  Check the settings/configuration (BIOS/CMOS) that get started - often F2 so watch you start screen.
  Check that the USB is enabled. If these methods fail you will need a real computer store

• Touch screen does not work and the message "USB device not recognized".

  I have a Samsung Ativ book 9 Lite. Everything works fine until that recently when my touch screen stopped working (is there a function button that could possibly have it?) and I constantly get a notification from Windows Explorer that says "Device not found USB." When I go to the Device Manager page it constantly keeps refreshing, so you can't click on almost any. There is an element that shows as unknown, but if I try to uninstall or disable, it happens immediately. I just downloaded the latest driver for the printer I only use and still no luck.

  Any help?

  Hey Jake,

  I suggest to download the latest driver available for the touch screen on the manufacturer's Web site and install it.

• PRS-600 USB device not recognized

  I am unable to get ereader PRS-600 to be recognized by the computer (Win7).
  I tried to update the software (even if I think it's in)
  (date) but the window 'connect a PRS-600 to update' does not progress and the update button is dimmed.
  I deleted the "unknown device" in the drivers, but when I reconnect the USB cable and the ereader, I always get the display of device not recognized and the message "USB device not recognized".

  I seem to have solved the problem. I contacted Sony through esupport and a chat with a tech.

  Make sure that the battery has some charge inside. Completely charge if you can.
  Stop eReader (fully)
  Remove the SD card
  Press the button Reset (at the bottom of the ereader)
  Turn it on
  While the display shows "Open book", at the same time press the button to "turn the page" (back) and the Volume button until the "Reset All" + screen
  Enter 'Yes' to reset the ereader. You may need to configure the screen (X button with the tip to draw at various points)
  If you charge the battery, you may need to contact the support chat for sorting.

  Good luck!

• Bluetooth mouse stopped working & USB device not recognized error

  Laptop using Windows Vista

  I was using my bluetooth mouse when I plugged my mobile phone (via USB cable) in charge. I have done this before w/o a problem (perhaps in another USB Port, now that I think about it) but I did this time and I instantly lost the ability to use my bluetooth mouse and the "USB device not recognized" bubble popped up. Now, this window pops up almost every 10 seconds even with disconnected USB mobile phone.

  I went to bluetooth devices trying to pair my mouse w / new laptop and I can not.

  Hi, this problem recently just started to happen, nowhere I can say. Whenever I turn on my computer or it wake up from hibernation, a message from the task bar appears saying "USB device not recognized". However, there is nothing plugged one of my USB ports. I have three USB ports available, and all are empty. I tested all three ports in something by plugging, and all three ports seem to work well. What can I do to get this message to stop appearing? Thanks in advance!

• USB device not recognized when I connect my iphone to my computer

  Original title: USB device not recognized

  I get the error message "Unrecognized USB device" when I connect my iphone to my computer.  It is the same as the one I use for months.  Same computer.  Same sync cable.  I have changed everything, including hang iphone to my wife instead of mine and get the same message.  I also did a restore on my computer that doesn't change anything.

  Hello

  At this point, I think it's a good idea to run a scan for viruses/malware on the PC with the anti-virus software that you have installed.

  Also, if you haven't already, I would try removing the USB controllers and restart again, now that the updates of Windows are installed. Don't forget, you can even download the drivers directly from manufacturer support site for your PC, if they install automatically when you restart after their removal.

  Finally, take a look at the thread I linked below. The first answer is quite similar to that mentioned above in this thread, but there are also a few other really good measures listed there as well. Then take a look at the linked thread and see if that helps at all.

• His number disappointed + B500 USB device not recognized at startup

  Hello

  We have 2 B500

  whenever I'm starting, after loading windows they give me an error "USB device not recognized" I don't know what to do any help will be greatly appreciated as it is strange that both machines are giving the same error.

  also on one of the machines the sound does not work, I tried to get out of trouble, the diagnostic says the speakers are working properly, but not her out at all.

  I'm kind of disappointed by these questions, we always buy at Dell, but we thought we would give Lenovo a chance, the machines were barely a few months, when the problem started.

  advice please?

  That error usually comes up when a non bootable USB device is connected. Check the Bios and make sure that the CD drive and HARD drive are loading first. That should solve your problem. If this is not the case, make sure that you don't have any USB stick or disk external HARD connected until the PC load.
