[SDL] Any reported problems with SDL and USB adaptors for PSX, Genesis?

[Stephen Anthony]

Has anyone been having any problems with SDL 1.2.12 and USB adaptors for 
Playstation and/or Genesis controllers?  I've been getting a number of 
reports on these devices, but I still haven't narrowed the problem 
down.  The reports tend to be with WinXP.  The problems are usually 
that SDL doesn't register button presses; axes seem to be fine.

Thanks,
Steve
