Comment 10 for bug 512464

I've the same problem and since I've upgraded to Lucid, I wonder if I have to delete all the rules which are in /etc/udev/rules.d. Moreover I want to know if udev still search also in such a directory or if it can be deleted too.
Finally since I have the following rule 10-vboxdrv.rules:

KERNEL=="vboxdrv", NAME="vboxdrv", OWNER="root", GROUP="root", MODE="0600"
SUBSYSTEM=="usb_device", GROUP="vboxusers", MODE="0664"
SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", GROUP="vboxusers", MODE="0664"

which I've written to change file permission of usb device in order to use them with virtualbox, can I move it to /lib/udev/rules.d?

Thank you,
