It seems the Xenarc touchscreen isnt self powered and only comes on after the screen itself has had power given to it.

i have my screen turn off HARD when i pull my keyout, but my computer stays on until the opus turns it off softely, 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)

SO to solve this, you need to do what i have done below. Seperate the USB touchscreen from the Xenarcs 20 Pin lead.

The following assumes you know abit about electronics and have disassembled a xenarc/gain beforehand

1# Find a spare longish USB lead with a male end on it.

2# Cut and strip back the wire to expose the inner cables Positive Negative and the two signal wires.

3#Before you unplug the cable on the back on the xenarc linking the USB touchscreen board to the xenarc 20pin connector you may want to check the continuity of which connect is which and where it goes at the end of the USB plug. Note, you will not get a electricity flow through the V+ pin on the USB controller and the USB plug as that is in effect 'blocked' until you turn the screen on (which is why i am doing this)

4# Unplug the cable that links the xenarcs 20pin board to the USB controller board. Notice there are 5 PINS on the controller board but only 4 on the plug that plugs into it. WHen you plug the connector back it ensure it is biased more towards one side than the other. (see pic at the bottom)

5# Either cut the original cable linking the USB touch board with the Xenarc's 20pin board or find the same connector from elsewhere (like i did) and solder it up based on your findings in #3

6# notice the colours of the USB leads and the little connector. These colours and positions were correct for my situation but i cannot garentee they will be the same for you. They should be if all colours are followed in USB leads but i suggest you check and double check it with a continuity tester (multimeter) first

7# Individually insulate them up then insualte the whole lot to ensure a good strong join in the cable (fragile connectiond under there)

8# triple check all connections and connect to USB controller. Notice how it is more towards one side of the connector than the other, leaving one pin not used it the recieving connector block.

9# Fire it up (not literally we hope) and test with fingers crossed

10# Admire your work

I hope some of you will find this useful

good luck

Jamie

I got an easyer way to stop the beep...

Go to control Panel, goto Sound Under sounds, Turn off the Windows Connect sound and disconnect sound.
