Hello, again!
Well, with lots of debugging enabled, I got to some more details about the
non working DMC TSC-10 USB Touchscreen:
(see also: http://lkml.org/lkml/2007/6/26/228 )
Whenever I plug in the TSC-10 I get the following output
hub 3-0:1.0: state 7 ports 4 chg 0000 evt 0004

And when I unplug it, it cleans up the device properly:

usb 2-1: uevent

Any ideas of what's wrong here before I have to start to
dig deeper in the source?!
The touchscreen controller chip is a TSC-103 088 F3J0
it has no EEPROM attached. (which should be optional to save
calibration data)
The USB controller is a Philips ISP1563BM PCI Host Controller
DateCode April-2006.
The same problem appears with 2.6.21.5 and 2.6.20.1-ubuntu-something
on x86 platform.
