.Sh NAME
|
|
.Nm ubtbcmfw
|
|
.Nd Firmware driver for Broadcom BCM2033 chip based Bluetooth USB devices
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following line in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device ubtbcmfw"
|
|
.Ed
|
|
.Pp
|
|
Alternatively, to load the driver as a
|
|
module at boot time, place the following line in
|
|
.Xr loader.conf 5 :
|
|
.Bd -literal -offset indent
|
|
ubtbcmfw_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
is a firmware driver for Broadcom BCM2033 chip based Bluetooth USB devices.
|
|
It provides minimal access to the parts of the device required to download
|
|
firmware.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
driver creates three fixed endpoint device nodes.
|
|
.Pp
|
|
The control transfers can only happen on the control endpoint which
|
|
is always endpoint 0.
|
|
Control requests are issued by
|
|
.Xr ioctl 2
|
|
calls.
|
|
.Pp
|
|
Only incoming transfers are supported on an interrupt endpoint.
|
|
To perform I/O on an interrupt endpoint,
|
|
.Xr read 2
|
|
should be used.
|
|
All I/O operations on an interrupt endpoint are unbuffered.
|
|
Interrupt endpoint is always endpoint 1.
|
|
.Pp
|
|
Only outgoing bulk transfers are supported on a bulk endpoint.
|
|
To perform I/O on a bulk endpoint,
|
|
.Xr write 2
|
|
should be used.
|
|
All I/O operations on a bulk endpoint are unbuffered.
|
|
Outgoing bulk endpoint is always endpoint 2.
|
|
.Pp
|
|
The control endpoint (endpoint 0) handles the following
|
|
.Xr ioctl 2
|
|
calls:
|
|
.Bl -tag -width indent
|
|
.It Dv USB_GET_DEVICE_DESC Pq Vt usb_device_descriptor_t
|
|
Return the device descriptor.
