auto-figure out which device is what (main or debug)

[yarikoptic]

atm relies on the order of their appearance.

❯ lsusb -d 2e8a: | sed -e 's,Bus \([^ ]*\) Device \([^ ]*\) .*,\1 \2,g' | while read bus dev; do ser=$(lsusb -s $bus:$dev -v 2>/dev/null | grep iSerial | awk '{print $3;}'); echo "$bus $dev $ser" ;done
001 090: e6617c93e3706f29
001 089: e6617c93e3640d28

gives two different serials which could be used. We didn't find that serial anywhere under corresponding sys folder, which has otherwise the ttyACM* information:

❯ ls -ld /sys/bus/usb/devices/*/*/tty/ttyACM*
drwxr-xr-x 3 root root 0 Sep 12 11:54 /sys/bus/usb/devices/1-1/1-1:1.0/tty/ttyACM0/
drwxr-xr-x 3 root root 0 Sep 12 11:54 /sys/bus/usb/devices/1-9/1-9:1.0/tty/ttyACM1/

Solved as of 0d985e0 — the device is now auto-detected based on wiring, which spares us having to either query or keep track of serial numbers.

However, if those are needed they can more easily be obtained via MicroPython itself →
