Unfortunately, every phone manufacturer has their own ADB driver, so if you have multiple devices, you must have specific drivers installed on your PC for each device, which is a real pain at times.

Universal ADB (Android Debug Bridge) Driver for Windows is a simple solution for this issue. It should work on all Android phones for all versions of Windows and quite useful for ADB, Fastboot & APX. Also, it does not require that you turn on test signing or disable driver verification during installation, because it installs ClockworkMod as a trusted certificate and publisher into the local machine’s certificate store. Interested users can download Universal ADB (Android Debug Bridge) Driver for Windows XP, 7 and 8 from here. (Via)
