• Satellite P10-304: USB Ports not recognize anything

  I have a Satellite P10-304 and the USB ports not recognize anything that are attached to them. Device Manager tells me that they are enbaled and works correctly. What can be wrong with them or what can I do?

  Hello

  One of my friends has the same unit on the work and everything works perfectly. It uses the USB hub too and have many external devices connected to the unit.

  By the way: something like who can occur if the external device is not removed correctly use safely remove hardware option. If you try to connect any other device after that in most cases it is not recognized at all. In this case, you can restart the device or remove ports from the Device Manager and use the hardware detection to find them again.

  Good bye

• Dynadock USB Ports not working not

  I have a Toshiba Dynadock (unfortunately I do not know the model number I can't). It is less than a year and has two USB ports in the front, with 2 Sockets (I guess that one of the earphones and a microphone), has 4 ports usb at the back and probably a DVI/HDMI port as well.

  The problem is that none of the USB ports work on it, you plug a USB device into one of the ports and Windows 7 does not detect something that is attached. It was working fine until recently, and then the printer started to play up by printing only a few lines in a document that you asked to print, and then after that nothing worked (I don't think that the printer is at the origin).

  When I reassembled the eject button on the dock, Windows recongonises ejection and hot flashes with the software Dynadock saying "Dynadock has been ejected" or similar.

  The computer is a Toshiba. I reinstalled the drivers, made a restore to a date when I heard he was working and have restarted the dock, but nothing worked so far. Any suggestion would be appreciated.

  Thank you

• Satellite C50 - B - 14 d - USB ports not working not

  I have a C50 Satellite - B - 14 d and had again for about 4 months.

  I didn't know that at the time of the purchase (online) that there is no optical drive, so I bought an external.

  Trying to plug into it, discovered that nothing happened in the 2 ports on the right side (2.0 and 3.0) so I decided to try the left port 2.0.

  It does not detect the device, but it undetects then within 10 seconds, it continues to do this every few seconds it is impossible for me to access my work on CD!

  I contacted the people I bought it since then, but they say it's a matter of Toshiba?
  Can someone help to solve what I don't want to send it for repair because I can't be without him more than 2 days.

  HHHEEEEELLLLPPPPPPP!

  I put t he thinks that the s notebook issue if all the USB ports work in relation to other devices USB; That is to say the USB mouse.

  From my point of view of a few external USB CD/DVD drive could not be recognized because of the low power of the USB.

  Try to connect the CD/DVD drive to the laptop using the USB Y cable which allows to connect to two USB ports.

• IdeaPad S510p 3 USB ports not working not

  Recently, I bought a Lenovo IdeaPad S510p with BACK installed in it.

  No, it didn't solve the problem.

  I have to install Windows 8.1, and then everything worked fine.

• Comm port not detected by VISA / MAX after the device power cycle connected

  I have a device communicating via USB virtual comm port. The device and labview program both work very well, most of the time. The program is designed for the automatic connection for the connected equipment. It works perfectly when I unplug and reconnect the USB cable.

  However, if the unit power cycled as the USB cable is connected and the program/vi is running of things go wrong. The device enters a phase of boot loader for a few seconds to the power upward, if labview tries to query the port comm during this phase the comm port is corrupted in some way and is no longer recognized by VISA / NI MAX. However, other programs, hyperterminal, etc device manager can see and communicate with the port when the boot loader is complete. For Labview / NI MAX to see the port I have to physically disconnect the USB cable. The program does not need to be restarted in order to detect the port comm again and, infact, labview is restarted or my compiled program does not solve the problem. Physically disconnect the USB port allows visa / MAX OR see the port is connected.

  It seems to me that there is a problem with VISA where somehow if a device is not correctly identified by VISA during the first attempt it just does not take into account the port until a physical intervention. Is there a way to force VISA to reassess completely all connected comm ports?

