[ARMedslack] R: R: R: R: Trouble with udev on busybox based system

Mon May 9 13:32:57 UTC 2011

Loking with more care at the verbose outout of udevd I found that things start to go wrong when this is issued:
util_run_program: '/sbin/modprobe -v usb:v4586p1026d0050dc00dsc00dp00ic08isc06ip50'

I tried at a command prompt and I get no error but also no module is loaded.

I'm not actually sure what this should load because there is no module named just "usb" and I can't find any alias with that either.
