Comment 12 for bug 1550719

Brian,

I can explain this.
General requirement of upstream maintainers is to include output of 'cat /sys/kernel/debug/usb/devices'.
It is the most full source and can be run on any Linux system.

'usb-devices' output includes basically the same information. But this software is not available in all linux systems.

Output of 'usb-devices' is acceptable upstream.

It really does not make much difference which one to use. But I vote for 'usb-devices', since it is available in Ubuntu, does not require sudo and the output is a bit shorter.
