Joysticks can be a bit of a hassle to get working in Linux. Not because they are poorly supported, but simply because you need to determine which modules to load to get your joystick working, and it's not always very obvious!
Determining Which Modules You Need
For an extensive overview of all joystick related modules in Linux, you will need access to the Linux kernel sources -- specifically the Documentation section. Unfortunately, pacman kernel packages don't include what we need. If you have the kernel sources downloaded, have a look at
Documentation/input/joystick.txt. You can browse the kernel source tree at kernel.org by clicking the "C" (current changesets) link, then clicking the "tree" link near the top. Here's a link to the Documentation from kernel 220.127.116.11.
Some joysticks need specific modules, such as the Microsoft Sidewinder controllers (
sidewinder), or the Logitech digital controllers (
adi). Many older joysticks will work with the simple
analog module. If your joystick is plugging in to a gameport provided by your soundcard, you will need your soundcard drivers loaded - however, some cards, like the Soundblaster Live, have a specific gameport driver (
emu10k1-gp). Older ISA soundcards may need the
ns558 module, which is a standard gameport module.
As you can see, there are many different modules related to getting your joystick working in Linux, so I couldn't possibly cover everything here. Please have a look at the documentation mentioned above for details.
Loading the Modules
You need to load a module for your gameport (
cs461x, etc...), a module for your joystick (
adi, etc...), and finally the kernel joystick device driver (
joydev). Add these to your
/etc/rc.conf, or simply modprobe them. The
gameport module should load automatically, as this is a dependency of the other modules.
Testing Your Configuration
Once the modules are loaded, you should find a new device:
/dev/input/js0. You can simply
cat the device to see if it works - move the stick around, press all the buttons. I found my Logitech Thunderpad Digital had two buttons that weren't working with the
analog module. After reading some docs, I saw there was a specific
adi module for this controller. The moral of the story is, if it doesn't work the first time, don't give up, and read those docs thoroughly! I couldn't get anything working at all until I found that documentation.
You need to get USB working, and then modprobe your joystick driver, which is
usbhid, as well as
If you use a usb mouse or keyboard,
usbhid will be loaded already and you just have to load the
