33 .Nd Firmware driver for Broadcom BCM2033 chip based Bluetooth USB devices
39 is a firmware driver for Broadcom BCM2033 chip based Bluetooth USB devices.
40 It provides minimal access to the parts of the device required to download
45 driver creates three fixed endpoint device nodes.
47 The control transfers can only happen on the control endpoint which
49 Control requests are issued by
53 Only incoming transfers are supported on an interrupt endpoint.
54 To perform I/O on an interrupt endpoint,
57 All I/O operations on an interrupt endpoint are unbuffered.
58 Interrupt endpoint is always endpoint 1.
60 Only outgoing bulk transfers are supported on a bulk endpoint.
61 To perform I/O on a bulk endpoint,
64 All I/O operations on a bulk endpoint are unbuffered.
65 Outgoing bulk endpoint is always enpoint 2.
67 The control endpoint (endpoint 0) handles the following
