I'm playing with the TS-7553, using the full Lenny Linux. I have a program
which reads/writes from /dev/ttyUSB0. Works great as root, but not when I try
to make queries from apache, because the default permissions of /dev/ttyUSB0
are
crw-rw---- 1 root dialout 188, 0 May 17 22:01 /dev/ttyUSB0
What's the best way to get access to this? I can chmod it to 666, but as soon
as I reboot it comes back as 660. Should I be trying to figure out udev (this
looks complicated to say the least) or perhaps add nobody (what the php script
likely runs under from apache) as a member of the dialout group (that seems,
er, dangerous).
Is there another better way?
