As a simple user, I'm pretty tired of this, when using a
simple serial console for something:
$ minicom
Device /dev/ttyUSB0 access failed: Permission denied.
The device is indeed readable/writable by the group "dialout":
$ ls -al /dev/ttyUSB0
crw-rw----. 1 root dialout 188, 0 Jul 14 14:11 /dev/ttyUSB0
But that group is not maintained by anyone just installing Linux
for some simple desktop use. Just like we let udev-acl handle
media players, cameras and whatnot, let it handle modems, not to
mention the fact that these "dialouts" are often just some serial
link or irDA link, we don't really know if they are modems after
all.
