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 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 get 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:
| Code: |

xinput --list shows:
| Code: |
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Broadcom Corp id=11 [slave pointer (2)]
⎜ ↳ PS/2 Mouse id=13 [slave pointer (2)]
⎜ ↳ AlpsPS/2 ALPS GlidePoint id=14 [slave pointer (2)]
⎜ ↳ Beijing IRTOUCHSYSTEMS Co.,LtD Optical TouchScreen id=9 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]

↳ Broadcom Corp id=10 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=12 [slave keyboard (3)]
↳ Laptop Integrated Webcam id=8 [slave keyboard (3)]

and the details for the device is (xinput --list 9):
| Code: |
Beijing IRTOUCHSYSTEMS Co.,LtD Optical TouchScreen id=9 [slave pointer (2)]
Reporting 3 classes:
Class originated from: 9
Buttons supported: 5
Button labels: Button Unknown Button Unknown Button Unknown Button Wheel Up Button Wheel Down
Button state:
Class originated from: 9
Detail for Valuator 0:
Label: Abs X
Range: 0.000000 - 4095.000000
Resolution: 10000 units/m
Mode: absolute
Current value: 256.000000
Class originated from: 9
Detail for Valuator 1:
Label: Abs Y
Range: 0.000000 - 4095.000000
Resolution: 10000 units/m
Mode: absolute
Current value: 257.000000
|
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.
