I just wanted to point at a new issue regarding the propsed patch to 
usb_port.h, since I didn't manage to send an e-mail to the correct 
thread :-(. The suggested change was:

Apparently this relly stops the kernel panic. BUT there seems to be a
problem with devfs, when reattaching the usb hub / devices. Permissions
set in /etc/devfs.conf do not take effect any more. Even worse, if you
do a ls -l /dev, then all devices show permissions like '0'.
