.There are a lot of virus' that will disable your USB ports. You can change the settings in the registry to enable them again.

Open registry (START > RUN> type regedit) and navigate to the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet \Services\UsbStor

Now in the right pane, double-click Start and type 3 in the Value data box (Hexadecimal) and quite the registry editor.

Usb ports wont work


Go to Control Panel, System, Hardware, and Device Manager. Look for serial ports/USB ports. Verify installed and active. If not, go to Bios 'setup' at start-up and activate from there. Be sure to save and exit even if you change nothing--otherwise everything returns to default.

USB not working


If none of your USB ports work, there could be a problem with your USB controllers. Uninstall the USB controllers via Control Panel - System ... and reboot your laptop. They will reinstall upon bootup. Good luck.

Acer Aspire 5100 Problem , Keyboard not working even you plug another one on USB port , USB port also not working while the notebook is on and full charge


Take a look in Device Manager to make sure all devices are working correctly and that there are NO Yellow or Red marks.
If Yellow Exclimation is on the device, try reinstalling the driver for that device.
If Red X Mark is on the device, enable that device.
If this does not solve your issue, you should take your Laptop to your local computer repair shop.
Good Luck.

Acer notebook usb not recognized


Sounds like a hardware issue. I would guess that there is a bad connection between the usb's and the motherboard. If you are comfortable dismanteling the laptop and re-soldering the usb's than give that a try, but I would recomend you give it to a pro.
Here is a link that explains the process. http://www.insidemylaptop.com/taking-apart-acer-aspire-5100-laptop/

All USB ports not working


Sounds like a shorted out board. If you use a faulty device.. these can EASILY short out the USB controllers on the motherboard.

Alternative is to purchase a "PCMCIA USB expansion card" till you can replace the motherboard.

best wishes.
