.Sh NAME
|
|
.Nm ufm
|
|
.Nd USB driver for Cypress Semiconductor FM Radio
|
|
.Sh SYNOPSIS
|
|
To compile this driver into the kernel,
|
|
place the following line in your
|
|
kernel configuration file:
|
|
.Bd -ragged -offset indent
|
|
.Cd "device ufm"
|
|
.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
|
|
ufm_load="YES"
|
|
.Ed
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
driver provides support for the D-Link/GEMTEK FM tuner.
|
|
The USB interface chip is the common Cypress 63001, and the tuner is a
|
|
Philips TEA5757 radio chip that uses a serial interface to set the
|
|
tuner parameters.
|
|
This design is used in the D-Link DSB-R100 USB Radio.
|
|
.Pp
|
|
The
|
|
.Nm
|
|
device must be configured in the kernel, along with
|
|
.Xr usb 4
|
|
and one of the
|
|
.Xr uhci 4
|
|
or
|
|
.Xr ohci 4
|
|
controllers.
|
|
.Pp
|
|
Subsequently, the
|
|
.Pa /dev/ufm0
|
|
device can be used by userland applications.
