USB OK, but "/proc/bus/usb/.usbfs is not responding&quo

I use VBox 1.6.2 on host Ubuntu 8.04, running guest Win2k.

To make USB devices work properly I have to add the line

none     /proc/bus/usb   usbfs      devgid=1003,devmode=664     0       0

to my /etc/fstab file, as detailed in the manual, section 11.5.7 and elsewhere on this forum.

However, this throws an error in the host's file manager (I use Xfe):

Mount point /proc/bus/usb/.usbfs is not responding

What does this mean in simple terms, and what can I do about it?

Look in the FAQ, there are special solutions for Ubuntu (afaik changes in udev rules).

I think I've managed to resolve this.

Experimenting with the different steps I took to enable USB in the first place, I find that undoing one of the steps mentioned in the FAQ seems to have sorted things out - specifically, I re-commented-out the 'Magic to make /proc/bus/usb work' in /etc/init.d/mountdevsubfs.sh.

USB still works OK in the VM, and I don't get any errors when opening Xfe. Not sure if this is due to upgrades in Ubuntu, in VBox, or in my own stupidity.
