Correct, there is no HFS or HFS+ support in the N770's Linux kernel, and it'll have a different partition table type, so the kernel won't recognize it beyond the raw device.

Optimal iPod device formatting would be FAT32, since then you can use it with most recent operating systems. I'm pretty sure that the Mac OS version of iTunes, and the current era (10.x) Mac OS core has FAT32 support... since 4.4BSD already did.

Hi,
I plugged my iPod into my PC and got it to be reformatted (FAT32) using the iPod updating software (this was after a few attempts, as the PC updater failed 3 times and forced me to reset the iPod on the Mac. Once it worked, the iPod was FAT32, and as JMills predicted, the Mac as well as iTunes recognized it, and it's working fine on there.

I can now mount the iPod on the 770 and browse its contents.

Thank you all for your help/guidance.
Luis.

Since the iPod Shuffle is a powered device, would it work as a flash drive without a 5v injector?

No. (Isn't this an FAQ? It should be)

The power is required for two things:

1. to power the device itself - a self-powered device like an iPod doesn't need it for this.
2. to power the USB circuitry in the 770, and possibly the device.

To use *any* device in USB host mode with the 770 requires the 770 to be supplied with +5v up its USB socket.

HTH,

Andrew

Different question then. Is it possible to make a connector that lets the shuffle pass power to the 770 instead of the other way around (since the shuffle normally charges while plugged in, but obviously can't without the 770 passing it power), rather than building a gadget with a separate battery?

It'd depend on the device; I'd be very surprised to find a USB device which output 5V on its USB plug.
