• USB not recognized - even when there is no USB devices at all the

  For a few days now, I get the message

  "USB device not recognized: one of the USB devices attached to this computer is not working properly." The device has not been recognised "."

  He keeps popping up in my right corner below, every 5 seconds if I don't click it. When I click on the message, I get a list of devices (ports) are available. There is an "unknown device". Maybe it has something to do with the (biometric) finger scan? This has not worked very well lately...

  Even when there is no single USB device installed (normally, I have a mouse and a Targus laptop cooling mat installed as USB devices), it keeps popping up. I tried to remove the USB port from the list (or uninstall) in the remote control, but it seems that it keeps happening.

  I got it all of a sudden, I have nothing specific to has not logged any strange devices (except for a spotlight on exit external screen, but this has nothing to do with USB). I also hear the sound for the connection / disconnection USB devics randomly when I'm on my laptop.

  Someone has an idea?

  Thank you

  I have disabled the root hubs, figured out that we caused now my mouse and other USB physical led to no longer working and that was allowed again.

  The one who gave the error message is now disabled and if the error message is no longer present.

  Result: (built in) cyberlink youcam and biometric no longer work. But at least the annoying message disappeared, so I guess I can live with that.

• Peripheral intermittent USB not recognized problem in loop

  Hello

  I have a Dell Precision M6500 laptop in a docking station with a USB keyboard and mouse attached running Win 7 Pro 64 bit.  Most of the time, the machine works fine without any problems, but sometimes, Windows will in this tight where loop every few seconds, it appears the dreaded ball peripheral USB not recognized - even if I have not added/changed and the USB device on the machine.  I tried to disable the device, uninstall the driver, etc, but nothing I do seems to fix the problem.

  Please help because it drives me crazy.

  Thank you

  It turns out that Dell thinks it's a hardware problem.  Theyu replaced the docking last week and that made it better for 3 or 4 days, but now he's back.  They will replace the motherboard this week, so we'll see...

• Laptop HP 630, generic peripheral MIDI usb not recognized

  I have a problem with a laptop HP 630 of all nine (clearance stock) (LV425PA #ABG): this is not to recognize a generic USB MIDI device (keyboard). When the unit is plugged in, I get a message "USB device not recognized". He calls an "unknown device" Manager of devices and says "Windows has stopped this device because it has reported problems. (Code 43) ». The computer has been reset with a minimal installation of Windows 7 Home Premium 64-bit for the recovery partition, with all the HP and Microsoft updates applied, but still refuses to recognize the device.

  I also have a new (stock clearance) desktop HP 4000 P. This computer immediately recognizes the keyboard when it is connected and properly installed the drivers for it. Even before installing updates - it works straight out of the box. We can exclude the device MIDI as the cause of the problem. Apart from the obvious differences of chipset, the only other difference is that the 4000 P running the 32-bit edition of Windows 7 Home Premium.

  I would appreciate help with this question, because the reason I bought the 630 HP was in first place for the use of MIDI, and it will have been a waste of time and effort if it can not be implemented in this role.

  After much effort, I have determined that it is a subtle hardware problem. The MIDI keyboard USB works fine on two other computers, but not the 630 HP. Similarly, several other USB MIDI devices have worked without difficulty on the 630 HP. Only the specific combination of HP 630 and the particular MIDI keyboard fails. It turns out, however, that they work if connected with a USB cable that is shorter than the one supplied with the keyboard. It is only the combination of three-way MIDI keyboard, cable USB and HP 630 that fails. Change any part and everything works.

  Obviously, this sensitivity to the length of the cable means that something is a little marginal on the hardware, but the fault seems to be shared between the two HP 630 and the MIDI keyboard, since they both work when paired with anything else on the same cable. I'll have to wait and see if there are other problems in the normal conditions of use.

• Why am I suddenly "USB not recognized, one of the devices USB has malfunctioned and Windows does not recognize"

  Hi all. If anyone out there in Cyber Land can solve this problem for me so I've personally you will issue an eight-pack of ice-cold beer (or a bottle of wine for the ladies lol)...

  I'll try not to waffle too guys, so here's...

  Right my PC running Windows XP. I also have itunes installed on my PC (I have an iphone 4). Upward until yesterday my iphone and itunes were working well, (once I plugged my iphone in the itunes USB port recognised that my iphone was plugged and synchronization was fine etc.).

  But now when I plug my iphone to PC to sync with itunes, I get a pop up box on the lower right part of the screen that reads... "USB not recognized one of the USB devices has malfunctioned, and Windows does not recognize."

  After visiting about 5 different sites now "Ways to solve this problem", believe it or not, I still have the problem bloody! :(

  A site proposed shutdown PC and unplug it from the power supply, then plug it back start-up and back... this as did not work!
  The other they say that I should go to Device Manager, uninstall all the USBs then restart... it did not work either.
  Tried a system restore
  Tried to reinstall itunes

  When I check the names USB in Device Manager, there is one who reads unknown device. I am literally pulling what's left of my hair now. I tried to solve this problem for almost 2 days now and still no joy. That's why no matter what input you guys would be very appreciated. I'm no PC Wizard, so please, don't think you're patronizing me if you break down things step by step for me.

