No permission to use serial port
Last modified: 2009-05-14 07:26:56 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):
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
root can use serial port, but user cannot, even though user is a member of uucp group
user should be able to use serial port if member of uucp group .. ie to use minicom etc
