USBView is a GTK program that displays the topography of the devices that are
|
|
plugged into the USB bus on a Linux machine. It also displays information on
|
|
each of the devices. This can be useful to determine if a device is working
|
|
properly or not.
|
|
|
|
For this program to be useful, you will need to mount the debug filesystem
|
|
(debugfs). Add this line to your /etc/fstab:
|
|
|
|
debugfs /sys/kernel/debug debugfs noauto 0 0
|
|
|
|
Now a simple `mount debugfs` will make the USB info available to USBView.
|
|
|
|
The debugfs root directory is accessible only to the root user by default.
|
|
You can grant access to the USB device info (as well as the rest of the
|
|
debugfs tree) with the "uid", "gid", and "mode" mount options. For example:
|
|
|
|
debugfs /sys/kernel/debug debugfs noauto,mode=755 0 0
