Logitech K120 Keyboard Problem

Logitech K120 Keyboard Not Working in Windows 7?

Keyboard seems dead. Typing on the keyboard does nothing. Under Device Manager there is an exclamation point next to an entry for USB Keyboard. Windows Update cannot seem to find it. No worries, it's from Logitech right? They probably have a device driver for it that you can download on there site. Uh, no. Logitech doesn't provide any downloadable software for the keyboard. What can you do now?

Solution for Logitech K120 Keyboard Missing Drivers

Find the file usb.inf on your computer and copy it into the Windows/inf folder. Restart your computer. See if your previously dead keyboard is working. Under Device Manager uninstall the device and scan for hardware changes again if necessary to refresh.
