UFM(4)                DragonFly Kernel Interfaces Manual                UFM(4)

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"

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.

FILES
     /dev/ufm0  blocking device node

     FreeBSD.
