Make sure that USB_STREAM_TIMEOUT_MS is set in the MassStorageHost ClassDriver demo, so that slow devices don't time out the data pipe. Increase pipe timeout in both MassStorageHost demos to 5 seconds to account for the really slow devices.
Fix TeensyHID bootloader not properly shutting down the USB interface to trigger a disconnection on the host before resetting the AVR.
