Serial Connection - Attempt to open unknown device

I’m looking for someone proficient in QGroundControl and Android serial ports. I am building QGC for a custom hardware platform and can’t make it bind to a Serial port. I have 2 serial ports in the system (/dev/ttyHS0 and /dev/ttyHS1).

Neither of ports are automatically detected and if I hardcode a device path, qserialport_android.cpp spits out “Attempt to open unknown device /dev/ttyHS0” error. I have verified ttyHS0 is located in /dev/ and it has appropriate permissions.

Has anyone experienced something similar?
