The newer usb_control_msg_{send|recv}() API are an improvement on the
existing usb_control_msg() as it ensures that a short read/write is treated
as an error, data can be used off the stack, and raw usb pipes need not be
created in the calling functions.
For this reason, instances of usb_control_msg() have been replaced with
usb_control_msg_{recv|send}() appropriately.
