There's a known conflict between the "brltty" (Braille support) package and the FTDI serial adapter as documented in your tutorial. I have never used USBtinyISP and haven't heard anything one way or another about that, but I assumed that's what the OP referred to.

I'm stumbling in the dark as much as the next guy on udev issues but I'm guessing that, when someone has to be root to use a serial device, it's because the device file isn't assigned to the "dialout" group. On my system, this appears to be controlled by the file "/etc/udev/rules.d/40-permissions.rule".

The section of the file that mentions this group looks like:

Code: Select all

# Serial devices
SUBSYSTEM=="tty",                       GROUP="dialout"
SUBSYSTEM=="capi",                      GROUP="dialout"
SUBSYSTEM=="slamr",                     GROUP="dialout"
SUBSYSTEM=="zaptel",                    GROUP="dialout"
KERNEL=="ttyLTM[0-9]*",                 GROUP="dialout", MODE="0660"
Perhaps this file got modified or deleted or something when the britty package was uninstalled?
