here we´ve got an iMac running current linuxppc-R5 with an Elo touchscreen
attached to usb-hub by a KeySpan serial/usb adapter.
There´s a (serial) module coming with normal X11, so I guess I just have to
find the right usb-port to use in the XF86-config.
I just hope that my guess was right, or do I have to use/program a special
usb-module to add to the kernel ?
I´m curious about that because of the Kernel Messages that follow:
