Thank you Marcus,
Port option works in pc mode for most parameter setting commands, but
unfortunatly the command --port usb:001,050 --list-files is not supported in
this mode.
It seems not as easy to control SONY a7riii as Canon cameras.
Thanks,
Michael Zhang

Hui,
You should switch it to "PC Control mode".
I see there was a connect already, but not sure if this was the right USB id.
Ciao, Marcus
