/dev/ttyUSB?? permissions

[dsavage at peaknet.net]

I recently had to re-install FC1 on my laptop (before FC2 was released).
In the process the /dev/pilot link to my Treo 600 palm+phone.
Reconstructing that capability took me a while, since there aren't really
any good HOWTOs.

It wasn't quite as simple as soft linking /dev/pilot to /dev/ttyUSB1. I
was able to install pilot-link and connect to my Treo, but jpilot refused
to sync with it. Only when I ran

     # chmod a+rw /dev/ttyUSB??

did jpilot's sync function come back to life. Can anyone explain to me why
the original permissions on USB devices are 660 and not 666? Is this
something that should be Bugzilla'd?
