No problems in device manager. Intially after the upgrade ther were some issues but updated drivers fixed that. All though I didn't mention that when the usb ports stop working, a mouse or keyboard will still work, but not ipod, usb network adapter, EHD etc.
I don't know how to update my bios or what it means to use the same flavor of USB. Sorry, I like to pretend I know what I'm doing but clearly I don't.
