[Qemu-devel] usb tablet working with linux/xfree86 guest in absolute mode

["Jim C. Brown" <jma5@umd.edu>]

The tablet works with the evtouch driver.

To get this to work in a guest:

make sure you have support for usb hid and evdev in the kernel (or as modules).

make sure you have the devices /dev/input/event0 /dev/input/event1 ...
	they might be called /dev/input/evdev0 etc

download the evtouch driver, and install the evtouch_drv.o to
	/usr/X11R6/lib/modules/input

	You can download the driver from
	http://www.stz-softwaretechnik.de/~ke/touchscreen/evtouch.html

Change the default mouse in XF86Config/xorgconfig:

    Section "InputDevice"
        Identifier "Mouse1"
        Driver "evtouch"
	Option "Protocol" "usb"
        Option "Device" "/dev/input/event0"
        Option "DeviceName" "touchscreen"
        Option "SendCoreEvents"
        Option "CorePointer"
        Option "MinX" "0"
        Option "MinY" "0"
        Option "MaxX" "32767"
        Option "MaxY" "32767"
        Option "ReportingMode" "Raw"
    EndSection

    Sample working config is at http://jma-box.student.umd.edu:8080/XF86Config-4

Now restart the X server, and it should work.

Scrolling and the middle button don't seem to be supported by the driver.
