[IrDA]: Kingsun Dazzle IrDA USB driver

Browse Source 
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

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.
