I have this USB-CAN analyzer: https://www.seeedstudio.com/USB-CAN-Analyzer-p-2888.html
When I try and run the Can converter self test as described here: https://github.com/SeeedDocument/USB-CAN-Analyzer/blob/master/res/Document/2.USB%20-%20CAN%20converter%20self-test.pdf
I see send data but no receive data.
Is it possible I have a defective unit? Does anyone have any suggestion as to what I might do to get this to work?
