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:

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.
