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.
