+/*
+ * 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).
