• 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.

• Satellite L30: Usb device not recognized

  I have a problem with my laptop L30.
  When I connect my phone or a flash drive or external hard drive, it is said: Usb device not recognized one of the usb devices malfunctioned.
  Tried to reinstall windows did not help...

  is there a solution?

  Hello

  Hmm. First of all, you should unplug all external USB devices.
  Then go to Device Manager and remove it all concentrators root USB and USB host controllers.
  Reboot the laptop.

  After this procedure, the operating system should recognize and should install new ports.
  Now you can connect to a plug - and play instruments. These devices should be recognized automatically. But some external USB devices need additional drivers.
  Usually these drivers are provided with the USB device.

  I would recommend this review if necessary!

Since my computer gives me the message "USB DEVICE NOT RECOGNIZED" and appears as an "unknown device" in Bus USB controller in Device Manager.

  I went to apple and they finished the restoration... I plugged the phone on other computers... It is therefore not the phone.

  I just went through two weeks of tampering with my 'old' computer trying to recognize my new 4370dn Canon multifunction printer after installing Windows 7.  I tried to reinstall Windows XP, uninstall the USB ports and hubs in Device Manager, update the printer drivers and several combinations of these elements.  In my case the ports would recognize external hard drives and flash drives, but my printer would come as a device not recognized.  Finally, what worked for me was to uninstall all the ports/USB hubs listed in Device Manager (they get automatically reinstalled with a soft reboot of the computer) again, download a driver from the Intel website (http://downloadcenter.intel.com/confirm.aspx?httpDown=http://downloadmirror.intel.com/16023/a08/infinst_autol.exe&agr=&ProductID=&DwnldId=16023&strOSs=&OSFullName=&lang=eng) chipset installation utility and restart the computer.  When I plugged the USB cable from the printer, the normal process of new device was launched.

• Device not recognized USB error message - all USB ports.

  Apologies if all this seems a bit simple, but I'm not an expert, so bear with me.

  I have a laptop Fujitsu Siemens Amilo Li 1718.

  My USB ports have stopped working in 2-3 weeks.  I get the message "USB device not recognized.  One of the devices attached to this computer has malfunctioned and Windows does not recognize... »

  I don't seem to get any yellow exclamation point in device, all my drivers in Device Manager and software are up to date and Windows Update is running.

  My mobile phone and ipod always charge when I plug them in and out of this problem, everything works fine.

  In addition to the usual updates of Windows, only two other things have occurred since last, they worked.  One was that I renewed my subscription to Norton Antivirus, the other was that my laptop battery ran right out while he was in mode 'sleep' as I did not know that I had not plugged to the socket properly.

  So far, I went through some process as suggested by various items and/or help & support on Microsoft.com.  They include:

  * (From multiple locations) system restore has failed.
  * Diagnostic software Ran Fujitsu Siemens, which says that my computer is fine.
  * Run the virus scan who come clean.
  * Tries to connect via a USB hub.
  * Deletied the USB controllers in Device Manager to re - install.
  * Changing the settings of ForceHcResetOnResume 3-to-1
  * Change AdditionalCriticalWorkerThreads from 0 to 2

  (The last two I've changed back again after neither worked).

  My opinion of beginner, it's that looks like it will create new registry details for each device when valid seem to exist already is not thankful.  Although given my lack of technical knowledge, this could well be stating the obvious.

  So, now, I drew a blank.  Anyone got any ideas?  Got 9 months left a 3-year warranty, I don't want to go through the hassle if it can be avoided without too much trouble.

  Thanks in advance!

• Peripheral PnP USB - muted, is unplug sound when not touched, "device not recognized" or a malfunction, etc...

  Here is an exhaustive list I hope what happens (it's the Microsoft forums, so I think you guys are going to read a lot of information):

  • The sound on my PnP USB audio device cancels randomly without any reason. It is not to be touched at all, and often happens when I'm even not listen to all the sounds.
  • Before he died, it emits a blur in the helmet noise as it is to be disconnected or the cord is cut or something. I have to unplug it and plug it back several times to make it work.
  • It has been for several months, working properly, this month started anything, for about a week.
  • I can't use my headset because it is loose. I had the USB key to solve this problem, because it's too expensive get taking fixed. I did not buy the device at first hand, I got it from a family member who took my laptop in for repair and the guy he recommended and we sold two of these jacks.
  • When it goes off during a game, I can't sound to return. Sometimes I can fix it on a game (as Portal 2, for example) by going to options and change the type of sound (or any) what's called it headphones to speakers, then back to the helmet. However, the game freezes often when the sound goes off and I have to remove the usb key, and in this case the game should also be repeated. In addition, everything has sound options like that.
  • This happens randomly, but it tends to happen every five minutes or every few seconds, and coincidentally it almost always happens during a loading on a video game screen.
  • It is not always give me a warning sound, especially on the games. He's just quiet.
  • Device Manager does not display a point of exclamation or question marks next to any audio device and the key USB pnp is indicated correctly. In the options of the sound in the Control Panel, there is of the sound bars next to the USB key that indicates that his is read, but it is not in playback mode. The USB pnp is listed as default device, so don't tell me to do. The microphones are turned off as well.
  • It does the same thing in all my usb ports.
  • The driver is up-to-date and meant for Windows 7.
  • I do not install the Windows updates. Updates are bad.
  • Box for what he calls a "USB stereo Audio Adapter external" StarTech.com, or "ICUSBAUDIO". It came with a disc that I used to install the driver, and I went on their website to get one for Windows 7 specifically and installed.
  • I use a computer laptop 64 bit Windows 7. In Device Manager, there are three things listed under sound: Realtek High Definition Audio Intel (r) display Audio and USB PnP Sound Device. None of the USB devices have exclamation points.
  • For the first time today, when the usb unplug sound, my computer tells me "Device not recognized" and said it could have malfunctioned. When I clicked on it for more information, he said that he could not tell me what the usb was even because it was not plugged in, which was not true. I also had a window appears which has tried to install the device driver (already installed) and then was told that the unit had been disconnected before he could do (not true). It just happened, for the second time today a few seconds ago.

• 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.
