Hi Greg, I was having a quick look and it looks like visorchipset is not yet initialised and the bus is not yet registered. If you remember we had a loooong discussion in another thread "usb: ulpi: don't register drivers if bus doesn't exist", I sent a proposed patch also. For your reference: "http://www.spinics.net/lists/linux-usb/msg125368.html". I think this one is the perfect example of that case here.
regards sudip
