Definitely not a waste of time - for driver issues where people like me cannot even reproduce the thing at all (I have a ricoh controller myself, and yenta and PS/2 mice work fine together) any amount of experimentation is fine. I can only debug this by reading the source and the specs..
Reading sources and specs is how code should be developed in the first place, but especially with drivers it often turns out that there are gotchas that might not even be documented, or might just be so subtle that you don't notice them. And when it happens only on a few machines, that makes it really hard to test (provably the code is close enough to correct that it works on many machines, but equally obviously there is _something_ wrong with it).