  Thank you comrades, cordially, Freddy frustrated. :)

  Another said I should go to Device Manager, uninstall all the USBs and restart.

  Usually, this works... but can be very dangerous, unless you have a PS/2 keyboard.

  I also assume that you have tried all other USB ports on the computer. tried a verified USB device (for example, a flash drive) in the USB usually when you plug in your iPhone. and I tried your iPhone in another computer (I know it's rare for an error message Windows really means what he says, but sometimes the material lacks).

  Is the charge of the iPhone when it is connected to the USB port (I don't think)?  This happened to me recently, but a reboot fixed it.  I guess that that happened to you.

  I guess that you don't see the error messages in Device Manager or you must declare them.

  You can uninstall all USB devices that do not exist as follows:

  • Open a command prompt window (start > run > cmd > OK)
  • Enter the following command and press enter

  Set devmgr_show_nonpresent_devices = 1

  • Start the Device Manager by typing the following in the same command prompt window

  devmgmt.msc

  • In Device Manager, click the view menu and select "Show hidden devices".
  • You should see a category just after "Non-Plug and Play drivers" named "other devices."  Chances are that there will be a big exclamation yellow mark beside it.  When you expand the "other devices" you should see several non identified "USB devices."  Uninstall all this.
  • Reboot (with the iPhone NOT connected).

• Deviice USB not recognized. Help, please.

  So I have this Freecom 500 GB Portable external Hardrive and I have used it for several months now. It worked fine on my laptop and other computers, I'll until recently, when I plug it says: ' "USB device not recognized.". I click on the USB icon and it said: "one of the devices attached to this computer has malfunctioned, and Windows does not it." he has never done this before. In addition, there was a 'recommendation' which suggests I 'try to re-connect. If Windows does still not it, replace the device. " So I tried and tried (reconnection) but it's the same thing. USB NOT RECOGNIZED. I tried on the laptop of others and computers and the same thing happened. I have important documents stored on this hard drive... I don't think that the computer is at fault, rather my hardrive, but I'm not sure. What do you think? And are there ways I could solve this problem?

  Hi Elysem,

  As you have checked the hard disk on other computers and it gives the same error message that means there is a problem with the hard drive so I suggest you contact the manufacturer of the hard drive to get help.

  Hi @Janemaguire,

  Have you tried another USB cable?

  Because the printer is not detected on the Mac, it may be the USB port of the printer.

  What happened when you tried to install the printer on Mac?

  Error messages?

  What is the model Laserjet P1102w?

  Let me know. Thank you.

• "Usb not recognized" keeps blinking and endangered

  Hello, the notebook of a colleague, she has the message "USB not recognized" that appears for a few seconds, then disappear. Sometimes it will come back repeatedly, sometimes he disappears for long periods of time. When I was reviewing its system, is come/gone several times, disappeared for a few minutes, then flashed again once again.

  She uses a laptop HP ProBook 4310 S. It uses two USB ports. One for its wireless mouse and the other to a Kensington Displaylink (allows for laptop > Displaylink > external monitor via the USB port), who worked without interruption throughout my check.

  Any thoughts?

• Device USB not recognized - device connected USB has malfunctioned and Windows does not recognize it

  I have a HP Pavilion dv4 laptop running Windows 7 Home Edition Premium and the USB ports worked well for a HP deskjet printer and an older Casio digital camera. Then one day, the laptop decided not to recognize the Casio digital camera and gave the error message "USB device not recognized" and also indicated that the device connected to the computer has malfunctioned. This prompted me to buy a new digital camera Canon. Well, a new camera has not fixed the problem. Now, anything that is connected to one of the 2 ports USB will not be recognized by my laptop. Help!  I am at a loss to understand this.  I tried using Microsoft suggested below:

  Suggestion 1: the problem with USB devices, uninstall and reinstall all USB controllers. This allows controllers to recover the port USB of his condition does not respond.
  USB controllers represent the USB ports in Device Manager.

  a. Click Start, type Manager of devices in the search box of start and press ENTER.
  b. expand Bus USB controllers.
  Note: you may scroll through the list to find this point.
  c. the first USB controller under Bus USB controllers right click and then click on uninstall to remove it.
  d. Repeat steps above for each controller USB is listed under Bus USB controllers.
  e. restart the computer. After the computer starts, Windows will automatically check for changes on the hardware and reinstall all USB controllers that you uninstalled.
  f. check the USB device to see if it works.

  This has not fixed the problem.  Then the Device Manager, I tried to update the drivers on all the USB controllers and root hubs. While some may have received software updates downloaded, it still has not corrected the problem of unrecognized USB device after the computer is restarted.  I hope that someone knows the solution to this situation and can pass it on to me. Thanks for reading and any help display.

  Read previous messages revealed the solution for USB devices not recognized on my HP Pavilion as well as several other laptop models.  Shut down the computer and remove the battery and wait for about 15 minutes. Reinstall the battery and restart the computer.  USB ports are working to download pictures from my digital camera from Canon and charging a cell phone, etc...   I hope it helps others with this problem!

• Device USB not recognized (malfunction)

  I went on my external hard drive and an error message came - USB not recognized - device due to a malfunction. I tried switching off all voltage and turn support but still the same voltage.

  Hello ~ thanks for the reply.
