Right way to handle USB
I installed a 2.4.0 kernel with USB support last evening, and it seems to
be working fine so far. However, after getting things set-up it was
apparent that Joe User did not have rights to read & write the /dev/ttyUSBx
devices. The /dev/ttyUSBx devices are all owned by root, and the group tty.
To give Joe User access to the USB, I made him a member of group tty which
worked fine. Also, chmod 766 /dev/ttyUSB* gave the same results, but
obviously I did not have to add Joe User to group tty...
So which is the correct way to do this? Should I be making random users
members of group tty as needed, or should I just chmod the /dev/ttyUSBx to
allow any user permission at any time? Is there any inherent risk to
stability or security making random users members of group tty? IS there a
risk by opening up the permissions to the /dev/ttyUSBx ?
Thanks, Bill.
PS Boy was I surprised to find the Handspring Visor driver built right in
to 2.4.0, but still no ppSCSI drivers for things like the Trantor T-348
etc... Thought that ppSCSI was merged with the development source?
