so, that's yet another another request for more open
permissions on USB devices plugged in to the laptop.

i would like to propose giving user-level read/write access to any
USB device which isn't an auto-mounted filesystem. perhaps an easier
rule would be, any non-storage USB device.
can anyone think of reasons that this would be unacceptable? (i assume,
but don't know, that this would not be hard to implement.
