Touchscreen Issues! Please Read!
This should be a sticky thread, but I'll let that to the mods to decide.
We all heard of this before, touchscreen times out, wont work anymore till reboot, or replug action is taken. There is a fix! and it has NOTHING to do with the USB power management! Be aware though that by modifying the registry you do so at your own risk, I'm just here to help you folks out on what I went through to get the xenarc touchscreen (or any other for that fact) working perfectly in XP and Vista, regardless how idle it was.
1) Open the Registry and goto the following key
*NOTE* is the USB port variable that the touchscreen is identified as. If there is more than one of them, do the following steps for each and every one.
2) For all Idle* keys, set the value to 0, should be 2 sets of idle* keys per usb port if u plugged the TS into different ports.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\U SB\VID_0EEF&PID_0001\5&3b27c391&0&1\Device Parameters\]
if thats where your keys are:
Set Idletimer, or idle*anything* to 0
do that for all usb ports the TS is or was attached to in the list, then reboot.
I tested this for 2 days straight, WITH AND WITHOUT USB HUB POWER SAVINGS! This is what everyone will need to know to fix all TS timeout issues!

Attempt to do this, keys not found...
I eagerly attempted to try this fix, but when I looked for the Idle* keys they were not there. There were only three keys in each of the Device Parameters:
Please Please Please help me figure this out if you can... It's truely driving me up the wall
Touchkit software installed
The touchkit software is installed, of course. Otherwise the screen wouldn't function at all. As stated earlier, the screen works for some amount of time between 30 seconds and 3 hours and then stops.
I have the latest build of the software that isn't in beta, I think it's 126.96.36.19925. I originally installed the beta one (v:188.8.131.523) and then uninstalled it when it started doing this problem. I think the uninstall was complete. But the version 184.108.40.20625 is definately installed now.
I will export and post the reg hive 1st thing in the morn.
