Version 2.42L from VIA, maker of the 6202 chipset Unzip, then cut/paste the path to your desired OpSys version when Windows asks for the driver. THIS ONE WORKS. The version 2.54 Soyo offers (supposedly also from VIA) DOES NOT WORK. I added this card to a Tyan with only USB 1.1 on-board (using Intel). This gives me USB 2.0 and runs a Soyo BAYone AVI 6.1 memory card drive. DO NOT DISABLE ONBOARD USB!!! Just don't plug anything into it.
