Very odd. And unfortunately I do not know what the problem might be.
From your testing we can conclude two things:
- The controller has no problem detecting the device (the difference in the "Present" register shows that).
- Interrupts work just fine, as it can properly communicate with the card.
And since the problem is normally one of those two, I have no idea what the hell is going on here. Ricoh is also one of the Linux-unfriendly vendors so no hope of getting them to cough up some info.
We could do some silly polling hack. It isn't clean, but it might get things somewhat working at least.
