35 .Nd SigmaTel STIr4200-based USB-IrDA bridge support
38 .Cd "irframe* at ustir?"
42 driver provides support for USB-IrDA bridges based on the SigmaTel STIr4200.
43 The driver is known to work with the following adapters:
45 .Bl -item -offset indent -compact
47 .Tn Mars II 740 USB IrDA Adapter
50 Access to the IrDA device is through the
67 .An David Sainty Aq David.Sainty@dtsp.co.nz .
69 The STIr4200 cannot notify the driver when it has received data, instead it
70 has to be continuously polled. This driver polls (when idle) at a fairly low
71 rate of 10 times per second, which means that system performance is not overly
72 affected by rapid polling, but latency is fairly high.
