.SH NAME
|
|
usb-devices \- print USB device details
|
|
.SH SYNOPSIS
|
|
.B usb-devices
|
|
|
|
.SH DESCRIPTION
|
|
.B usb-devices
|
|
is a shell script that can be used to display details of USB
|
|
buses in the system and the devices connected to them.
|
|
|
|
The output of the script is similar to the \fIusb/devices\fP file
|
|
available either under \fI/proc/bus\fP (if usbfs is mounted), or under
|
|
\fI/sys/kernel/debug\fP (if debugfs is mounted there). The script is
|
|
primarily intended to be used if the file is not available.
|
|
|
|
In contrast to the \fIusb/devices\fP file, this script only lists
|
|
\fIactive\fP interfaces (those marked with a "*" in the \fIusb/devices\fP
|
|
file) and their endpoints.
|
|
|
|
Be advised that there can be differences in the way information is sorted,
|
|
as well as in the format of the output.
|
|
|
|
.SH RETURN VALUE
|
|
If sysfs is not mounted, a non-zero exit code is returned.
|
|
|
