    Can you please share the solution? I have the same problem. Did it have to do with the registry? Many thanks, Joe

    usb stopped working. system restore doesn't fix it. updated drivers don't fix. uninstalling and re-scanning for new hardware doesn't fix.



    there is a constant Unknown usb device in the device manager, even though nothing is plugged in.

I have an ACER TravelMate 2355LCi Laptop. It has 2 USB Ports in the rear and 1 USB Port on the left hand side (if you are facing screen). None of them work. Are thre any drivers that can be downloaded for...


Hi!

What you could do is first check in the device manager. Go to control panel and click on system. From there on the top click on hardware. Then click on device manager. Look for any icons that would have an X, ?, or ! on it. If they do right click then click update.

If that still does not work go this page
http://tinyurl.com/acertravelmate2355drivers

and download all the drivers including the chipset and reinstall them.

I hope this helps.

USB ports not working


Method 1: Use Device Manager to scan for hardware changes loadTOCNode(2, 'resolution'); Use Device Manager to scan for hardware changes. After your computer scans for hardware changes, it might recognize the USB device that is connected to the USB port so that you can use the device.

To scan for hardware changes, follow these steps:
  1. Click Start, and then click Run.

    Note If you are running Windows Vista, click Start, and then use the Start Search box.
  2. Type devmgmt.msc, and then click OK. Device Manager opens.
  3. In Device Manager, click your computer so that it is highlighted.
  4. Click Action, and then click Scan for hardware changes.
  5. Check the USB device to see whether it is working.
If scanning for hardware changes fixed the problem, you are finished. If this method did not fix the problem, go to Method 2.
Method 2: Restart the computer loadTOCNode(2, 'resolution'); If scanning for new hardware did not fix the problem, try restarting the computer. After the computer has restarted, check the USB device to see whether it is working.

If restarting the computer fixed the problem, you are finished. If this method did not fix the problem, go to Method 3.
Method 3: Disable and re-enable the USB controller loadTOCNode(2, 'resolution'); Use Device Manager to disable and re-enable all the USB controllers. This lets the controllers recover the USB port from its unresponsive condition. The USB controllers represent the USB ports in Device Manager.

To disable and re-enable the USB controllers, follow these steps:
  1. Click Start, and then click Run.

    Note If you are running Windows Vista, click Start, and then use the Start Search box.
  2. Type devmgmt.msc, and then click OK. Device Manager opens.
  3. Expand Universal Serial Bus controllers.

    Note You might have to scroll down the list to find this item.
  4. Right-click the first USB controller under Universal Serial Bus controllers, and then click Uninstall to remove it.
  5. Repeat step 4 for each USB controller that is listed under Universal Serial Bus controllers.
  6. Restart the computer. After the computer starts, Windows will automatically scan for hardware changes and reinstall all the USB controllers that you uninstalled.
  7. Check the USB device to see whether it is working.

The computer recognizes the hardware, however scanner is not scanning. Have windows XP. How can I tell if the scanner is broken, there are no lights on it?


your scanner is ok.
But there is communication problem from computer to scanner .
For that
Check your usb cxable and usb port of computer working fine.
Try in another usb port.
If you have other port like parallel port then check it.
Check drivers of scanner are instaled proeprly.
Ig already installed then uninstall it and install again.
Also uninstall all usb drivers then restart the computer then it automatic install usb drivers .
you can uninstall usb drivers from computer with device manager.
Press windows key + Pause break key to see system proeprty then go to hardware then you see device manager then uninstall all usb drivers.

Toshiba satellite pro u400 usb ports not working. Where can I find the drivers?


I would not start with new drivers. Try uninstalling the USB ports in the hard ware settings, then have the computer scan for new hardware, which should make it automatically find and reinstall the drivers for the device. Usually it will fix the problem if that is the extent of it. If that doesn't work, then get the drivers.

Trying to install printer but usb ports are not being recognized. How can i fix this?


go to control panel/system/hardware/device manager

look for the Usb ports at bottom. any of them that are marked with question mark, will need to be uninstalled, then scan for hardware changes(actions)

that should do the trick.

otherwise, you may need new drivers..see here possibly, depending on what printer you have.
