I have been using them for some years now. The only problem I've had 
over several kernel 2.6 versions and for over year - After boot up, the 
buttons and controls do not work.
To get them working, I have to unplug them and reinsert them, then 
everything works OK. This has been the same on both x86 and x86_64 
architectures, right up to the latest AM2 64x2 box and openSuSE 10.3 Alpha5.
I reported the problem to the USB development group early on, but got no 
reply. It seems there is some race condition that prevents them being 
properly being initialised. I also did not find out which kernel the 
problem appeared with, it seemed to have been when they changed the 
input subsystem layer, 2.6.17-ish (???).
js_demo and jstest lists them all, but they are inoperative - vaulues 
being static with control movements.
