Subject: [PATCH 28/49] USB: update documentation for usbmon
|
|
|
|
commit d8cae98cddd286e38db1724dda1b0e7b467f9237 upstream.
|
|
|
|
The documentation for usbmon is out of date; the usbfs "devices" file
|
|
now exists in /sys/kernel/debug/usb rather than /proc/bus/usb. This
|
|
patch (as1505) updates the documentation accordingly, and also
|
|
mentions that the necessary information can be found by running lsusb.

2. Find which bus connects to the desired device
