Now i updated to the new udev, which is already in the updates tree for 
FC3 (though not at all mirrors yet). Nothing changed.

$ rpm -q udev
udev-039-10.FC3.7

I tried your recommendation, but I get:

# /sbin/rmmod ehci
ERROR: Module ehci does not exist in /proc/modules

So i looked into it, but it seems to be there:

# cat /proc/modules | grep "ehci"
ehci_hcd 32585 0 - Live 0xe0958000

# /sbin/lsmod | grep "ehci"
ehci_hcd               32585  0


So now I get to the regions of Linux resp. Fedora, about which I - as 
non professional user - do not have any knowledge anymore.
