SYNOPSIS

9       usb-devices

DESCRIPTION

13       usb-devices  is  a  (bash)  shell  script  that  can be used to display
14       details of USB buses in the system and the devices connected to them.
15
16       The output of the script is similar to the usb/devices  file  available
17       either  under  /proc/bus  (if  usbfs  is  mounted),  or under /sys/ker‐
18       nel/debug (if debugfs  is  mounted  there).  The  script  is  primarily
19       intended to be used if the file is not available.
20
21       In  contrast  to  the  usb/devices  file, this script only lists active
22       interfaces (those marked with a "*" in the usb/devices file) and  their
23       endpoints.
24
25       Be  advised  that  there  can  be differences in the way information is
26       sorted, as well as in the format of the output.

38       /proc/bus/usb/devices
39              Location  where  the  usb/devices file can normally be found for
