Presenting iPod as a standard USB mass storage device for in-car use?
bifter:
Hi,
I've had a look through the forums so forgive me if I've missed any threads on this topic however I haven't found an answer.
I have a new car with a head unit that supports a USB connection to any device that can be presented as 'mass storage'. It works fine with the micro SDHC card in my HTC Hero, USB sticks and so on, however when I connect my iPod (4th gen greyscale) I get something like 'Device Error - Not Supported'.
'OK' I thought, 'I'll load Rockbox on my iPod and that will work!' However it doesn't. Whenever I connect the iPod I see a picture of a USB on the iPod screen and it displays 'Multimedia mode' and then reboots. I then get the error on the head unit and the iPod displays 'OK to disconnect'. I've tried fiddling with the HID settings in the menu but that hasn't helped. I also saw a suggestion to hold down the Menu button when the plugging the USB in but that doesn't work either.
Does anyone know if Rockbox can present the iPod as mass storage or, if not, any software that will? Cheers!

You're probably running a release build (3.5.1 if it's a recent install). Those have USB disabled because rockbox doesn't handle charging ipods from USB well at all. If you install a current build, it will use the rockbox USB implementation and not reboot, but you might have problems due to this charging issue.

Thanks for the prompt reply. I've tried installing the current build (r25423-100401) and you're right, it doesn't reboot. However the error message is still returned from the head unit. Any other ideas?

You could try disabling HID, but if that helps, I'd expect the Apple diskmode to also work.
One possibility I can think of is that the head unit matches the Apple USB ids. If that's the case, you could try with a custom rockbox build with different ids. You'd have to edit firmware/export/config/ipod4g.h in the rockbox source and change USB_VENDOR_ID and USB_PRODUCT_ID

I had the same thought (that the stupid head unit is balking at known iPods), so I'd be very interested in this trial.
Question, though, is your music still in the Apple firmware created directory structure or are you using a "more sane" directory structure?
IF this build doesn't do the trick AND if you are using the Apple created directory structure the next test would be to delete the Apple directories and test if that is what the head unit is looking for.
