    Usb device is not recognized it has malfunctioned

  • mouly Jul 14, 2008

    I get the following message after connecting the SANSA EXPRESS to my PC. "USB Device Not Recognized. One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it. For assistance in solving this problem, click this message." (But of course, clicking the message only tells you that it's an unknown device.)

    I tried with two more PC’s but it showing the same error msg.

    Please assist me, waiting for your sincere reply.

    If you have more that 1 usb port on your computer.. some are lower speeds than others. What ever you are tring to move to are from your computer may take a faster speed port..

Msg which i get :- one of the usb devices attached to this computer has malfunctioned and windows does not recognize it. try reconecting the device. if windows still does not recognize it, replace the...

In most cases this message is fairly true and accurate. Whatever it is that you plugged in is most likely broken. Two things you can try to test this: 1. Plug it into another USB port in your computer, if it is the same message, move to step 2. If it works, then there may be something wrong with that USB port on the computer. 2. Try the device on another computer. If you get the same message, the device is probably broken. If it works, then most likely there is something wrong with the USB ports on your computer. Let me know if you need more assistance.

Usb ports not recognized

Did this suddenly start to occur? Were they working before? If so, it is very simple - shut down computer, remove the battery and unplug any power source, wait a couple of minutes and reassemble and power up. Wala! I read all kinds of complicated instructions, started with the simple, and problem solved.

GE Wireless "Malfunction" "Unknown Device"

Does the mouse and/or keyboard have a "connect" button on the bottom of either? Try restarting your PC, then, if you have installed new batteries, and the mouse/keyboard is still not connected, try the "Connect" button if any.

My archos 605 [160gb ] not recognized on my PC

I recommend trying your archos on a different computer just to see if it is a pc or archos problem. Your pc should come right up and ask if you want to charge or use the usb port or both. Try another computer.

Usb not recognised

Hello ak1979 ...

1. You're plugging in your Transend USB flash drive to your computer's USB port (as you've done many times successfully before with this SAME flash drive)?

2. It says "windows not recognise usb drive due to malfunction"?
a. Is that EXECTLY what the error says?
b. Is "it" an error dialog (window that pops up), or an error message from your Windows Event error logs? If a dialog, are there any pertinent error message entries in your Windows Event (System) log [Start > Run > type "eventvwr.msc" (without quotes), then "OK"]?

Try a bit of deductive troubleshooting:
  1. Restart (Reboot) your system [for a fresh start, if you will].
  2. Try plugging in your USB flash drive again, but in a DIFFERENT USB port.
  3. Try plugging in ANY OTHER "known good" USB device into the same USB port(s) used thus far that failed.
NOTE: If you EVER get any indication Windows recognizes the flash drive (like no error msg, or it shows in "My Computer"), IMMEDIATELY perform a "Check Disk" on it:
  1. Start > Run... > type "cmd" (without quotes), then "OK".
  2. Type "chkdsk DRIVE_LTR: /f" (without quotes), then hit "Enter" [where DRIVE_LTR is the drive letter of your USB drive]. EXAMPLE: chkdsk E: /f
Good luck, and please post back:
  • to provide any corrections/updates/clarifications.
  • if you have any further questions.
  • to let me know how things work out.

Windows not recognised

Press and hold the lower volume button and plug it in to the computer simultaneously and keep holding the minus button until a box appears where the message of usb device malfunctioned and click on it. Then follow the instructions and it should be recognized.

Tried the solution you offered for c240....

Go to Start --> Control Panel --> Printers and Other Hardware --> System --> hardware --> device manager --> right click on the usb port that is malfunctioning (should have a red or yellow exclamation by it), right-click it and click on Update Driver

If that fails, try another USB port on the computer to see if you have more success
