.Dd September 5, 2014 .Dt ULED 4 .Os .Sh NAME .Nm uled .Nd USB LED driver .Sh SYNOPSIS To compile this driver into the kernel, place the following lines into your kernel configuration file: d -ragged -offset indent .Cd "device uled" .Cd "device usb" .Ed

p Alternatively, to load the driver as a module at boot time, place the following line in .Xr loader.conf 5 : d -literal -offset indent uled_load="YES" .Ed .Sh DESCRIPTION The .Nm driver provides support for the Dream Cheeky WebMail Notifier device.

p Subsequently, the

a /dev/uled0 device can be used by userland applications. .Sh IOCTLS The following .Xr ioctl 2 commands can be performed on

a /dev/uled0 , which are defined in n dev/usb/uled_ioctl.h : l -tag -width indent t Dv ULED_GET_COLOR The command returns LED colors with values for RGB. This .Xr ioctl 2 takes the following structure: d -literal struct uled_color { uint8_t red; uint8_t green; uint8_t blue; }; .Ed t Dv ULED_SET_COLOR The command sets LED colors with values for RGB. It uses the same structure as above. .El .Sh FILES l -tag -width ".Pa /dev/uled0" -compact t Pa /dev/uled0 blocking device node .El .Sh SEE ALSO .Xr ohci 4 , .Xr uhci 4 , .Xr usb 4 .Sh AUTHORS .An -nosplit The .Nm driver was written by .An Kevin Lo Aq Mt kevlo@FreeBSD.org .
