Constructor & Destructor Documentation

__request_type()

dx::usb::__request_type::__request_type ( dx_enum_prefix recipient  recipient, dx_enum_prefix type  type, dx_enum_prefix direction  direction  )

inline

Todo:

remove constructor when C++20 becomes available constructor only needed to initialze _reserved bitfiled (which should be anonymous)
