⇱ man ufm (4): USB driver for Cypress Semiconductor FM Radio


ufm(4) 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.conf5:


ufm_load="YES"

DESCRIPTION

The 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 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.
