Hi there!
I have a DMC TSC-103 Touchpanel controller chip on an ISP1563 Philips USB Host
controller
on PCI on MPC8540 embedded PowerPC.
USB is working fine on that machine. USB Mouse and Keyboard works on X.
But I cannot get the touchscreen to talk to userspace, something like
/dev/input/touch or /dev/input/eventX isn't created.
Here are lots of details:

The Jan 1 1970 is correct (my RTC chip is broken).
The usbdev3.2_ep?? is my TSC-10.

Without anything plugged to USB.

When I plug in a M$ IntelliMouse thingy.
(ts0 belongs also to the mouse... ?)
I cannot hotplug/unplug the Touchscreen controller because
it's built-in. :-(

$ udevinfo -a -p /sys/bus/usb/devices/3-2/
Udevinfo starts with the device specified by the devpath and then
walks up the chain of parent devices. It prints for every device
found, all possible attributes in the udev rules key format.
A rule to match, can be composed by the attributes of the device
and the attributes from one single parent device.

Well, it's there and it seems to work.
some udev rules say:
# Input devices go in their own subdirectory
KERNEL=="mice", MODE="0644", NAME="input/%k" SYMLINK="mouse"
KERNEL=="mouse*", MODE="0644", NAME="input/%k"
KERNEL=="event*", MODE="0600", NAME="input/%k"
KERNEL=="js*", MODE="0644", NAME="input/%k"
KERNEL=="ts*", MODE="0644", NAME="input/%k"
KERNEL=="psaux", MODE="0644"
KERNEL=="js", MODE="0644"
KERNEL=="djs", MODE="0644"
(What is js and djs?)
What is the magic udev rule to get the dmc driver (usbtouchscreen.c)
to talk to me?
Can you please give me some information how I can
get some raw /dev/input/touch or similar and
get at least some userspace program (i.e. calibrator, see below).
But some cat <devicename> would make me also happy.
Second construction area is X:
I've read
http://linux.chapter7.ch/touchkit/mini-howto.txt
already and built the touchkit calibrator.c successfully.
Whenever I run
$ Xorg &
$ export DISPLAY=0:0
$ calibrator /dev/usbdev3.2_ep{00,81}
Cannot open device file!
$ calibrator /dev/input/{mice,mouse,ts0}
gets me the calibration screen, but no input.
I added some more debugging information to calibrator, so it
prints at least some events when I use the mouse driver's
device here.
Whenever I use the xorg-xf86-input-dmc driver I get from Xorg:
(EE) DMC-Touch reset error
The xorg-xf86-input-evdev driver delivers some.
(EE) PreInit returned NULL for "touchscreen"
Of course... because /dev/input/ts0 is just not the TSC-10...
I've tried lots of combinations in xorg.conf:
Section "InputDevice"
Identifier "touchscreen"
Driver "evdev"
# Driver "dmc"
Option "Device" "/dev/input/ts0"
# Option "Device" "/dev/usbdev3.2_ep81"
# Option "DeviceName" "touchscreen"
Option "MinX" "1412"
Option "MaxX" "15184"
Option "MinY" "15372"
Option "MaxY" "1230"
Option "ScreenNumber" "0"
Option "ReportingMode" "Scaled"
# Option "ReportingMode" "Raw"
Option "ButtonNumber" "1"
# Option "ButtonThreshold" "17"
Option "SendCoreEvents"
EndSection
Does somebody have a xorg.conf example configuration for the TSC-10 on USB?
Thank you,
