Acer Aspire 5820T Pc Notebook - Its not detecting the usb drivers. No usb ports work and neither does the Web Cam. Showing as Unknown Device under the usb devices.


I would guess the drivers are either not installed, or the wrong ones are installed. Go to the Acer website and select your model and download the current drivers from there and install.

USB Mouse NOT Detected On Acer Aspire Laptop


lol no it has nothing to do with your bios. I'm surprised that if you know your way around a bios that you would head there. You need a driver for the mouse. In case you do know more than i am giving credit then here's what to do if you already have the driver. Go into device manager and delete anything under the mouse section that is not your touchpad. then plug the usb mouse back in.

USB ports wont recognize anything I plug in


Are you using XP? If so:
Here is what you can do to refresh the USB ports:
1. Right click MY COMPUTER
2. Select PROPERTIES
3. Select HARDWARE
4. Select DEVICE MANAGER
5. Select UNIVERSAL SERIAL BUS CONTROLLERS
6. Right click on each USB CONTROLLER and select Uninstall
7. Uninstall all entries
8. Reboot your computer
9. As your computer re-boots it will reinstall all USB connections it detects
THEN, when all other USB items have been configured and connected by the system, you then should try connecting your USB device.


If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

My usb port being not detected


Try downloading usb 2.0 drivers from microsoft.

Also look for drivers for your usb device..

check in device manager under usb devices and see if there is any yellow exclamation points next to any devices.

If that doesn't work your only option is to get a PCMCIA card that does USB 2.0

USB ports not working


Looks like it is a problem with those ports since you bought the computer.
Pls take it to a local tech to diagnose the problem or contact Acer Tech Support

USB ports not working Acer Aspire laptop


Two solutions would be to either restore your pc to before the problem started,using system restore on accesories menu, or use the recovery cd or the recovery folder Acer laptops usually have on the 'D' drive and re-install usb controllers and drivers.
