft Community (http://support.microsoft.com/mats/hardware_device_problems/?wa=wsignin1.0), but the issue could not be resolved. I don't know if they are related, but I think so. Spent so much time trying to solve this problem and would be really grateful for the help. Have had the computer for less than 3 weeks...

  Hi Ewa,

  Thanks for the reply.

  I suggest you to update the drivers for the chipset of your computer and check if it helps. You can use the link below. Select the appropriate component and the operating system from the list. The link given below is for Lenovo 11 2 yoga, if you have any other device then please provide us with the exact model number or select the correct model number.

  As you mentioned that the other two USB ports work correctly, according to me is not a problem with the driver. It seems to be a hardware problem.

  Let us know the status.

• Tecra R840-10 t has no work webcam or USB 3.0 port

  Even if this [another thread | http://forums.computers.toshiba-europe.com/forums/thread.jspa?threadID=62061&start=15&tstart=0] has been marked as resolved, the problems remain, but are not related to the bone, hw-partners.

  1 week after that I got a Tecra R840-10 t (PT429E-00M007EP) of Windows 7 have frozen at startup and the fan run at maximum speed. All I could do was to enter safe mode. After a factory reset (reinstalling OS of the hidden HD partition), not even the safe mode worked!
  Took back to the store, 2 days later a local Toshiba representative referred to the store as fixed (they have updated the BIOS...)

  2-3 weeks later, same problem. I called Toshiba directly, they have picked up the laptop, took almost 2 weeks and sending parts of the Germany twice before they sent it. I had to call them to find out they were going to deliver the next day. So far it seems to be fixed, Windows has not frozen since.

  However, now, little more than a month after I bought this laptop from professional quality, I noticed that, on his return, the USB 3.0 port (as long as this port) and the webcam does not work. They do not appear in the Device Manager, update their drivers through page for the download of Tecra yields nothing (and you have to go through hoops to actually install the webcam driver), nothing. It's as if they did not exist. I guess that any material they brought in wasn't exactly in perfect condition, or someone forgot to plug it into some pine trees.

  I tried several Linux LiveCD as well, they all recognize the material to varying degrees (being the most comprehensive Debian), but no recognize the USB 3.0 port or the webcam as well.

  Not an OS problem. Call them once again, waiting for a response from a representative Monday morning. Seriously considering to move directly to a repair center and asking the complaints book. There is no guarantee that this laptop won't break again.

  Not a happy camper.

• External Toshiba HARD drive not recognized on USB 2.0 ports, but only on USB 3.0

  Hello

  I have a Toshiba drive external HARD 750 GB USB2.0/USB3.0
  Now, this HARD drive is not recognized on USB 2.0 ports from my laptop (same thing on my desktop computer) but only on the USB 3.0 port.

  I have try on port USB2.0 computers different (desktop, laptop) but it doesn't work. The LED is the lightning, but the drive does not appear in the file Explorer.

  You have any ideas?

  Thank you

  > Now this HARD drive is not recognized on USB 2.0 ports from my laptop (same thing on my desktop computer) but only on the USB 3.0 port

  USB 3.0 port 900mA feeds. The USB 2.0 port common provides 500mA.
  I think that the HARD drive needs more 500mA power in order to work properly.

  So if you want to use the HARD drive on USB 2.0 ports, I recommend you to use a USB Y cable which allows to connect the HARD drive to two USB 2.0 ports

• External USB 3.0 HARD drive does not work on USB 3.0 port

  Hello guys,.

  I have a problem with my external HARD drive and the problem is that it is USB 3.0 feature does not work in my computer.

  The curious thing is that it works very well in the SATA port or a normal USB 2.0 port.

  Y at - it a failure with the HARD drive or is there something wrong with my motherboard (M5A99 fx pro r2.0)?

  Thanks in advance.

  From my point of view of the few is not HARD drive problem because the HARD drive operates in a USB 2.0 port.

  I m wondering if you tried to update the USB 3.0 driver.
  Have you tried this HARD disk in another computer / USB 3.0 ports?
  I think that its worth a check.

  Also, I read on some problems of USB 3.0 controller from different manufacturers.
  Sometimes, it might be possible that some problems of compatibility between different devices may arise.

• Toshiba Store Art 4 USB 3.0 1 TB works not with USB3.0 or USB 2.0 port

  Hello
  I have a big problem with my external hard drive and I hope someone can help me.

  Here's the thing:

  I used my external drive only on computers that don't have any port usb 3 and all worked well. The drive has been used only with usb ports 2.

