I am having a problem using my USB keyboard (MS Natural) and mouse (MS
Intellimouse) with my ATEN Miniview II KVM switch after upgrading to RH
7.2. It worked without problems in RH 7.1 on both connected Linux boxes
and on Win2K box.
Problems on the OHCI machine:
After the upgrade, the OHCI box (SuperMicro S2QE6) is fine when directly
connecting the keyboard and mouse. /var/log/messages reads:
Jan 29 18:13:33 box_o rc.sysinit: Initializing USB controller

When keyboard and mouse are connected through the KVM switch, <cat
/proc/bus/usb/devices> gives:

On the UHCI machine:

Any ideas on how to get the switch to work?
Thanks,
