Introduction to USB Utils
The USB Utils package contains
utilities used to display information about USB buses in the system
and the devices connected to them.
This package is known to build and work properly using an LFS-11.0
platform.
Package Information
USB Utils Dependencies
Required
libusb-1.0.24 and Wget-1.21.1
User Notes: https://wiki.linuxfromscratch.org/blfs/wiki/usbutils
Installation of USB Utils
Install USB Utils by running the
following commands:
./configure --prefix=/usr --datadir=/usr/share/hwdata &&
make
This package does not come with a test suite.
Now, as the root user:
make install
To install the usb.ids data file,
using Wget-1.21.1, run, as the root user:
install -dm755 /usr/share/hwdata/ &&
wget http://www.linux-usb.org/usb.ids -O /usr/share/hwdata/usb.ids
The script lsusb.py
displays information in a more easily readable form than
lsusb. To find the
options, use lsusb.py
-h. One form of use recommended by the developer is
lsusb.py -ciu.
Configuring USB Utils
You should update the /usr/share/hwdata/usb.ids file periodically.
Execute the following commands, as the
root user, to create a systemd timer to update it weekly on Sundays at 2:30 A.M.
