I removed the mistake in get_button_from_dbob, but the behavior of the Hold switch hasn't changed.

Ok, good to know, really confusing :). I changed it back to 48.

I did some more experimentation, and i can confirm, that it somehow works when you press and hold "<<" or ">>" while using the wheel. Unfortunatly i have no idea why.
Also those readings with the pressed buttons are not reliable, it sometimes finds scrollwheel and hold/rec and sometimes not. This is why we see the hold button flickering on and off.
I also did take a look a the datasheet, and noted that the wheel and other missing buttons are on dbop bit12 and upwards. Interestingly these dbop bits map not to a gpio port, but to some dedicated dbop pins. Which means we have to use dbop for this for sure.
Also the bits i can reliable read from the dbop are all below bit12, all higher bits are nearly always 0, so there must be something wrong with our dbop setup ? *speculating*
happy hacking.

You're able to read REC (sometimes)?

I don't think so. It's basically exactly what the OF does. Interesting that you found something in the datasheet. I didn't. Can you point me to the page?
Well, reading the wheel is pretty reliable on the Fuze. I was suprised if the e200v2 needs some special handling, but it's possible. I think a look in the OF can't hurt.

1-13-09: 1gb refurbished Clips for $9.99 + $5 shipping at woot.com; good until sold out or 24 hours, whichever is first ...
In case experimental units are needed.

Hi kugel, your buttonlight-patch (http://www.rockbox.org/tracker/task/9663#comment27741) seems to do nothing on the e200v2, I tried on clean svn and with the modified fuze button-driver.
EDIT: hmm... commited patch works really good (running r19795), good work!
