Now please see the wireshark screenshot at http://personal.educity.cz/dustin/wireshark.png . Frame 1197 is the last URB of the period, with 960 bytes only. Yet the time distance around it is again 8 ms (12.808-12.816-12.824). The expected 5 ms lag appears 2 URBs later, between frames 1201 and 1203 (12.832-12.837), all holding 1536 bytes.
Wireshark shows the URBs when they are submitted, which is in the completion handler of some previous URB. This means that the timing of the submission has no relation with its size.
Hi Clemens, thanks a lot for the clarification. Everything seems to be all right and verified :-)
Best regards,
Pavel.
