An update on this problem I had:

I put it into someone else's Ubuntu machine on Saturday for fun. And 
it worked... Now it works again on my machine too...

It now works on a kernel compiled long ago, and a brand new 2.6.15.4. 
Normally I'd say my config was screwy, except that it also didn't 
work on an Ubuntu LiveCD either. So maybe my USB controller has gone 
dodgy, but that doesn't explain the stick suddenly working in another 
machine, and all other signs of the problem going away.

I'm happy to have the thing work again, now I'd also like to 
understand why it works again. Can anyone explain this?
