Xenarc Touchscreen powerfeed. Converting to selfpowered?
If seems the Xenarc touchscreen isnt self powered and only comes on after the screen itself has had power given to it. Is there any way of making the touchscreen selfpowered off the USB as i have my screen turn off HARD when i pull my keyout, but my computer stays on until the opus turns it off, so the computer thinks ive pulled the touchscreen usb out. WHen it comes back on i get a Duuuuu-daaaaaa as if ive pulled it back in again (which in effect i have as i turn my screen on) and it messes up any visulisation i have running.
How can i rewire the touchscreen controller so its in effect seperate from the Xenarcs power feed.
