Question about Generic 2580N4 4-Port NEC Chip USB 2.0 PCI Host Adapter NEC Chipset Root Hub Windows 2000 XP
Can find acer aspire 5100 under ' universal serial bus " it say unknown device
Rather doing a driver hunt which can take hours http://download.cnet.com/slimdrivers-free/3000-18513_4-75279940.html Windows XP/Vista/7/8
it might take some time being a freeware driver solution note: it will find all of your outdated drivers
This will automatically search for and find the correct driver you will have to update every driver individually once you update you might be asked whether you want to restart or make a system restore point.
Click no to both of these then continue updating each driver free then restart once all of the drivers have been updated.
Hope this helps.

click start control panel administrative tools computer management device manager scroll down universal serial bus controllers you could see a yellow question / exclamation mark? ! or a red X
you will need to update/reinstall drivers
right click to reinstall drivers
if you can see your usb drive but its not working
ports (com&lpt) right click update driver if this fails to fix the problem
check the USB leads that attach to the motherboard usually red white green black make sure they are securely seated and have no dust build up on them dust will cause static and a lot of unforeseen problems to a computer and its parts
hope it helps

Follow the steps given below to refresh USB ports.
1. Right-click My Computer icon on the desktop, and then select Properties.
2. Click the Hardware tab.
3. Click the Device Manager button.
4. Click the plus (+) sign to the left of Universal Serial Bus controllers.
5. Right-click the device listed under Universal Serial Bus controller and select Uninstall.
6. Click OK to confirm the removal of the device.
Please note, repeat Steps 5 and 6 until all the devices under Universal Serial Bus Controller are removed.
7. Shut down the computer.
CAUTION: Ensure that the Shut Down option is selected, instead of the Restart option.
8. Wait for 5 seconds and then restart the computer. When the computer restarts, a "Windows has detected new or added hardware" message window will open.
The above steps will refresh the USB ports.
Now connect the USB devices like mouse, video camera, your external usb hard disk...usb hubs...whatever you like and the drivers should install automatically.
Tip: It is always recommended to connect the main usb devices at the rear end usb port, as they require more power to initiate.
