Hi,
During the last few days me and Oliver Neukum
exchanged some messages about fixing the usb-serial.c.
We came to an agreement and I made a patch
(which should be applied after 3 patches, which
were posted by Oliver on 1/2/07 at

I did try 2.4.20-pre11. After at least an hour of runtime no kernel

from 2.4.19 to 2.4.20-pre11. I will test it
