With usbmon loaded, wireshark can capture from usbmon directly. Depending on
your distro, you may need to load usbmon manually:
modprobe usbmon
forget to mentioned, my platform is arm embedded system.
And it seems I have to get binary from my target board then feed it to
wireshark on my pc, right?
if so, how could I dump the binary from embedded target board?
Use tcpdump:
tcpdump -i usbmon1 -w out.dump
