Comment 57 for bug 507881

Yesterday, I upgraded from koala to lucid and had also boot problems. By removing the usbfs lines in /etc/fstab, the boot problems are solved. But is it normal the location '/proc/bus/usb' disappeared since upgrading?
And I am still not available to let usb working in virtualbox, before removing the lines in fstab, and after removing. Closed version of VB, I am added to the group vboxusers, and tried 'sudo hald --daemon=no'... Nothing seems to work. Does anyone have a possible sollution?
