Hi,
I'm currently trying to get a Beijing IRTOUCHSYSTEMS Optical Touchscreen
to work with the usbtouchscreen kernel module (currently testing with
3.0.6).
I see that the existing module recognises a different screen from the
same vendor (Vendor 6615) so I quickly patched the module (added an
entry to recognise product version 0c20) in an attempt to use the same
routines for this screen. The device was then detected by the module and
an input device created accordingly. Unfortunately it doesn't appear to
receive any events from the screen :(
I'm looking for any advice that can help me get further, whether it's
things to try, info to read or people to talk to.
This is what the device appears like in /proc/bus/input/devices:
Code:
I: Bus=0003 Vendor=6615 Product=0c20 Version=0646
N: Name="Beijing IRTOUCHSYSTEMS Co.,LtD Optical TouchScreen"
P: Phys=usb-0000:00:1d.1-1/input0
S: Sysfs=/devices/pci0000:00/0000:00:1d.1/usb6/6-1/6-1:1.0/input/input20
U: Uniq=
H: Handlers=mouse2 event9
B: PROP=0
B: EV=b
B: KEY=400 0 0 0 0 0
B: ABS=3
The xorg log looks like this:

and the details for the device is (xinput --list 9):

Incidentally xinput --test 9 gives no output when the screen is touched,
and there is no output when cat'ing the input device files :(
Again, any advice that can help me get further, whether it's things to
try, info to read or people to talk to would be much appreciated,
Gus.
