Thread: Touchscreen Not Working After Hibernation

maybe try a different version driver.. i dunno.

I recently had a similar problem with my new indash screen, none of the drivers would let the touchscreen work after hibernation unless i unplugged and re-plugged the USB cable. XP-SP2 didn't help either.

I ended up doing someting similar to this with the devcon utility ... monitoring the system for a power resume and then basically emulating a physical replug of the cable. Works great

the included Worcol software wouldn't install, so I used touchkit (egalax) and its working fine now.

BUT.. When I go into hibernation, then come back out of it.... the touchscreen doesn't work.

I have to close the touchkit software, then reopen it. Is there a fix for this? ANYONE!!!!!!

Is it througha hub? I have had this problem in the past. If it is through a hub try in directly into MB.

Will try that for sure Ninja, I'll let you know tomorrow if that works... I haven't tried unplugging/plugging in the cable, only restarting the software.... so thats interesting.

I figured out the problem, just need to close and reopen TouchKit - close before hibernation, reopen after...

Ok, so I got the opening of TouchKit problem fixed, BUT, I need something that can close it before going into hibernate, any suggestions?

Download this util: http://www.rpi.edu/~desimn/suspendtrigger/index.html

You will need to run devcon disable USB/vid_XXX*
on shutdown

and devcon enable USB/vid_XXX* on resume.

You need to get the USB device name of your touchscreen first by doing a devcon status *

You will obviously need to download devcon first - do a search.

Works well!

Although unplugging/plugging in the cable works, it's not necessary, isn't there a way to automatically close the TouchKit software when going into hibernation?

I'll still try devcon, I have it installed, but I can't get any of those scripts to work, is there a way to do it without the shutdown code? Just recognize hibernate and disable the USB device, then enable when coming back?

Sure, download a killtask app (that can kill a process via a command line switch) use that hibernate trigger to run it, and then restart it.. same idea as running devcon.

Thats kind of what I had in mind, just no idea how to do that, lol... Basically I need a vb script that tells the app to kill the task (touchkit).. then have hibernate trigger run that vb script when going into hibernate... Any idea what killtask software/vb script I can use?

Also, could you use a sendkeys script to just press "alt+F4" in the TouchKit window, I have no idea how this stuff works, just an idea though.

I REALLY appreciate the help guys, this project would be impossible without it.
