Re: DRIVER NEEDED: Medion md86248 (Windows 7) [USB]
This device does not require any driver in Windows 7 / Vista / XP. It's a plug and play device providing you plug it into a working USB 2.0 port.
All support is provided by the OS with SP2 (or higher) installed. Without the service packs installed you will only get USB 1.1 compatibility.
Also, be sure to check in BIOS setup to insure that USB is ENABLED.
