• device not recognized by Windows

  Hello

  I have a problem with my camera, I saw a lot of posts here of a similar question, so do not know how to see that I have not seen any solution.

  When I connect my camera to the USB port, Windows will try to install the drivers but complain that the device is not recognized.

  I can see new driver added to 'my computer' under memory card format, but it is not accessible

  If I try to delete the driver of drivers installed, it will reinstall with the same problem

  If I connect using tips I've seen here (hold down and press the Center button) it will be recognized, but only for this session, moreover, when I do, I can't see or delete songs I've stored there before, but I can add new songs.

  In any case, I can play those songs.

  The format of the device or reolve somehow?

  On the device, go to

  Settings > USBMode > select MSC.

  That will force a permanent connection of MSC. You will not see the content of the PSG. First, you could reformat and start over.

  Go to settings > Format > select Yes

  I advise you to update the firmware while you are here.

• USB 2.0 Bluetooth DEVICE NOT RECOGNIZED - Equium A100-147

  Hi all!!!

  I have posted b4 about my problems of BT, but still no further forward.

  I have a 2.0 usb toggle universl BT, my last worked well until it broke.

  Since I had xp pro installed, but my USB does not recognize my rocking do not even have a pop up? any ideas.

  When I plug it 3 fast Dong

  Unplug and made 2 Dong

  I tried to install the drivers usb, but nothing.

  do my head now... Please someone help me resolve this issue!

  As far I know Equium A100-147 doesn t support the internal BT module and so if it was not equipped with the BT Toshiba stack.

  If you use an external 3rd party module BT, then you should check if there are drivers designed specially for this external BT dongle.

  Also, check if the BT dongle would be recognized in the Device Manager.
  If there is no dongle BT listed in the list of devices, then remove all controllers and hubs of UBS in the list and restart the device.
  After rebooting again Win XP should initialize the USB ports again and then you try to plug the dongle BT again.

  Good luck

• Not getting FireWire devices not recognized on Windows 7

  Recognition FireWire problems
  My computer with Windows 7 Prof 64 bit doesn't recognize firewire devices that I connect to it.  Device Manager displays the drivers 1394 work very well.  My WD external hard drive so my Sony HDR HC5 camcorder are more recognized when I plug them cold or hot plug. Two of them have worked very well for more than 2 years and now for some unknown reason, that they stopped just recognized on any of 3 firewire ports available in my new DELL Studio8000 PC with a firewire card Texas Instruments PCI with 2 firewire ports. I have replaced the cables, uninstalled the drivers and reinstall them without any result.

  Hi DMJ06,

  Thanks for your post.

  If the manufacturer indicates a hardware failure on the device, it is likely, it is accurate.

  If it does not work on any of your computers, it's a strong argument for their suggestion.

  I propose to repair the unit if possible.

• 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.

  Error "USB device not recognized", but nothing is plugged in and my webcam is not working. It says webcam not connected

  Hello

  Since you said it worked very well recently, I'll try to do a system restore at this point in time.

  See this link: http://windows.microsoft.com/en-us/windows7/products/features/system-restore?SignedIn=1

  In addition, see the response of the Meghmala and follow the instructions listed there. I think that the three method might be the best of the bunch for you, but they have all the right steps.

• 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. It's not show my mouse and when I go to Bluetooth settings and try checking the box (and pressing OK) under the discovery that reads "Allow Bluetooth devices to find this computer" it gives me an error saying that this is impossible.

  Help!

  The manufacturer of my hardware (bluetooth mouse) will not be able to explain why this struck dead window device unrecognized USB is coming non-stop. Above tutorials did not help at all.

  Hey wsdp

• 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 is not recognized on Satellite Pro A100

  I have a Satellite Pro A100 828 running Win XP Pro.

  He is supposed to have integrated bluetooth but when I install the bluetooth stack, a message appears saying peripheral usb has malfunctioned and is not recognized by windows.

  In Device Manager, it is listed as an unknown device.
  I tried different versions of the bluetooth stack, but the same message still appears.

  Is there a software fix for this or does this mean that my hardware is defective? Would be grateful for any advice.

  Thank you.

  Hello

  where downloaded battery Bluetooth? And another question: do you have bluetooth never work properly? It would be interesting.
  Try another might be to download a Linux Live-CD and to check if the problem is perhaps more a hardware related issue.

  So, if you need an alternative download source then try this address:

• LASERJET 1022 device not recognized USB

  When I connect my laserjet 1022 printer on my computer, I get the message "USB device not recognized". normally, I use Windows 7 64 bit, but I try to connect another computer that has Windows XP OS. Win7 or Win XP allows to print anything with appropriate drivers. I think that this is not a driver problem, it seems to be a hardware problem. Everybody respected this problem before, I can't use this printer.

  also we have an another 1022 that works, I replace my printer to it and my printer is not yet printed.

  If I have a hardware problem somebody advice me anything.

  Thanks for your help,

  The printer will print a test if not connected to the computer page? If this isn't the case, then the hardware problem is the printer that is connected.

  If you print a page of test if not connected to the computer, then the problem is on the side of the computer. Try another cable USB or port. Some computers, especially laptops, can have very delicate USB ports (my laptop Lenovo's ) and USB cables can go wrong.

• Device not recognized USB keeps popping up - Windows 7

  I have been using a wireless keyboard with the Sony Vaio laptop with Win 7 64 bit for a year and, yesterday, the keyboard no longer works.  The keyboard works fine with 2 other laptop computers (Win7 and XP).  Even when I unplug the dongle, the message "USB device not recognized" keeps popping up ever minute or more.  All other USB devices (i.e., memory keys, portable HDs, etc) work very well.  I uninstalled all the USB controllers in Device Manager and rebooted (multiple times).  I tried to go back to a system since a couple of days restore point.  Nothing solves the problem.

  I wish that the keyboard to work again, but also really want the message stop appearing.

  Thank you.
