P5Q3 Deluxe -- internal USB ports stopped working

[MikeSp]

Although ALL external USB ports work great, the four internal motherboard USB ports will provide power for the front USB connections on the case and multi-card reader connection but cannot read data and there are four yellow bangs for them in Device Manger in Vista 32 bit.

I tried plugging in a spare multi-card reader, but same end result -- power but no data.

I deleted the drives with bangs in device manger so that Vista would reload the drivers, but the following error is shown in device manager -- any thoughts as what to do next -- everything else works great (Q9550 CPU, 4 GB Corsair memory and no OC'ing of anything with 1333 FSB).

Thoughts/opinions/solutions???

Thanks,
