beside installing the Raid Matrix driver...did you install the latest "Intel INF" drivers?

have you checked the "device manager" to see if there are yellow exclamations which would show that the USB devices were not working?..if this is the case, delete all those entries and then reboot to see if they install properly.

what bios version are you using?...if you are using bios 10 (original shipping bios), i would recommend upgrading to '11' official bios.

have you checked in the bios to see if the USB device is "enabled"?...by default it is enabled but it is always good to check.

if all the above is checked and accomplished, i would say the board has a defective USB hub chip...RMA time then!
