Not sure where to look according to your post. I still have usb problems. I have installed vb 1.5.2 and there is usb and I can enable usb but there are NO devices attached and I cannot attach them. They are "grayed out". Not sure what the problem is and I could use some help.
I've used virtualbox-ose before, but someone said they needed usb, so I tested for them - removed my virtualbox-ose downloaded the 32 bit gutsy .deb, installed it, and... I get nothing in system tools. Running 'virtualbox' doesn't do it either.
Ignore that. VirtualBox told me to run sudo ./vboxdrv setup in the /etc/init.d folder, which I forgot. I did that, rebooted, and it appeared fine in system tools
