I have been fighting a ghost with listening to music on my Iphone connected to the usb port in the left saddelbag. It will play fine most of the time, but it will stop playing for no reason and give me an error message. So far I have seen "usb error while playing" and "device not supported" (not at the same time).
Is anyone else having this problem, or know how to fix it? I assume it is a setting on my phone, but can not find it, or figure out why it is so random.
