Not sure if those files are malformed, but at least it shows that the parser isn't safe on some files generated by USB2Sniffer.

Here is the backtrace of one of such crashes. One mitigation could be to drop packets that have a plen above USB's maximum packet length.
Attached to this issue is one file that cause this kind of issue.
usb2sniffer-autocapture.zip

This issue seems to happen when a USB packet has more than 512 bytes (in the above example it is 515 bytes long).
I wonder if it is USB 3-compliant to send a 1024 byte BULK transaction over a USB 2.0 differential pair if the host controller supports USB 3.
