• 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!

• 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.

• Satellite L30: Usb device not recognized

  I have a problem with my laptop L30.
  When I connect my phone or a flash drive or external hard drive, it is said: Usb device not recognized one of the usb devices malfunctioned.
  Tried to reinstall windows did not help...

  is there a solution?

  Hello

  Hmm. First of all, you should unplug all external USB devices.
  Then go to Device Manager and remove it all concentrators root USB and USB host controllers.
  Reboot the laptop.

  After this procedure, the operating system should recognize and should install new ports.
  Now you can connect to a plug - and play instruments. These devices should be recognized automatically. But some external USB devices need additional drivers.
  Usually these drivers are provided with the USB device.

  I would recommend this review if necessary!

  I just went through two weeks of tampering with my 'old' computer trying to recognize my new 4370dn Canon multifunction printer after installing Windows 7.  I tried to reinstall Windows XP, uninstall the USB ports and hubs in Device Manager, update the printer drivers and several combinations of these elements.  In my case the ports would recognize external hard drives and flash drives, but my printer would come as a device not recognized.  Finally, what worked for me was to uninstall all the ports/USB hubs listed in Device Manager (they get automatically reinstalled with a soft reboot of the computer) again, download a driver from the Intel website (http://downloadcenter.intel.com/confirm.aspx?httpDown=http://downloadmirror.intel.com/16023/a08/infinst_autol.exe&agr=&ProductID=&DwnldId=16023&strOSs=&OSFullName=&lang=eng) chipset installation utility and restart the computer.  When I plugged the USB cable from the printer, the normal process of new device was launched.

  Hello

  It seems that you are getting the popup "USB device not recognized", when nothing is connected.

  What is the brand and model of your computer?

  I suggest to uninstall the USB controllers and check if you get the context menu.

  
  

  Method 1: Remove and reinstall all USB controllers

  
  

  a. clickStart, type devmgmt.msc in the start search box and press ENTER.

  b. expandBus USB controllers.

  c. right-click on each device under theBus USB controllers node and then click Uninstall to remove them one at a time.

  d. restart the computer, and windows will install the rear USB drivers.

  If reinstalling USB host controllers fails to resolve the issue, go to method 2.

  Method 2: See the procedure suggested by johnkelly46 responded on October 26, 2009, from this link.
