usbmon

From LinuxTVWiki
Jump to: navigation, search

A Linux kernel module which can snoop and output USB communications traffic. The output produced by usbmon can be examined by using utilities such as usbdump, USBMon or Wireshark.

The v4l-utils tree provides the parse_tcpdump_log.pl script to directly talk with usbmon, parsing the result into a format feasible for analysis.
