# Give the RFID reader a stable name: /dev/rdm-reader

# Without this, the adapter is /dev/ttyUSB0 or /dev/ttyUSB1 depending on the
|
|
# order the kernel enumerated USB devices, which changes between reboots and
|
|
# whenever anything else is plugged in. Authenticating against the wrong reader
|
|
# is a real failure, so pin the identity here instead of hoping.

# Current rule: match by vendor:product (CH340 is 1a86:7523).
