[QUOTE="htpcoz, post: 127527, member: 13987"] Unfortunately the older drivers do not support the Dual 4 card, so no way back there for us (already tried... seems the new VIA USB chipset is not compatible with the old drivers). Funnily I had the option to buy the older version card for $30 cheaper, but avoided due to reading about many problems with the older dual cards... DOH!
