User Notes: http://wiki.linuxfromscratch.org/blfs/wiki/usbutils

Installation of USB Utils

Install USB Utils by running the following commands:

sed -i '/^usbids/ s:usb.ids:hwdata/&:' lsusb.py &&

./configure --prefix=/usr --datadir=/usr/share/hwdata &&
make

This package does not come with a test suite.

Now, as the root user:

make install

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.

Command Explanations

sed ... lsusb.py: Instructs lsusb.py where to search usb.ids.

Configuring USB Utils

The usb.ids data file is constantly being updated. To get a current version of this file, using Wget-1.16, run, as the root user:

install -dm755 /usr/share/hwdata/ &&
wget http://www.linux-usb.org/usb.ids -O /usr/share/hwdata/usb.ids

You may wish to add an entry to root's (or any other user who has write privilege to /usr/share/hwdata) crontab to automatically update the usb.ids file periodically.
