Other minor hassles are that one is ver 1FP3-25 and the other is ver 1FB297; since he wants both radios the same, that’s not a problem, cut and paste from one img to the other and it’s done
The 1FP3-25 radio is a radio with 3 power levels (similar to a Baofeng BF-F8HP). The radio with 1FB297 is a radio with 2 power levels (similar to a Baofeng UV-5R).
First error: access to USB0 denied (or words to that effect) chmod 777 /dev/usb0 fixed that.
The better thing to do would have been to add his "user" to the "dialout" group as described on the "Running under Linux" page.
Second error: Ubuntu failed to communicate with radio. 'serial' object has no attribute 'settimeout'
Sounds like you may not running the latest CHIRP. Did you add the repository and install CHIRP as described on the "Running under Linux" page or did you make the mistake of installing from the Ubuntu software manager?
