So I have a Xenarc 700TSV and I too am having a USB issue with it. I have been having my system hang on occasion, which is a Intel GLY2A with SIS video drivers. I have the latest touch software installed. I am running XP SP3.

This week: I pulled out the USB line to the screen and plugged in a mouse. My system has been rock solid (albeit a pain to use).

I don't know if this is a driver issue: or if my screen is faulty. I have an extended cord from Xenarc: and I have the resolution set pretty high: like 1024x768. The screen is powered off the 12V from my M2ATX. I also have reason to suspect my motherboard: on occasion when I boot it cannot find my harddisk. I have tried several hard disks: the disks are solid. I pass all memory tests with flying colors. I was thinking about moving to an ATOM.

I am also wondering if there is alot of USB traffic caused by the screen: maybe this is causing my southbridge to overheat.

I imagine other people have this combo: and have solid systems? What resolution are they running? Which versions of the drivers are being used? Does
