Try going into device manager and deleting the USB devices, Reboot and let Windows try and reinstall the drivers. If that doesn't fix your problem post that it didn't work and I'll get another message.

Why won't the right USB port recognize when I plug in my mouse?


Your USB ports on your computer are plug and play. If you have issues with your USB port, it is port related, driver related or device related. The following solutions will help you identify the problem to resolve your USB port issues.
To Identify a Working USB Port
Begin troubleshooting your USB ports by checking Device Manager to see if your USB ports or hubs are working properly.
  1. Click the Start button. ClickControl Panel.
  2. ClickSystem and Maintenance.
  3. ClickDevice Manager.
  4. Double-clickUniversal Serial Bus controllersand check to see if all your USB ports, hubs and controllers are functioning correctly. Any devices not functioning will have a yellow exclamation mark in front of them.
  5. If Device Manager shows any USB ports, hubs or controllers are not functioning, check for updated drivers.

To Update the USB Port Driver

An out-of-date BIOS driver can create issues with your system recognizing the USB port.
  • Watch a Video on Steps to Update Bios on Your Computer.
    1. When the update process is complete, your computer will restart again to load the operating system with the new driver version installed.

The usb port won't work on my acer extensa 4630z laptop


Hi,
Did you install any Anti virus . Check the USB port for any physical damage. Try connecting a mouse with USB port to check if its working. After all this then the issue remain the same then the USB port needs an replacement.
Regards.

USB not working


if the usb detects other devices and not your drive,the drive itself may be faulty.If you plug in other devices in the usb and it detects them the usb drive or its connector is most likely bad.If it won't detect any devices the port is bad and drivers won't help.Possibly a motherboard issue.

USB PORTS


does your usb mem stick have any light indicators? if yes , whenever you put you usb stick, does it light? if it lights are USB ports is still ok,  You just have to reformat or partition you USB stick.
(you can also try other devices like usb mouse or any usb devices that lights up when you connect it)

if there are no lights if you plug, or no indication that a power goes to your stick, its possible that your usb your are busted. if this is the case, if your laptop has a PCMIA slot, you can find a pcmia USB card, if you dont have. your only option is replace the  motherboard.

USB ports work at 1.1; s/b 2.0


Your computer is functioning correctly.
The USB ports on your laptop are USB1 ports its pard of the hardware.
Your PCMCIA USB 2 card runs at USB 2 speed and therefore when you connect a USB 2 device to this port you will not get this USB message.

No usb


If your USB ports are installed correctly and enabled in BIOS, you will see Universal Bus Controller list in the the Device Manager. Double-click your USB in the Device Manager and a dialog box will appear. Click on the driver tab and update the driver. To get to Device Manager right-click on My Computer>click on Hardware>Device Manager. If your computer has a built-in USB device and does not detect the device through the Device Manager, confirm that the USB is enabled in the computers BIOS and that the BIOS supprts USB devices.

Thinkpad T20 won't recognize usb port


You can get a PCMCIA adapter with 4 USB v.2.0 slots on eBay. It requires power from the USB port on the laptop, but the pigtail connector is included. Works like a charm! Comes from China just like everything else in this country.
