FS#12303 - iPod Video USB broken since r30546

Since r30546 my iPod Video does not connect via USB when running rockbox. The emergency diskmode works fine, r30545 works as well.

Rolling back r30546 and r30549 against current svn (r30622) solves the problem.

I tried all my PortalPlayer 502x targets. sa9200 wouldn't boot so I couldn't check but other than that the other three would connect just fine.

So, I wonder what's up there with video.

Andree Buschmann commented on 2011-10-01 07:44

Can I give any more details which might help to understand the cause?

Some detail I did not mention so far: If I connect USB rockbox switches to the USB-screen. So, rockbox recognizes the USB-connect. But there is no USB-connection established, there is no new drive available under windows.

Does this do anything to fix the issue?

Edit: reading your comment that showed up while making the patch, I'm guessing "no".

Hmmm…details. Is it just the computer/OS or something? I feel like there's some silly oversight.

Andree Buschmann commented on 2011-10-01 08:05

Your patch doesn't fix it.

Some more details: OS is Windows7.

Michael Sevakis commented on 2011-10-01 08:07

Oh, and is it just the iPod Video or any other iPod too?

Andree Buschmann commented on 2011-10-01 08:11

My iPod nano 2G works fine at r30586.

Maybe this one! Tries a static buffer instead of using the audio buffer.

No effect.

Michael Sevakis commented on 2011-10-01 09:05

ok, gotta think. so far, video is the only one confirmed to be affected as such.

Bertrik Sikken commented on 2011-10-01 10:44

I can check on the ipod nano 1g (PP based) as soon as I get back home again (tomorrow)

Andree Buschmann commented on 2011-10-01 13:22

This patch fixes the issue. I am not sure about impacts though…

Condensed patch.

Michael Sevakis commented on 2011-10-01 19:39

@Andree: the v04 patch with one line also works by itself, without the reversion of v03 (which I don't think we want since we know it's not a reliable host detection method)?

Andree Buschmann commented on 2011-10-01 20:11

v04 works as stand-alone patch. v03 was just the first quick shot, I could reduce it to the single one line in v04.
