[IrDA]: Kingsun Dazzle IrDA USB driver (4a1d7c25) · Commits · 戴 / test

This dongle does not follow the usb-irda specification, so it needs its own special driver. Just like the Kingsun/Donshine dongle, it exposes two interrupt endpoints. Reception is performed through direct reads from the input endpoint. Transmission requires splitting the IrDA frames into 8-byte segments, in which the first byte encodes how many of the remaining 7 bytes are used as data. Speed change is made with a control URB just like the one in cypress_m8, and it seems to support up to 115200 bps. On plugin, this dongle reports vendor and device IDs: 0x07d0:0x4100 Signed-off-by:

		Say Y or M here if you want to build support for the KingSun Dazzle
		IrDA-USB bridge device driver.

		This USB bridge does not conform to the IrDA-USB device class
		specification, and therefore needs its own specific driver. This
		dongle supports SIR speeds only (9600 through 115200 bps).

		To compile it as a module, choose M here: the module will be called
		ksdazzle-sir.
