Serial decoding: USB problem

Post by picouser3206MSO » Thu May 21, 2020 4:42 pm

I am trying to use the USB serial decding feature. I can take a capture, the decding starts, but never goes to the end of the capture. I have attached a screen shot showing the problem. The capture is a 100ms long, the USB decoding stops after 30ms. Am I doing something wrong or is this maybe a bug?

Thanks for any help!

It looks to me as if the decoding fails, whenever there is a zero length packet (in or out) on the bus. I think this is a bug in the USB decoding.
