• G1 laptop computer 350. All USB ports stopped working

  Hello. I hope someone can give me some advice on this subject.

  I turned on my laptop the other day and none of the USB ports worked. Any device I plug is not recognized and there is no power to the USB ports. (Goal of mouse does not light, bright external HHD is turned off. USB flash drives do not light up.) Powered deviecs are not also recognized is more than a problem of USB power. (When I say not recognized I mean there is no indication that they are still connected, no pop up error message or indication in Device Manager that the device may be defective).

  I tried to uninstall all USB drivers without result, I started from a Linux CD and a Win7 ERD without result. I also tried a hard reset, also without result. I have reset the BIOS and verified that USB is enabled in the BIOS but that also made no difference.

  If anyone has any useful advice, I would be very grateful.

  Another possibility is to reinstall or 'repair' Nero over himself.

• USB ports stopped working unexpectedly

  Hi, I am currently on "Toshiba Satellite C655"run"Windows 7 Home Premium". It's a laptop of 2009 model (2 GB). Last night (24/02/14) my USB Ports stopped working, they have been and continue to read anything every time I have to plug my devices. I usually only connect a cooling block and a USB mouse to the computer. They worked perfectly until I disconnected the. When I reconnect them, they work momentarily, and then I hear the beep sounds when you eject a device. I tried to connect several flashdrives, a printer, and one I tried the following hotfixes:

  Note: The order of numbering has nothing to do with the order, I tried to apply each patch unless specified elsewhere. This computer had Windows 7 Home Premium REINSTALLED at some point. Just for your information. This message was made when there are others with the same problem is due to the fact that no solution not specified by Microsoft Technical Support or the Microsoft community were effective.

  1) System Restore to the last known point, where they worked (and still). (Point restoration @ 15/02/24)

  2) Windows Update

  3) turn off the computer, disconnect the battery and the power supply and holding 'On' button for 10seconds.

  (Note: whenever I turn on the computer now they work only for a moment, usually from 60 to 180 seconds.)

  (4) Start > research ' Device Manager '> "De Bus USB controllers" Expand and turn off and restart the computer. They are re - activate automatically but my problem persists.

  (5) download and run "Microsoft FixIt.WinUSB... ", on the 1st, I had a problem with devices not updated. But I actually watch updates by using Windows Update and ""searching for hardware changes "" on USB Bus controllers "." I then did a 'System Restore' and now Microsoft FixIt found no problem but the USB Ports don't always work.

  (6) will ' services.msc"and change the Startup Type of Manual to Automatic for Windows install and restart Windows."

  7) regedit

  8) sfc/scannow

  I am really lost with this problem now. My laptop works and worked perfectly fine until this problem occurred. I have fixed minor problems with computers before, but this is a bad joke for me now. If someone could please help me with this problem I would appreciate it a lot. Thank you very much.

  Thank you for your help, but I discovered something funny on my computer. My cooling package (product name: Laptop Cooling Pad NSB;) HYCF-6181-2 model number) is to disable my USB ports when I plug. If I leave it unplugged and restart my computer, my USB mouse is still working on a port. Also tried using my USB and other devices. The problem is my block of cooling that strangely disables my USB ports, whenever I plug. Thank you very much for your quick response, fortunately the answer might help me in the future. For now, I have solved my problem.

  I get error messages saying unregognised device or usb device stopped working or windows stopped device etc.

  Unplug the hub and repluging it ususally actually come back to life.

  any ideas?

  Stafford

  Hello

  Have you tried to connect devices directly to the USB port?
  Try this and see if the USB device is disconnected, as you mentioned that using the external USB hub.

  Generally speaking, it is difficult to say what might cause this
  You could try updating the chipset driver.
  Of course, you should also check the USB port settings, and power management options for economy.

  In device manager-> USB root & hub-> properties you could disable for unique energy saving USB ports.
  This also on Win 7 power management.

• all 3 USB ports stopped working - MX30

  As a result, none of the 3 USB ports on my old MX30 work of 2 months. I unchecked the option in the hardware Manager of devices for energy saving, nothing helps. First of all, only the mouse stopped and I thought the mouse was to blame, but all of a sudden the machine does not recognize the USB memory key more.
  Any advice would be very welcome, because I can't work!

  Respond to my ad. I've updated the drivers for the USB host controller and BIOS and USB ports running again.

• Internal card reader & USB ports stop working in Windows 7 64 bit - HELP

  This seems to be VERY popular problem between Vista and 7 users. I can't find the right difficulty any where. I have a HP Pavilion of D5200T running Win 7 Home Premium 64-bit. (I can provide more specific if necessary specifications). I read a few other posts in this forum with exactly the same problem as me, I tried the suggested fixes - most of them anyway - and my problem persists.

  This is the story of the kind: bought PC Cognac nine in June 09. It came with Vista Home premium 64-bit. On the front panel, I have the HP 15 in 1 reader cards and below that another panel with micro/headphones, 2 USB ports and 1 port Firwire catches. They all worked great worked great, no problem at all. I bought Windows 7 and improved in October 09. These two USB ports and card reader have been in place since then. I turn on the computer or restart works and they. Slide into a car SD, CF, whatever it is. Little green light turns on, windows automatically opens on the screen indicating the contents of the card.

  The card reader is no longer everything first. It may be 15 minutes later, perhaps hours. I slip on a map and still get the little green light but nothing on the screen. As if no card has been inserted. 2 USB ports will do the same thing, just much less frequently. I step a USB item and I have an error message saying: is not recognized or not installed properly. If I restart - they are all back to work very well.

  So... this problem only started after the Windows 7 installed, then it is clear to me is where the problem lies. When card readers or USB is in their State of non-working, I'll go to Device Manager and see that they are always listed, and there is no indicator of errors.

  This is what I remember by train so far, without success. I uninstalled devices from the Device Manager, driver too. I tried unplugging them from the card, restart, reconnected, reinstall. I tried different plugs on the motherboard. I can't find the latest drivers. The courses are MS 21/06/06 6.1.7600.16385. I think I tried all utilities integrated in Win7 to try and diagnose, and none of them produced no results. I tried to disable the sleep function. I even reached out to HP support, and the best they have resulted so far is that the card reader is bad. They are sending me a new, but I do not think that this problem will be solved.

  As I said, I see this problem or similar to many, many forums but I have rarely seen a happy ending where it was fixed. Someone at - it the key? Help, please.

• Satellite L850 - USB Port stopped working

  Hello guys,.

  first sorry for my bad English, im from Germany.

  My new clearly L850 satellite has had some problems with sound-Port USB.
  I think it's the Usb3.0 Port on the left.
  While I'm workin with an external keyboard, the USB Port has stopped working and cannot identify the keyboard.
  All other devices that I put there, are out of order, but when I put an external hard Powerdevice with separate data for laptop, that he is there something ist connectet, but can't identify it.

  I have try all troubleshooting close it, like install new drivers, disable ports and restart and any kind of it.

  So maybe you have another tip for me?
  Or do I have to bring my laptop to the store for warranty?
  A Windows 8 64 bit on it, maybe it will help.

  Best regards, neothic

  Have you tried reinstalling the driver USB 3.0? Please try and check the functionality. If this will not help I recommend you do the ultimate test: back up all your data and reinstall Win8 using recovery media. Test it with clean OS preinstalled and factory settings.

  In the worst cases, you should contact the nearest Toshiba service provider and ask for help.
