Hi,
I have a problem with an eGalax touch screen controller connected on a
VIA UHCI controller together with my own hardware. Sometimes when I
disconnect my own device, the eGalax controller gets disconnected as
well and immediately re-enumerates. This leads to a new assignment of a
event number which then screws my X server, as I set it up to listen
to /dev/event0.
Attached is a snipet of my syslog.
Any comments? I'd even be happy with a workaround like telling my X
server to "listen" to every /dev/event* device for now.
Oh, I was just about to forget: vanilla kernel 2.6.8.1 (plus two
modules).
Thanks,
Axel

[ the touch screen gets disconnected, but why? (the device has not been
touched
(even though it is a touch-screen ;-) )) ]
