help
Say Y or M here if you want to build support for the KingSun/DonShine
DS-620 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 speed only (9600 bps).
To compile it as a module, choose M here: the module will be called
kingsun-sir.

* Description: Irda KingSun/DonShine USB Dongle

*****************************************************************************/
/*
* This is my current (2007-04-25) understanding of how this dongle is supposed
* to work. This is based on reverse-engineering and examination of the packet
* data sent and received by the WinXP driver using USBSnoopy. Feel free to
* update here as more of this dongle is known:
*
* General: Unlike the other USB IrDA dongles, this particular dongle exposes,
* not two bulk (in and out) endpoints, but two *interrupt* ones. This dongle,
* like the bulk based ones (stir4200.c and mcs7780.c), requires polling in
* order to receive data.
* Transmission: Just like stir4200, this dongle uses a raw stream of data,
* which needs to be wrapped and escaped in a similar way as in stir4200.c.
* Reception: Poll-based, as in stir4200. Each read returns the contents of a
* 8-byte buffer, of which the first byte (LSB) indicates the number of bytes
* (1-7) of valid data contained within the remaining 7 bytes. For example, if
* the buffer had the following contents:
* 06 ff ff ff c0 01 04 aa
* This means that (06) there are 6 bytes of valid data. The byte 0xaa at the
* end is garbage (left over from a previous reception) and is discarded.
* If a read returns an "impossible" value as the length of valid data (such as
* 0x36) in the first byte, then the buffer is uninitialized (as is the case of
* first plug-in) and its contents should be discarded. There is currently no
* evidence that the top 5 bits of the 1st byte of the buffer can have values
* other than 0 once reception begins.
* Once valid bytes are collected, the assembled stream is a sequence of
* wrapped IrDA frames that is unwrapped and unescaped as in stir4200.c.
* BIG FAT WARNING: the dongle does *not* reset the RX buffer in any way after
* a successful read from the host, which means that in absence of further
* reception, repeated reads from the dongle will return the exact same
* contents repeatedly. Attempts to be smart and cache a previous read seem
* to result in corrupted packets, so this driver depends on the unwrap logic
* to sort out any repeated reads.
* Speed change: no commands observed so far to change speed, assumed fixed
* 9600bps (SIR).
