Post subject:  USB2CAN same message on bus problem

Hi all,

I am trying to spy on my cars can bus network. I detected the correct baud rate to be 500000bps. When I initialize the device it joins the bus perfectly fine. The messages that i see on the bus are strange though - rather, one single message again and again. The car is on, so the bus should be full of messages. I triple checked the pinout at this point and it is correct. I do get a green light on the device too. Here is a screen shot of what i am seeing as to the messages. It is the exact same thing both on a linux vm and windows.

any ideas what it could be?

Thanks,
Damian

Did you "detect" the baudrate or did you use the proper one as specified by the manufacturer?