  Hello MJanus,

  As far as I know, most of the virtual com ports are not fully supported by VISA so some quirks in its operation are to be expected: http://digital.ni.com/public.nsf/allkb/6E1922B526572CB8862571AA00544057?OpenDocument

  Officially, we do not support the use of com virtual ports, if unfortunately, the feature you have now is probably as good you'll be able to get with this configuration. I know it's not the answer you were hoping to hear and I apologize for the inconvenience, but it is not really possible visa work well with all software virtual com port due to the wide variety of products available.

  Kind regards

• USB mouse not detected at startup.

  Hello

  My new HP USB mouse is not detected when I start my PC. I have to unplug & plug to make it work every time. My USB ports are fine and my previous USB mouse still works fine. I deleted installation driver from the Device Manager, but no utility.

  I have Windows XP.

  No idea how to solve this problem?

  Shaan-

  HiShaan,

  I suggest you contact the manufacturer of the computer and check if USB devices is enabled in the BIOS and enable it and check if the USB mouse is detected when you start the computer.

  NOTE: Changing the BIOS / semiconductor (CMOS) to complementary metal oxide settings can cause serious problems that may prevent your computer from starting properly. Microsoft cannot guarantee that problems resulting from configuration can resolved BIOS/CMOS settings. Changes to settings are at your own risk.

  You can also check if the Interface device access human service is set to automatic and started. You can change it accordingly and check if it helps. To do this follow the steps below:

  1. Click Start and click Run.
  2. In the Run dialog box, type services.msc and click Ok.
  3. In the services window, scroll down to Human Interface device.
  4. ClickHuman double Interface of device service and click the general tab.
  5. Change the startup to automatic type, then click on apply.
  6. Click Start, and then click OK.

  Restart the computer and check if the USB mouse works fine when the windows start.

  I hope this helps. Let us know the result.

  Thank you and best regards,

• USB connection not detected for Samsung Fascinate

  I have a smart phone Samsung Fascinate 1500.  When I connect it by USB to my computer, the computer no longer detects it as a media device or mass storage mode (although it worked fine the first few times).  The phone also does not detect the connection and simply seeks to charge the battery.  I downloaded the latest drivers and tried allowing pop ups without success.  Any ideas?  I cannot download my music, and it's a lot of time to transfer photos by other means..., including that I had to buy a SD card adapter.

  The USB port works with other devices.  I don't think that the USB cord to my phone is the problem, as others have shared this problem in other forums.  Does anyone have a solution?

  Hi Lin,

  1. have you tried to connect the phone to another computer?

  2. have you made any recent changes of hardware software on the computer?

  Test the device on another computer. Additionally, make sure that the software provided with the Samsung phone is updated.

• USB PORTS NOT EXTERNAL SENSORS

  I have 3 usb ports on my laptop HP Clubhouse.  Have never encountered a problem like this in the past.  I can use my external mouse, USB port will not read a flash drive or an external hard drive.  I checked the Device Manager and there is no error message, and all USB ports are read as working properly.  I installed all the news updates and drivers and still nothing.  I could understand if I was to receive error messages which is however not the case.  Is it possible that all 3 of my USB ports would die at once, and if so, why all this bed as usual.  Help, please!

• Pavilion dv7-4177nr: dv7-4177nr right usb ports not working not

  So I recently bought a used dv7-4177nr, got home, and since it has been used, naturally the first thing I do is restore the system to factory conditions. I don't check the ports for a feature beforehand. Run all Windows updates, get rid of the bloatware and realized, "it would be easier with my mouse wireless." Go to plug in, and the ports on the right do not recognize. No sound of "you hooked something up" or looking for drivers or anything like that. Those on the left are working fine. Windows detects that there is no ports.

  I tried the things:

  Update the BIOS

  chipset drivers of the series AMD 8 (not completely sure that those who have the right ones, but nothing else has blown up or whatever it is)

  Remove the USB drivers from Device Manager and let Windows RE-add-the

  

  The left USB ports are directly on the motherboard and the ports on the right side

  on a removable daughter card.
