lsbusb-osx

This is a rough port of lsusb from the usbutils package. It's taken from v007 as this was the last readily compatible version, and it drops the devices and tree flags/options as they rely on sysfs which doesn't exist in OSX.

In fact, there's probably little use to this package, but it's teaching me a few things.

I've left the original AUTHORS, NEWS and CHANGELOG files in place to avoid discrediting anyone.

Installation

...well this should be available through homebrew soon, for now if you want to install it you will need to build it. See below.

Building

I know basically nothing about C++ and it's tooling. I'm trying to stick reasonably closely to the existing build process for usbutils, so we're going to need to install a few things...

Dependencies

You will need to install autotools, autoconf and libusb. If you don't have homebrew installed, then start with that.

  $ brew install automake
  $ brew install autoconf
  $ brew install libusb

Configuring

There are a number of steps, as long as they occur in the right order everything else falls into place. I believe the reason it's so convoluted is that the generated files add platform/system independence, but I really can't tell. I could add a script to do this automatically, but I feel like there's something to be gained from seeing the chain.

  $ aclocal
  $ autoheader
  $ automake --add-missing
  $ autoconf
  $ ./configure
  $ make
  $ make install

### WTF!?

• aclocal generates some automake macros used in the automake files.
• autoheader will generate the config.h header.
• automake --add-missing will then process automake.am and generate automake.in.
• autoconf processes configure.ac and any files specified for inclusion and generates your configure script.
• Everything from that point on is vanilla.

Documentation

Like all good command-line tools, it's built in, and provides man-pages!

  $ lsusb --help
  $ lsusb ?

Roadmap

The 0.8x family of usbutils releases make use of a different byte-ordering library that moans when pushing out information about Hubs. I'd like to work out why and fix it.

Sometime after version 0.8x the project moves to using libudev to provide vendor/device information for USB IDs. In this project we'll continue to use the linux-usb list directly, so an upgrade to match 0.9x is unlikely.
