Hello,
I just upgraded the kernel on a system which has 4 USB modems
(US Robotics 56K Voice/Fax modems). The modems were recognized and
worked under 2.4.6 but under 2.4.10 they are not recognized and I get
and error that no driver claims them. Further testing indicates that
they are recognized under 2.4.9 but broke sometime between then and 2.4.10.
Here are the syslog USB messages from 2.4.9 (working):
