UBTBCMFW(4) FreeBSD Kernel Interfaces Manual UBTBCMFW(4)
NAME
ubtbcmfw - Firmware driver for Broadcom BCM2033 chip based Bluetooth USB
devices
SYNOPSIS
To compile this driver into the kernel, place the following line in your
kernel configuration file:
device ubtbcmfw
Alternatively, to load the driver as a module at boot time, place the
following line in loader.conf(5):
ubtbcmfw_load="YES"
DESCRIPTION
The ubtbcmfw 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.
The ubtbcmfw driver creates three fixed endpoint device nodes.
The control transfers can only happen on the control endpoint which is
always endpoint 0. Control requests are issued by ioctl(2) calls.
Only incoming transfers are supported on an interrupt endpoint. To
perform I/O on an interrupt endpoint, read(2) should be used. All I/O
operations on an interrupt endpoint are unbuffered. Interrupt endpoint
is always endpoint 1.
Only outgoing bulk transfers are supported on a bulk endpoint. To
perform I/O on a bulk endpoint, write(2) should be used. All I/O
operations on a bulk endpoint are unbuffered. Outgoing bulk endpoint is
always endpoint 2.
The control endpoint (endpoint 0) handles the following ioctl(2) calls:
USB_GET_DEVICE_DESC (usb_device_descriptor_t)
Return the device descriptor.
FILES
