N3700-ITX USB problems...

   Hello.

ASrock N3700-ITX mainboard, 16GB RAM, 120GB SSD(system), 2TB HDD(data), Windows 8.1 Pro 64-bit.

All drivers installed and updated to latest from ASrock site, BIOS updated to the latest one(1.5).

No matter what I do, W8 won't talk to ANY flash drive, on some of the USB2 or USB3 ports - they always just show up as unrecognised device, or with errors like 'Set Address Failed' or 'Device Descriptor Request Failed' or the like.

ALL these flash drives work just fine in other computers, including other W8.1 64-bit machines.

I tried several ideas I found on the net, such as turning off the 'Allow windows to power down this device to save power' kind of check-box in the device manager settings for the USB hubs, but no.

Other suggestions on the web say to scan for hardware changes. If I do this, the machine crashes in spectacular fashion - mouse and KB both locked up, and you can do nothing but force a reboot. If you start some music first, when this hang happens, the music turns to a horrible metallic screaching noise that you cannot silence - you have to pull the power plug to stop it, and force another restart.  You can cause this crash to happen any time you ask for a scan for new hardware - even if there are no USB devices plugged in anywhere, on any of the ports.

SOMETIMES the devices that won't talk, will talk in other USB ports, but not always. They NEVER work in some specific ports. Does not seem to be restricted to USB3 ports, as this also happens with the USB2 ports on this board.

Anyone seen this kind of problem, and can anyone offer any other suggestions for me to try?
