I accidentally disabled all the internal and external USB ports to my All in One touch screen. As a result I have no touch screen, no keyboard and no mouse control and can't get any. I pulled the CMOS battery and discharged the system but that doesn't seem to have reset it. There are only two jumpers that I can find on the board. I'm hoping one of these is a CMOS reset but I have no idea which one and I don't want to start randomly shorting things. Can anyone tell me how I reset the BIOS via the hardware? Thanks!

@Archer01, welcome to the forum.
I suggest that you go into the BIOS to do the reset:
Tap "Esc" key as the computer boots / Choose BIOS setup / Reset default settings and Exit (May be a bit different wording.).
This should do what you need.
