.Sh NAME
.Nm ubtbcmfw
.Nd Firmware driver for Broadcom BCM2033 chip based Bluetooth USB devices
.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 request 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 a 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 enpoint 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.
.El
.Sh BUGS
Most likely.
Please report if found.
