USB not recognizing devices

• 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!

• USB not recognized device error with the Logitech Wireless Mouse

  Greetings, Im having trouble getting my recognized usb wireless receiver. Worked fine on Vista premium edition... recently updgraded to windows 7 do not work now? I tried Device Manager to scan for hardware changes... no luck. I tried the Drivers but logitech claims it is compatible with windows 7 and you don't need all drivers... would appreciate any help!

  Thank you

  I also had this problem, but finally found a solution. You need to reset the motherboard. It is more than a simple reset of the computer as the motherboard continues to feed into "stop".  You must turn off the system and unplug a few minuets.  In the case of my laptop, I also removed the dough for good measure.  Then I turned it back and the mouse worked without trouble or the same recognition that there had never been a problem.

  Credit when it is earned, I found the solution here http://www.online-tech-tips.com/computer-tips/usb-device-not-recognized/

• 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. Then I went to print something and the same message came. However, I used my printer today without any problem. I don't know what happened. Advice please? Thank you very much. Aide-de-camp

  Hello ~ thanks for the reply.

  Just to say that I read somewhere switch all switch off and leave it for half an hour - then turn on everthing. Miraculously - it worked!

• 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).

• HP LaserJet P1102: USB not recognized during installation of HP LaserJet P1102

  I have a Sony Vaio VPCEH computer laptop with Windows 7 and when I run the disk I got with the printer on my laptop, that the installation procedure works in what concerns the section "Install printer Software". When you are prompted to turn on the printer and connect the cable USB to the laptop it says 'USB not recognized '.  I tried all 4 slots USB into my laptop but the USB still appears as an unknown device with an exclamation point in a yellow triangle. I searched internet solutions and tried to uninstall the unknown device in Device Manager and restart the installation with the disc, I also tried clicking on the unknown device driver software update but it says the software driver is up to date and still, it shows as an unknown device and is not recognized. I also tried to uninstall the HP software from the disc on my laptop and that reinstall but nothing has worked. I felt for over 2 weeks now and have not been able to use it because of this problem and I really need for University, so I would be very happy if someone could please give me a solution to this problem

  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.

• 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.

• Device Intel WLan 6230 USB not recognized in Satellite L655 running Win8

  I installed the Intel Centrino card 6230 WLAN for laptop Toshiba Satellite L655 of my wife (introduced to my HP laptop, but due to their allow list, it does not start... but it's another story).

  Wifi works a treat, and I'm pulling in a little more speed of 100 mb/s (http://www.speedtest.net/result/2328501761.png) to connect to my router dual band 5 GHz.

  I understand this card features also the Bluetooth capabilities and I think that is where my problem comes from.

  I get a warning balloon will appear in the system tray saying "Device not recognized USB" (http://imageshack.us/f/208/intel62301.jpg/).

  I followed various supposed fixes, including the removal of the drivers, as you can see from the photo I've already done. As I'm under Windows 8 Pro 64 bit as soon as I restart the WLAN driver is automatically re-established.

  I tried to install the drivers several times, but I always get the error message as below: -.

  http://ImageShack.us/f/41/intel62302.jpg/
  http://ImageShack.us/f/822/intel62303.jpg/

  I'm looking for one of the 2 solutions.

  1. get the device working properly - Bluetooth & Wifi - there Toshiba never do drivers for the 6230?
  2 disable the ToolTip of the USB, I can do this as a stop, but as soon as I reboot it is back bothers me!

  Any help is appreciated with gratitude.
