I recently upgraded to the iPhone 6 and when connecting to my x930BT via the Pioneer cable to lightning adapter I receive the following error message " USB flash drive was disconnected for device protection. Do not connect this USB flash drive to the unit. To restart USB, restart the unit."

The interesting thing is that I had the same setup with my iPhone 5, Pioneer 30 pin cable to Apple lightning adapter and it worked flawlessly.

Is anyone else experiencing this issue? Any ideas?

Really annoying that my head-unit may be a paperweight. 

Hey buddy, having the same issue here. 
See this thread, I'm hoping their solution works
