Usbmon

USBMON

A simple tool to trace linux USB activity, using /dev/usbmon0.

By default it dumps all USB traffic. Use options:

-b### dump only bus ### -d### dump only device ### -x### exclude device ### from dump

If you don't have /dev/usbmon0 you probably need to load the driver: % sudo modprobe usbmon

And you will likely have to adjust permissions too (unless you want to run this program as root): % sudo chown $USER /dev/usbmon0
