Overview
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.
