Before telling my problem, I need to tell you guys one thing. I searched Google, Superuser and StackOverflow a lot and I can't find anything useful.

I use a Windows Server 2008 R2 machine with Intel i3 processor, 4 GB RAM. Its motherboard is ECS H55H-CM. From yesterday no USB devices are working - keyboard, mouse, pendrives, card readers, printer. Am using PS/2 mouse and keyboard now. 

Here is the Device Manager.

As you see there, the USB controllers (Intel (R) 5 Series/3400 series Chipset family USB Enhanced Host Controller) was mentioned below Huawei Mobile Connect. After an unistall and restart they started to appear under Other Devices.

This is the error when I looked in the properties -
"The drivers for this device are not installed. (Code 28)
This operation requires an interactive window station.
To reinstall the drivers for this device, click Reinstall Driver."

* I tried unplugging and plugging many times.
* Tried to install drivers, and still nothing happens. Device Manager is the same even after installing drivers.
* Uninstalled each USB controller and restarted my system.
* Scanned for hardware changes.

I tried each and everything I saw in many websites and nothing did any good. So what should I do to make the USB devices working ?

As a last try I uninstalled both the 'Other Devices'(refer first image) and restarted my system. After restarting 7 Found New Hardware windows appeared I choose 'Ask Me Later'. Then I connected USB Mouse, Pen drive, printer and keyboard. All devices worked except keyboard. So I removed USB keyboard and plugged PS/2 keyboard. Now the Device Manager looks like this -

If I select to install drivers when the 'Found New Hardware' window appears none of the USB devices work. Now only USB keyboard is not working. I have to choose 'Ask Me Later' option every time I strats my system to make the USB devices work.

How can I solve this issue fully ?
