That could well be the case. Although you would think that if the VIA controller was sending the proper signals over the bus then the device would respond correctly. This is one of those cases where it helps to use a bus analyzer.I imagine that's a hardware thing rather then a software thing?
An _expensive_ hardware thing.
Anyway it's rather strange as it does some comunication and it certainly does communication with other usb devices? Is it perhaps a power thing, that the device doesn't get enough juice?
Could be, I suppose. But USB devices aren't supposed to draw more current than the port is supposed to supply. Maybe the VIA port doesn't supply the proper amount of power.
connect the usb hub to the motherboard
connect the wifi stick to the hub
connect the flash drive to the hub
connect the webcam to the hub
everything works except the wifi stick
