Description brianchad@westnet.com.au 2009-05-14 02:25:37 EDT
Description of problem:

No permission to use serial port even though user is a member of uucp group.

only can use serial port as root.

I am guessing udev is the place to put this bug.


Version-Release number of selected component (if applicable):
udev-141-3.fc11.x86_64

How reproducible:
always


Steps to Reproduce:
1.add user to uucp group and relogin.
2.try to use serial port as user.
3.try to use serial port as root
  
Actual results:

root can use serial port, but user cannot, even though user is a member of uucp group


Expected results:

user should be able to use serial port if member of uucp group .. ie to use minicom etc
