yes, it does show up as hid device. it has two usb configurations, hid 
(default) and non-hid.

there is only one small thing in the linux event system that keeps the box 
away from using _all_ of its i/o capabilities.
problem is that the linuxevent system has artificial limits imposed on how 
many buttons/led's/absolute axes a device should have at maximum. for sure im 
way above that maximum ..... another thing is that the event system by 
default does not send absolute values to the device. altough it _can_ do 
sending stuff, as you can see with led's (on the keyboard, for example), it 
refuses to do so with absolute controllers. on my page i have written a small 
text on how to tweak linux's event modules to handle that. see
