.Sh SYNOPSIS
.Cd "stuirda*   at uhub?"
.Cd "irframe* at uirda?"

The
.Nm
driver provides support for SigmaTels USB-IrDA bridges that nearly follow
the bridge specification:
.Pp
.Bl -tag -width Dv -offset indent -compact
.It Tn SigmaTel ST4116
.It Tn SigmaTel ST4210
.It Tn SigmaTel ST4220
.El
.Pp
Access to the IrDA device is through the
.Xr irframe 4
driver.
Before accessing it, a firmware patch must be downloaded.
At the time of writing this, it can be found at:
.Pa http://www.sigmatel.com/documents/stir4210_4220_4116_patch_files.tar.gz
.Pp
Unpack the archive with

.Fl xzf
.Ar stir4210_4220_4116_patch_files.tar.gz
.Sh SEE ALSO
.Xr irframe 4 ,
.Xr usb 4
.Sh HISTORY
The
.Nm
driver
appeared in
.Nx 5.0 .
.Sh BUGS
.Nm stuirda
needs the firmware for configuration, so it can't be loaded at kernel
startup time.
As a workaround, you can plug in the USB-IrDA-bridge after booting.
