I have an Elo Touchscreen that I'm hooking up to a Debian Wheezy machine. The screen itself works great, but I'm having trouble with the touchscreen part. This is an Elo E509854 (EloTouchSystems,Inc Elo TouchSystems 2216 AccuTouch USB Touchmonitor Interface). It hooks up with 2 cables - VGA for the monitor, USB for the touch input.I have 2 identical monitors, and I had hooked one of them (not sure which one) up previously, and gone through flipping the Y-axis and calibrating the touchscreen area so that it tracked your finger correctly.The problem I'm having now is that when I run evtest, the ABS_X only outputs on approximately the top left 1/4 of the screen (it runs from ~300 on the left of the screen, to 185 in the middle). Everywhere else, I get ABS_Y only - along with MSC_SCAN, ABS_MSC, etc... just no ABS_X.When I tried calibrating anyway, the mouse tracks up and down in Y semi-OK (the calibration seems a little off), but the mouse wants to stay against the left side of the screen (or the right side if I invert the X-axis). If I move in the top-left corner of the screen, the mouse bounces left-to-right rapidly. Not sure if it's part of it, but the Y-axis seems skewed ... the readings go something like this:TOP L ~ 3400                                TOP R ~ 2500BOTTOM L ~ 600                               BOTTOM R ~ 1500Any ideas on what to try? Thanks!
