ULED(4) BSD Kernel Interfaces Manual ULED(4)NAME
uled -- USB LED driver
SYNOPSIS
To compile this driver into the kernel, place the following lines into your kernel configuration file:
device uled
device usb
Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):
uled_load="YES"
DESCRIPTION
The uled driver provides support for the Dream Cheeky WebMail Notifier device.
Subsequently, the /dev/uled0 device can be used by userland applications.
IOCTLS
The following ioctl(2) commands can be performed on /dev/uled0, which are defined in <dev/usb/uled_ioctl.h>:
ULED_GET_COLOR
The command returns LED colors with values for RGB. This ioctl(2) takes the following structure:
struct uled_color {
uint8_t red;
uint8_t green;
uint8_t blue;
};
ULED_SET_COLOR
The command sets LED colors with values for RGB. It uses the same structure as above.
FILES
/dev/uled0 blocking device node

UFM(4) BSD 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
SEE ALSO ohci(4), uhci(4), usb(4)AUTHORS
The ufm driver was written by M. Warner Losh <imp@FreeBSD.org> for FreeBSD.
