Serial device as input

[ymmengin]

Hello,

I'm trying to get data from a USB serial device on a RPi. It’s a QK-A021 USB AIS receiver dongle from Quark-elec.

I got a list of devices using:
$ AIS-catcher -l
AIS-catcher (build Dec 6 2025) v0.65-0-g096fdde2

2: Serial, USB Serial, SN: usb-STMicroelectronics_STM32_Virtual_COM_Port_6D8A54695551-if00
3: Serial, USB Serial, SN: usb-u-blox_AG_-www.u-blox.com_u-blox_7-_GPS_GNSS_Receiver-if00

The device I'm interested in is a QK-A021 USB AIS receiver. It's listed as # 2 Serial. So I added to my working config:
-e 38400 /dev/serial/by-id/usb-STMicroelectronics_STM32_Virtual_COM_Port_6D8A54695551-if00
I also tried: -e 38400 /dev/ttyACM1
This results in AIS-catcher giving an code=exited, status=255/EXCEPTION

My config is as follows:
-d 00000162
-e 38400 /dev/serial/by-id/usb-STMicroelectronics_STM32_Virtual_COM_Port_6D8A54695551-if00

Any ideas? Thanks!
