btw: do you have problems using an usb printer and "lp" group permission like I posted to the mailing lists? I could only workaround it.

It happens here too. However, the printer device ends up in the vboxusers group, regardless of whether the printer is on during boot or started afterwards.

/etc/udev/rules.d/10-vboxdrv.rules contains:

KERNEL=="vboxdrv", NAME="vboxdrv", OWNER="root", GROUP="vboxusers", MODE="0660" SUBSYSTEM=="usb_device", GROUP="vboxusers", MODE="0664" SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", GROUP="vboxusers", MODE="0664"

I'm not familiar with the way udev rules are evaluated, but it appears that the rule that's supposed to set the printer's group to "lp" isn't being applied, for some reason.

I can further confirm that, after moving the 10-vboxdrv.rules file out of the rules.d directory and starting the printer, it ends up in the root group. If I then run `udevadm trigger' like you did, the printer switches to the lp group.

This is weird. :)

One more thing I just noticed is that the output of `udevadm monitor' when starting the printer after boot on each kernel differs greatly.
