I was wrong. The group 'uucp' did not include the user who was running
'minicom' which explains why I could not run minicom as a user.

But now I have another problem. I used to talk to the mobile phone
through /tty/usbACM0 but now suddenly the 'hotsync' decided to make the
phone available through /dev/ttyUSB2. 'minicom' works the same way with
the device set to /dev/ttyUSB2 but I wonder how that got changed.
'dmesg' returns

Note that I do not have the 'Handspring Visor' PDA but a mobile phone.

Any ideas?

TIA
