USB Hubs for Cameras and Guiders

I recently changed PC's in my observatory and moved to 64 Bit OS.

I have noticed during imaging and focusing runs I am getting a few driver timeout errors from my main imaging camera. I have the driver in CCD Soft set to High Priority downloads but still getting these.

Just wondering what solutions others are using to connect their main imaging camera and auto guider to their PC's .

Be interesting discussion to see if there are any golden rules that seem to work.

Obvious answer is ensure separate USB cable for Guider and Camera. I will try this as well but wondering how much success anyone has had running a 12v powered USB hub on their scope connecting Guider and camera through same USB cable back to PC.

With unattended imaging I cant afford to have these timeout errors ever so looking for a robust solution.

I am even toying with idea of putting one of these mini form factor PC's that are around 6 - 7 inches long and or 5 inches wide directly on the mount.
Here a a couple:

That way cable runs are short and direct. And imaging acquisition software runs right on the PC that sits on the mount. All that needed is single Lan cable from mini PC to control remotely via Team Viewer.

How are you guys solving these issues ?
