• 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!

  I connected the USB cord to transfer information from your old phone to new phone via Itunes.  Since that time that I keep getting a pop up message that says: device not recognized USB, the defective device, windows does not recognize.  Nothing is plugged in, but message appears every few seconds.  How can I get him to stop?

  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.

• HP Color Laserjet M277n MFP: How to use the black cartridges only when the color toners are empty

  Hello team HP,

  I recently bought a HP Color Laserjet MFP M277n I printer I print black & white user only and really don't need color prints. How to set the printer options to print only black & white? How can I replace only the black cartridge when the color cartridges are empty? How many prints (approximate), we can take by toner?

  Kind regards

  Christèle

  Hi @Pavumba,

  Welcome to the Forums of HP Support!

  I understand you're wondering how to use black ink only on your HP Color Laserjet M277n MFP printer. I would be glad to help and don't forget to come back to this thread and check "Accept as Solution", if I have successfully helped solve you the problem. If you want to say 'Thank you' to my effort to help, click on the "thumbs up" to give me a Kudos.

  I see that you wonder if you need to replace the color cartridge when it is low. This printer is a printer AIO, therefore, you need to replace the ink cartridge when it becomes too weak to be able to resume printing. However, if you print mostly in black, you can configure a preset black only to print in black and white. This would help reduce the use of the color cartridges.

  NOTE: Composite black - for black and white images and photos, a mix of colors called 'composite black' can be used to achieve the quality significantly improved picture and soft gray tones that can be achieved with only black toner. For users who want to print images using just black toner, many HP printers color customer offer configurable options allowing the client to print using only black toner. For example, by selecting "print in grayscale" in the printer driver Specifies print using black ink only. For more information about the use of the toner cartridges, please see this article: how the Toner is used.

   

• 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 !

• Error "USB device not recognized" but nothing is plugged

  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.

• 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:

• 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.
