no luck with DMC TSC-10 touchscreen on USB
Hello!
I'm writing this to lkml since the linux-usb-users list seems to be stuck
in spam and I didn't receive an answer during the last week.
I have a DMC TSC-103 touchscreen controller on a ISP1563 EHCI/OHCI USB
controller
on PCI on an MPC8540 PowerPC. The USB controller is working fine with some mice
and keyboards.
The touchscreen itself is also working when I plug it to some other proprietary
PC. ;-)
So, the hardware is okay.
Now, the interesting part is:
When I don't add a specific rule to udev and I connect the touchscreen to an
USB port,
lsusb shows the TSC-10 as 0afa:03e8, which is correct:
$ lsusb
Bus 2 Device 1: ID :
Bus 1 Device 1: ID :
Bus 3 Device 5: ID 0afa:03e8
Bus 3 Device 1: ID :
When I add
$ cat /etc/udev/rules.d/10-local.rules
BUS=="usb", SYSFS{manufacturer}=="TSC-10 DM", NAME="input/touch"
and unplug/plug the touchscreen, I get indeed a device /dev/input/touch:
$ ls -l /dev/input/
total 0
crw-r--r-- 1 root root 13, 63 Jan 1 1970 mice
crw-rw 1 root root 253, 7 Jun 26 18:28 touch
BUT the touchscreen disappears from
$ lsusb
Bus 2 Device 1: ID :
Bus 1 Device 1: ID :
Bus 3 Device 1: ID :
Why does the device disappear from the lsusb output? *confused*
When I want to open /dev/input/touch to dump it's events to the console, it
just:
$ evdump /dev/input/touch
Cannot open device file!
Error: No such device or addres
When I connect some ImPS/2 mouse to the USB, it shows up as
$ lsusb
Bus 2 Device 1: ID :
Bus 1 Device 1: ID :
Bus 3 Device 28: ID 045e:0095 Kleinweich Corp.
Bus 3 Device 1: ID :
$ ls -l /dev/input/

value -1, type 2, code 1
value 0, type 0, code 0
value 1, type 2, code 0
value 0, type 0, code 0
[...]
...it just works.
So, how do I get a working device node when I plug the TSC-10 to USB?
How can I interface to that touchscreen's device event interface?
(I want to get it working in X as a second pointing device along with the
mouse...)
The kernel's usbtouchscreen.c should support that hardware since about 2.6.18.
I am quite sure I am missing something very basic, here...
Thank you in advance!
