Hello everyone, Recently I've finished the work to add support for reading usbdump file formats. I was stuck in handling the non-regular format of the dumped file: several records are grouped as a black, and a length field is added in the beginning of the block. I managed to solve this by using a private field in a struct of wiretap library. The solution is very simple in fact, but still a lot of time was wasted due to my unfamiliar with the wireshark internals. I will work on adding dissection support next, this park of work is more important. Best regards, Jie Weng
