NAME

     ufm — USB driver for Cypress Semiconductor FM Radio

SYNOPSIS

     To compile this driver into the kernel, place the following line in your kernel
     configuration file:

           device ufm

     Alternatively, to load the driver as a module at boot time, place the following line in
     loader.conf(5):

           ufm_load="YES"

DEPRECATION NOTICE

     The ufm driver is not present in FreeBSD 13.0 and later.

DESCRIPTION

     The ufm 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.

     The ufm device must be configured in the kernel, along with usb(4) and one of the uhci(4) or
     ohci(4) controllers.

     Subsequently, the /dev/ufm0 device can be used by userland applications.
