# ufm(4)

USB driver for Cypress Semiconductor FM Radio

## NAME

**ufm** – USB driver for Cypress Semiconductor FM Radio

## SYNOPSIS

**device ufm**

## 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)](/usb/4.md) and one of the [uhci(4)](/uhci/4.md) or [ohci(4)](/ohci/4.md) controllers.

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