33 .Nd Firmware driver for Broadcom BCM2033 chip based Bluetooth USB devices
35 To compile this driver into the kernel,
36 place the following line in your
37 kernel configuration file:
38 .Bd -ragged -offset indent
42 Alternatively, to load the driver as a
43 module at boot time, place the following line in
45 .Bd -literal -offset indent
51 is a firmware driver for Broadcom BCM2033 chip based Bluetooth USB devices.
52 It provides minimal access to the parts of the device required to download
57 driver creates three fixed endpoint device nodes.
59 The control transfers can only happen on the control endpoint which
61 Control requests are issued by
65 Only incoming transfers are supported on an interrupt endpoint.
66 To perform I/O on an interrupt endpoint,
69 All I/O operations on an interrupt endpoint are unbuffered.
70 Interrupt endpoint is always endpoint 1.
72 Only outgoing bulk transfers are supported on a bulk endpoint.
73 To perform I/O on a bulk endpoint,
76 All I/O operations on a bulk endpoint are unbuffered.
77 Outgoing bulk endpoint is always endpoint 2.
79 The control endpoint (endpoint 0) handles the following
