The plugin will not help with this, but you know the device names that you
are looking for, you can just do something like this:

  pattern := '*usb*'.
  (FileDirectory on: '/dev') fileNames
        select: [:e | pattern match: e]
        thenCollect: [:e | '/dev/', e]

I think it's fixed in the latest Subversion sources now.
