USB device mode doesn't work reliably, and FSL was never able or willing to come up with a solution. When this issue happens, the USB device controller not only returns a truncated packet to the gadget driver, but doesn't report URB completion to the host either. The host never gets an URB complete event, so you will see first a delay, and then the host resets the device. The issue can be reproduced with massive writes to a mass-storage device.
