Hi all. I'm having difficulty with my Giga-Byte GA-SINXP1394 mother board and it's built in SiS 7001 USB controllers. I get the drivers on just fine, and Device Manager states it's working ok. I have 2 USB Hubs (a Stratitec and a GE) and when plugged in they will try to recognize and then become a Unknown Device. I can only assume that this is a software problem as I was using the Stratitec hub before successfully. I'm not sure if there was an update to XP that messed with it, or if there is something wrong with the 2.0 controller. Other devices seem to work fine in the port, so I'm hesitant to say it's fried. Anyone have any suggestions or answers? I'd appreciate any help. Thanks!
