You should look at the descriptors using USB Prober. That will tell you the capabilities of the particular iPod you are looking at.

However I think you're wasting your time. I believe iPod Audio sample info goes though the licensed IAP interface.

Moi !

I am trying to set sample frequency or get current sample frequency of an iPod on USB. It should be Audio 1.0 compliant.

I can do it on a USB audio 1.0 headset, but similar command is failing for iPod.

Does anybody have correct bytes to be set to get cur?

USB packet: A2 81 00 01 81 00 08 00

I use Thesycon tool to send simple commands.

Set configuration, set interface works.
