    I thought it was "usbfs"... Hmmm looking in a 2.4.23
    Doc../usb/proc_usb_info.txt document:

    **NOTE**: If /proc/bus/usb appears empty, and a host controller
              driver has been linked, then you need to mount the
              filesystem. Issue the command (as root):

          mount -t usbfs none /proc/bus/usb
          ...

    **NOTE**: The filesystem has been renamed from "usbdevfs" to
              "usbfs", to reduce confusion with "devfs". You may
              still see references to the older "usbdevfs" name.

    I guess both work but it is migrating to usbfs. <shrug>
