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.
- usbmon2usbsnoop - a perl script that convert's usbmon output into usbsnoop log file format (thereby making the data compatible for use with, for example, usbreplay)
- kernel documentation
- The usbmon: USB monitoring framework article
- USBMon - an old java program that can interface with the output from the usbmon kernel module; unfinished ? see: the notes on this page and those from this article on USB snooping under Linux
- Wireshark - a more polished way to interface, via libpcap, with the usbmon kernel module's output; see the Wireshark wiki page's regarding USB: here and here
