Fails while parsing URB_INTERRUPT out

[sbonnick]

Hi. Just started using your tool to see if it will work for me. ran into a issue "ERROR: packet 8". I belive this corresponds to the 8th frame in wireshark, I have attached my wireshark log output. I'm using this in windows test.pcapng.txt .

I am still learning more about USB communication, but Looking at this thread, I wonder if the problem is in Wireshark-windows all URB info is "URB_INTERRUPT" with either "in" or "out" direction. where on Linux it may show up as "USB_SUBMIT" or "USB_COMPLETE"

Thank you for attaching sample data. I'll take a look soon

Yes, they are different, but Windows and Linux is handled separately and in theory should account for this. However interrupt support in general isn't well tested. I'll look over your data and add it to the test suite as appropriate

Awesome Thanks.

Here is also the error log.

ah ok this was known to maybe be problematic:

    def processBulkCompleteIn(self, dat_cur):
        # looks like maybe windows doesn't report the request size?
        # think this is always 0
        assert self.submit.urb.data_length == 0

anyway will take a look

is there any progress regarding this issue?

thanks :D
