Try running it without using systemd first.

sudo AMBEserver -i /dev/ttyUSB0 -s 460800 -d

Change the baudrate (-s) if it is not 460800 for your device.

There are also python test scripts you use to test, in the github

Like most Unix/Linux commands there is an -h flag for listing the optional flags

Hi K7VE,
Thank you very much for your answer.
I have one USB-3000 stick. I'll test it on my RaspberryPi. I'll share the results. I read that compass linux is the preferred dist. for AMBEserver. I'll try to  setup it.

I have not tested the DVSI USB-3000 stick, they're pretty expensive and I haven't purchased one but I can say that we have used the ThumbDV in applications designed for the DVSI stick and it should work but no guarantee.

Hi,
I think this can be a wrong group but I could not find any group for my
question.
Can a DVSI's USB-3000 stick work with AMBEserver? Is the DVSI's USB-3000
stick is compatible with AMBEserver software?
Any help will be appreciated.
Best Regards,
