It works <g>

What we do is mount the usbfs filesystem on /dev/bus/usb/.usbfs, and
symlink the devices file from that into the parent directory (so
that /dev/bus/usb/devices exists).

The whole lot is then bind-mounted to /proc/bus/usb; so an application
using /proc/bus/usb sees the same tree as a fixed one.

We would fix the apps, but unfortunately we don't have the source to
VMware!