  Now, I got a computer with a usb port 3 and I was happy to be able to use my external hard drive at full speed.
  Has been fine until I wanted to transfer a file using my drive.

  The disc has been recognized either of usb ports 2. The NTFS partition is a partition BRUTE! I had to ' chkdisk/f G:' to make it work again on my usb ports 2. And some files were missing!

  Then, back on my other computer (usb port 3), the contents were not the same! I mean some of the files that I deleted when it is plugged into usb 2 returned when plugged usb ion 3! And then, back to the usb 2, partition became RAW and I had ' chkdisk/f G:'... once again!

  So, to make it as simple as possible, after some testing, it seems that the drive can only be used on the usb ports 2-only on ports usb 3 but can not be used at a time, which is very annoying for a portable external hard drive.

  I tried to format the drive to my usb port 2 and return on the usb port 3, the content came as if I had never formatted it and then back on the usb port 2, the RAW score again...

  I use Windows 7 and 8.1 Windows computers.

  Someone at - it experience that? What is the drive (Toshiba Store Art 1 TB USB3 4)? What is the USB 3 specification? Is - Windows 7 or 8.1 drivers?
  And above all: what can I do?

  Thank you very much!

  This external plug & play Toshiba HDD supports two USB standards: USB 3.0 and USB 2.0
  HARD drive around needs bus power 900mA to work correctly.

  The USB 3.0 port supports this standard 900mA. The USB 2.0 port allows only to 500mA.
  If in case the HARD disk is not working properly connected to the USB 2.0 port, I recommend you to use a USB cable to Y in order to connect the 2 ports USB 2.0 HARD disk.

  I have no idea why the content on the HARD drive is different, but from my point of few of the USB standard does not affect content.

  In my opinion, the HARD drive wasn't working properly using a USB 2.0 due to the low power.

  By the way: this HARD drive supports some additional features like the ability to oversight function and monitor to alert of the disk space that sends a alert when there is not enough available storage space.

  For advanced users, Toshiba has added the ability to customize the backup routine, including the ability to select only the most common file types for backup and change how many times a backup takes place.

• EliteBook 8470p: EliteBook 8470p USB 3.0 ports driver not installed in Window 7 Ultimate 32 bit

  Dear Sir.

  I am facing problem in installing driver for USB 3.0 in EliteBook 8470p on Windows 7 Ultimate 32 Bit Port. So please say if 32-bit is taken in charge or 64-bit supported for USB 3.0 driver.

  its two USB 3.0 ports doesn't detect the USB 2.0/USB 3.0 or USB key (Flash DRIVE, portable, etc.)

  Please answer soon

  Hello:

  The usb controller you model posted ID indicates that your laptop is not a p 8470, but a p 8460.

  You need this driver usb 3 to this ID.

  FTP://ftp.HP.com/pub/SoftPaq/sp54501-55000/sp54511.exe

  The 8470p have the Intel USB3 controller and the 8460 p have the Renesas Electronics USB 3.0 Host Controller.

  That's why I finally asked for hardware ID, because if you had a 8470 p then or the other of these Intel drivers I posted should have worked.

• Vodacom k3772-Z not detected on Satellite L755 USB 3.0 port

  Good day to all,

  I kinda a strange problem, the company that I work received point on the toshiba Satellite L755 PSK2YE and a box of vodacom K3772-Z modems for distribution to our customers.

  We picked up that these modems are not detected at all when plugged in the port of USB3 laptops left side (we tried 3 modems on machine Ong 3 with the same result each time)

  Modems work perfectly well when it is connected to the usb ports on right 2 and all the rest that we connected to works of 3 usb port very well including older models of modems.

  I also tested the modem on another machine of 3 USB (also using the usb controller 3 renesas) and it works beautifully.

  I have notcied that if you disable the usb controller 3 on the laptop and turn it back on with the stick of 3 g connected to the unit is detected correctly however if you unplug in and try again once it does detect it yet.

  It's using the latest drivers and firmware.

  I tried to find a solution online but had no chance.

  Any ideas what could be the cause?

  > Modems work perfectly well when it is connected to the usb ports on right 2 and all the rest that we connected to works of 3 usb port very well including older models of modems.

  From my point of view it would mean for computer laptop USB 3.0 port works correctly and, possibly, there is a compatibility problem between the modem and the USB 3.0 port. Maybe you should contact check the modem manufacturer support page for more information

  I read on some forums that many people had problems to install this modem using Win 7 64 bit with 32-bit system was not a problem, someone used the drivers released for modem K4505.
