plug in device
attach to device node
script runs and adjusts permissions - so far so good
<some time passes>
device node is freed again
script starts
new device added
attach to device node
somebody opens device with the old permissions
script resets permissions
IIRC we discussed this very race several times already on this list.
The canonical solution is not to reuse device nodes. Unfortunately
the number space is too small.
