The current well known methods are:

1) udev/hotplug. It can create device nodes and symlinks based on the
capabilities and IDs of an input device.
1a) HAL. It has all the info from hotplug as well.
2) open them all and do the capability checks / IDs yourself.
3) (obsolete, deprecated) parse /proc/bus/input/devices, which
lists all the input devices

4) sysfs - all capabilities, IDs, etc for input devices exported there as well.
