I found an option myself:

The usbcore-module (2.6.??) has an "usbfs_snoop" parameter, it prints out the 
debug messages I looked for. The Article [1] describes where it comes from 
and 

$> echo [1/0] > /sys/module/usbcore/parameters/usbfs_snoop

enables/disables the debug output written to /var/log/kern.log (gentoo). Maybe 
someone else finds this useful.
