I would be happy to modify the xorg.conf file if the USB version could be coaxed into looking like a serial port. At a guess the USB panel is being picked up by the kernel input layer and mixed in with all the other mice-like pointers to appear at /dev/input/mice. Since /dev/input/mice is already mentioned in your /etc/X11/xorg.conf you're seeing it just work. Based on the USB IDs you should have a mtouchusb kernel module loaded. cat /proc/bus/input/devices gives I: Bus=0003 Vendor=0596 Product=0001 Version=0400 N: Name=3M 3M USB Touchscreen - EX II P: Phys=/input0 S: Sysfs=/class/input/input3 H: Handlers=mouse1 event3 B: EV=b B: KEY=400 0 0 0 0 0 0 0 0 0 0 B: ABS=3 Yep, that Handlers=mouse1 event3 mean that it's being mixed into /dev/input/mice. That swapped axis shouldn't be happening. Pull the kernel source for drivers/usb/input/mtouchusb.c and make sure the exact model is listed, as there's a note in there about the Y axis handling that makes me wonder if you don't have hardware with a feature corrected. If that still sucks you'll need to swap the axises in X11 as the input layer doesn't allow such niceness.

Re: [SLUG] Microtouch USB touch screen X/Y axis swapped
Just following up with more info. It seems there's been a fair bit of consolidating work in this area in the kernel modules between 2.6.15 and 2.6.18. In 2.6.15 the module was mtouchusb and this and others have been merged into a more generic one called usbtouchscreen kernel/drivers/usb/input/ is where they are. The good news is there is in fact a swap_xy parameter in the stock 2.6.18 kernel module and it works. The bad news is that my x and y direction is opposite to what it should be. IE move your finger left, the pointer goes right. So I added 2 more module parameters invert_x and invert_y and recompiled the module but for some reason the module isn't behaving... it's my day off so I've yet to discover whether it's my module build process or the modification I've done (ie can't test remotely). The module does load but when Xorg tries to talk to /dev/input/mouse1 it gets an open error. There seems to be some heated debate about where the calibration should happen as well. In the RS232 version it was in the xorg.conf file. Any tips on inverting X and Y and scaling them in the xorg.conf file appreciated.
