[chirp_users] Dumb 8900 queary

As an FYI, from the dmesg info you provided:

The cable that got unplugged and plugged back in is /dev/ttyUSB1 and that's
looks like the one you should be using with chirp.

ttyUSB0, the first USB serial port that gets plugged in is getting used
by the Linux printing system CUPS.   I don't know if you actually have
a serially attached printer or if CUPS is misconfigured to use that port.

You have two USB to serial adapters on your system, one made by FTDI
and the other a Prolific PL-2303.   As others have mentioned the
name of the port is going to be dependent on the order they get plugged in
so play close attention to which is which and watch out for CUPS opening the
wrong one.

You might want to try shutting down cupsd when you are trying to
debug the radio connectivity.

Hope this helps,
--Rob

It usually adds them, in order of insertion, as ttyUSB0, ttyUSB1, etc. regardless of which USB connector they are plugged into. At least that's been my experience with the Ubuntu and Fedora distributions. I find it's very easy to get the  ttyUSBx devices mixed up if you have more than one, especially when troubleshooting a problem. An example, FWIW:
