I would use the SDL solution as last resort, as this lib status is not
guaranteed in the future.

the libusb solution is for me the most appealing even if if is more  
work.
But only if the quality of the lib is good which is still unknown  
quantity.

there is HID support in linux, but problem is with X, and that not all
kernels may have this support. dont know how many. HID support
in linux use the traditionnal /dev/....
Also opening a device in linux could conflict with Xinput and others  
beside
the separate development from windows.

the fact the DDK need registration is a problem if it  is needed to  
compile,
if those using cygwin are blocked.

Now, we need to find a X11 coder ;)

tested libusb on the mac, seem to work
