Hm, ok let's try this, unplug your RS485 adaptor and plug it in again.
Then run this in a terminal window and post maybe the last page of the output. This should give you information of the device you connected last:
dmesg | awk '/tty/ && /USB/ {print "/dev/"$10}'|tail-1

Reinstalled wheezy, didnt update to 2.8. Same error reading setup from VFD

Just noticed this. Is there any particular reason you are not using the current official debian buster ISO?
