• USB device not recognized when connected to Toshiba Port Replicator II

  I recently bought the Replicator above, loaded the software, restarted my computer and only then connected the device according to the instructions.

  I get the error message "unrecognized usb device".
  When I go in my gear and check for driver for this device 'unknown' told me that no drivers have been shipped for her

  So my Replicator does not.
  I deleted the software and reloaded with the same result

  I have a laptop Tecra A8 running Windows XP Service Pack 2
  Any help or suggestion would be appreciated

  As much I know PortReplicator II only is not supported for Tecra A8. According to the sustained specification is Port Replicator III + only.

  If you try to use the option not supported, it is not easy to give any help.

• 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.

• USB device not recognized... Unplug the thing does NOT work

  It baffles me that THOUSANDS of people have this problem, or a variant of it, and no ONE at Microsoft or elsewhere also offers a real solution. Unless of course you want to count the method "unplug your computer", which is the most foolish band-aid for a problem I never heard, even if it works for a lot of people (most). I, unfortunately, am one of those for which the "disconnect" method magic does NOT work. I tried everything what all other posters and responder suggested (BIOS upgrade, change Legacy BIOS definition Enable to disable to activate again, driver updates, uninstall all USB, full power down and restart hours later, use CMD prompt to show only devices, etc.) and do not know what else to try. I would really like to see a REAL answer as to the cause of the majority of the questions posted about the USB error outside the usual "restore your settings, use your restore disk, unplug it, replace your USB key, etc etc etc. HEY! MICROSOFT! SOLVE THE PROBLEM! OR, Hey, here's an idea, a news for you, I'm sure that... don't they exude products until they have been tested (NO! I mean really, fully tested [see XBox 360 RROD])

  In case anyone reading this is a real working solution, I'm on a Toshiba A135-S2386, Vista Home, and each USB port is unusable on any device. All ports feeds the device and noise sounds to indicate that a USB device was attached and then proceeds to the display of the error "USB device not recognized" and shows and shows an unknown device connected. It does this for any USB device.

  FINALLY: PLEASE PLEASE PLEASE DO NOT POST A REPLY IF YOU USED THE METHOD OF "DISCONNECT", AND IT WORKED. Grats to you for fixing your computer, but I can just not read another 400 posts of "wow it worked for me great fantastic" when it does NOT work for everyone. I need something new and real. (Sorry to be all grumpy, but I'm tired of these kinds of problems from companies making billions off the coast of junk, defective, half finished, produced a car!) "You listen to Bill?)

  UPDATE: just ran a scan of the system file Confirmation via an administrator command prompt and it's clean...
  ALSO - was not that before, but now whenever I do a complete power down / reboot thing that it gives me a "Bad Checksum" error and I have to reset the date and time in the BIOS. I need to change the battery in MB? As I said it did not have this before and the USB error was produced, but could this be the problem? Bad battery MB CMOS?

  The bios of your motherboard is probably damaged.

  step 1. See if you can find a previous version of the bios of your motherboard and return date of the bios.

  step 2. Find the latest version of the bios of your motherboard and update your bios.

  Do not use a registered version of your current version.

  To check the problem is the motherboard or operating system. find something like a live Ubuntu CD

  http://www.Ubuntu.com/desktop/get-Ubuntu/download.

  or

  Make a Ultimate Boot CD for Windows

  http://www.UBCD4Win.com/index.htm you are using windows xp or borrow a copy to UBD4WIN.

  Both of the above run in memory (does not load on hard drive.

  Both a bit slow, but are excellent tools.

  Works like a normal computer.

  If you can see you USB devices, magicjack, ETC. your BIOS is not corrupt or motherboard problem.

  In normal windows if you see not the USB devices, magicjack, etc your windows install is corrupt.

  Reload Windows of difficulty.

  If you you do not see the magicjack, USB devices, ETC., your BIOS is corrupt motherboard or other problem.

  Redo your BIOS as described above.

  All other unwanted do not work , he was done !

• Constant pop up of the notice that says "USB device not recognized" after the device has been disconnected

  Trying to connect a Sony W760 to PC Suite and receive the notification as the "peripheral USB is not recognized. Clicked on the indications of alert and monitoring. The device is not installed. Computer restarted, but the alert keeps popping up every 10 to 15 seconds. How to stop?

  Found the answer to the problems by accident. I had turned off my Avast, during the installation of the programs, but did not know that the computer came with Norton already active. Nothing on the screen noted that it is there. The Sony site, under the heading troubleshooting USB and I saw it mentioned to disable McAfee. Became curious and went to control panel > programs and features looking around and found the Norton. Uninstalled, downloaded programs from Sony, install and everything works fine. Just a reminder, check all your security system before installing programs.

• 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:

  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.
