BSD has the usbhid interface, which uses events as well. It's implemented in 
xf86-input-joystick's backend_bsd.c file and it's pretty generic (here of 
course trimmed for joystick use).
Of course the interface is BSD-only (don't know about Solaris) but if the 
interfaces are somewhat compatible one could of course thing about wrapping 
it in the server, like the joystick driver does for itself.
