• 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.

• Satellite M30-106: USB Ports not working not

  Hello.

  I have a problem with my Satellite M30-106. One day, the system froze (Windows XP with SP2) during the passage of the machine off. I was forced to keep the button "power" for a while in order to close the system. However, since all 3 USB ports do not work.

  The system does not recognize the "" them. I can't see in Device Manager. I tried to reinstall the system, but it did not help.

  Can someone help me, pelase =)

  Hello

  It looks like a hardware problem. At whatever it is connected to the USB ports at the time? Could you check the USB ports visually and see if they are damaged or wobbly. It is a bit of a long shot, but you may have a short circuit decision and which could disable the USB.
  If the motherboard is damaged then outside fixing/replace your only option would be a PCMCIA USB card, they are not expensive.

• 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.

  Hello

  You won't lose me. I'm probably in a different time zone you are.  I live in Europe.

  If you still have the unknown device follow these steps:

  Open Windows Explorer and locate the SWSetup folder.

  Expand the folder, find the sp56724 folder and double-click it to open it.

  This is where the driver for the device unknown (USB 3.0 host controller should be).

  Call the Device Manager.

  Right click on the unknown device and select Update driver software.

  In the next window, select browser my computer for driver software.

  Now, you can choose to let the operating system locate the software or the path to the sp56724 folder yourself. In both cases, ensure that a signed driver is selected.

• External USB HDD cable does not match of Satellite A200 USB ports

  I bought a new Notebook from Toshiba A200 Satellite and a 500 GB Maxtor One Touch 4 500 GB hard drive.
  The end of the USB cable to the HARD drive does not match one of the ports on the Toshiba.

  Can I get an adapter, or try to find a rope?
  HARD drive uses USB 1.1, 2.0 or Firewire port.

  Thank you!

  What?

  Sorry, but I don't believe that.
  The Satellite A200 supports USB 2.0 ports Commons and it should be possible to connect a normal USB cable to the laptop!

  Are you sure you are using the right cable to 100%?

  It should looks like this:

• Satellite P850 - 12Z USB 3.0 Ports right side do not work USB 3.0 speed

  Hi all

  I bought a portable Satellite P850-12Z with * 4 * USB 3.0 ports. Two ports on the left side and two ports on the right side with sleep functions and fresh.

  If I connect an external drive Verbatim USB 3.0 ports on the left side, everything works fine. Transfer rate is about 70-90 MB/s, but if I connect the * same drive * USB ports on the right side I see the pop up message "this device can perform faster if you connect it to a Super Speed USB 3.0 port" and the transfer rate is about 20-30 MB/s. These ports operate as USB 2.0 ports.

  I repeat that all the available ports on the laptop are USB 3.0.

  Anyone know what is happening with ports USB 3.0 on the right side?

  I don't have another USB 3.0 drive to do more tests.

  Thank you

  Carlos

  > I repeat that all the available ports on the laptop are USB 3.0.
  You are absolutely right.
  I ve checked specification s notebook, and all ports are USB 3.0 ports.

  It is not easy to say what the problem is here.
  What you can do is to contact the nearest Toshiba service provider and ask for explanations.
  They know what the problem is here.

  Maybe a few update driver or BIOS update offered in the future will solve this problem. In my opinion, you should continue to use the ports on the left side for data transfer.

  Hi François,

  Your model has USB ports 1.0 and if the old USB drive works but other USB devices are not that what would they need to a USB 2.0 port. The basis of xb3000 will support your DV8-1093 in terms of power.

• Nighthawk R8500, USB 3.0 Flash drive not recognized USB 3.0 Port, Port of only 2.0

  My Nighthawk R8500 router with the latest firmware, V1.0.2.54_1.0.56, does not recognize my SanDisk Ultra Fit 128 GB USB 3.0 Flash drive when it is connected to the router USB 3.0 Port. The Ultra Fit is formatted in FAT32 and works fine when plugged into USB Port 2.0 router or my laptop.

  At first, I thought maybe USB 3.0 Port on my router wasn't working at all, but it recognizes my SanDisk 16 GB Cruzer USB 2.0 Flash Drive that is also formatted FAT 32. Unfortunately both my laptop have USB 2.0 Ports, so I don't know if the problem is with the router or the Ultra Fit Flash Drive. Everyone knows about this problem of their Flash 3.0 player is not recognized in USB 3.0 Port their router, especially with a SanDisk Ultra Fit? This problem can be resolved through firmware? I'd really like to take full advantage of the speed of USB 3.0 as I like to share files through my router via ReadyShare and ReadyCloud.

  Thanks in advance for any help, Carlos

  Technical support with me. Installation of a updated firmware, V1.0.2.64_1.0.62, which became available shortly after my post, solved the problem. -Carlos
