My HP-P1 came today, and I'm having a problem with the interface with my Gen 5.5 80 gig iPod.
When connected, the iPod goes straight to a screen that says "Okay to disconnect."
I have reset the iPod 10 or 15 or more times, including resets connected to the AC adapter. No change.
I called Fostex support before ordering the HP-P1, to ask if it would interface with a 5.5G. The guy said yes.
Has anyone successfully interfaced an HP-P1 with a Gen 5.5?
