• 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!

• 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!

• 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!

• Device not recognized USB - mouse

  Hi - write a new thread that I raised in a previous which I suppose is not sought at the most. Mods - delete please if you always looked at the other thread.

  I started intermittently gel experience with my old USB mouse, so I replaced it, that to have my new mouse (Canyon CNR-MSL7) begin to experience the same problems. Intermittent at first, but it became unusable over time - error "USB device not recognized". I tried two mice in another PC and they work fine. I use Vista is said by the way.

  I had a hard disk separated on my laptop (Sony VAIO VGN-AR71S) failure so I sent away for repair. I advised the hardware failure Sony and my USB mouse problems - she is back with a new HD but they said they found no defects with the USB.
  the mouse worked for about 1 day before I started getting the error 'USB device not recognized' again.

  A system restore will obviously work for me because my hard drive has been replaced and I have the same problem I had before, despite the installation of the more updated version of vista to Sony.

  The laptop has the most until drivers date etc, but does still not more than 95% of the time. I went through different threads here and I checked that everything is fine with the USB etc hubs, but not joy.

  I checked the ports are feeding correctly and that they are.

  I tried power down, stop and remove the advice of battery given here that seems to have worked so well for people but it does not work for me unfortunately.

  Is someone of MS can advise if it is sought in order to create a solution that works for those of us who does not work for the option "disconnect"? I tried all the solutions to this problem listed on the various threads on this subject in this area and other forums. Or can someone tell me if there is anything I can buy to remove the problem? Equipment etc? I thought that an upgrade to windows 7 could help, but I've seen a lot of discussion here that clearly show the same problem that appears for people who use it.

  Another new mouse like the ticket to me if you have hardware problems (and this is
  my best bet).

• 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:

  

• 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.

• LASERJET 1022 device not recognized USB

  When I connect my laserjet 1022 printer on my computer, I get the message "USB device not recognized". normally, I use Windows 7 64 bit, but I try to connect another computer that has Windows XP OS. Win7 or Win XP allows to print anything with appropriate drivers. I think that this is not a driver problem, it seems to be a hardware problem. Everybody respected this problem before, I can't use this printer.

  also we have an another 1022 that works, I replace my printer to it and my printer is not yet printed.

  If I have a hardware problem somebody advice me anything.

  Thanks for your help,

  The printer will print a test if not connected to the computer page? If this isn't the case, then the hardware problem is the printer that is connected.

  If you print a page of test if not connected to the computer, then the problem is on the side of the computer. Try another cable USB or port. Some computers, especially laptops, can have very delicate USB ports (my laptop Lenovo's ) and USB cables can go wrong.
