  Please help me

  I put t know what USB device do you use but if it doesn't work, you must have the driver for this device of some. Part material Toshiba doesn t support third so try please talk with your internet provider and ask for help.

  Another thing: I put t know where you bought your Qosmio but I assume it has been offered to Pakistan. The right support page should be http://asia.toshiba.com/pakistan

  As far as I know, optical drive uses the standard Microsoft driver so that you won't find a driver for the CD-rom drive.

• Windows 7 - "USB device not recognized" - to load the new electronic Cigarette device. Help, please?

  I have Windows 7 Home Premium.  I just bought a unit of the electronic cigarette, manufacturer is "Innokin Cool Fire IV", the usb charger plugged on Acer laptop and comes to the screen "USB device not recognized".  I loaded different brand before without problem, I don't know what to do and I am NOT GOOD WITH COMPUTERS!  My settings are at "install updates automatically" and I DON'T WANT WINDOWS 10!  Can someone help me please?  Thank you for taking the time to read this.

  This seems to indicate that the charger has actually been detected as a device, but Windows can not work it out.

  Normally such a device should only connect to 5v and 0v pins and have no connection with the pins of data, in this way, that it will not be seen by Windows. I would be concerned by the quality of the device if it has some form of data connection. If you want to continue with this charger, that I would recommend to use a power supply of 5v USB instead of risking the USB port of the laptop, a lot less expensive if it does not. It has been reported several eCig Chargers catch fire. Something like this:

• Booklet - USB device not recognized error message

  Hello

  I have a workaround for this problem that occasionally occurs. It's just to reconnect the USB hub (as recommended by Windows). I was wondering if anyone knows why this happens and how to fix it. The error is: -.

  "Unrecognized USB device. One of the USB devices attached to this computer has malfunctioned and windows does not recognize.

  Roob (2 ports) USB hubs - unused Port, unknown device.

  Recommendation: try to re-connect. If Windows does still not it, replace the device. "

  I can't wait to hear back on your part.
  Kind regards
  Julia.

  Hello Julia

  It is always advantageous to mention which model you have exactly. Of course the external device is not correctly recognized. Check if there is a driver that must be installed before you can use it properly.

• 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!
