-- * when it's closed, the device disconnects from usb.
-- *
-- * Configuration and device descriptors get written to /dev/gadget/$CHIP,
-- * which may then be used to read usb_gadgetfs_event structs. The driver

-- * or earlier; writing endpoint descriptors to /dev/gadget/$ENDPOINT
-- * then performing data transfers by reading or writing.
