UMASS pbm at startup

[Aymeric MUNTZ (Cerbere3)]

Hi,

I have a pbm with my usb disk-key under freebsd.
When i start the system (FreeBSD 5.2) with the key already plugged, it is
not recognised. If I unplug and replug it, it is recognised.
With an other motherboard, I do not have this problem.

Is there a way to rescan for usb devices? I already tried "camcontrol rescan
all" with no success.

Thanks

Cheers

Alex
