/proc/bus/usb no longer mounted?

Bug Description

VMWare monitors /proc/bus/usb/devices to find USB devices and connect them into the child OS. It doesn't use sysfs or anything else, so the removal of the usbfs on /proc/bus/usb breaks the use of all USB devices in VMWare.

Note: the original reporter indicated the bug was in package 'linux-image-2.6.15-18-686'; however, that package was not published in Ubuntu.

Not a kernel issue; mountvirtfs seems to have stopped mounting this, though there's nothing in the changelog about it.

Changed in linux-source-2.6.15:

The problem is that /proc/bus/usb is entirely deprecated; and we have nothing that will change the permissions of this.

The easiest thing I guess would be to bind-mount /dev/bus/usb over the top of it

Is it not possible for vmware to use /dev/bus/usb instead?
