Hi,
any plans to support A4Tech mouse? It uses IMEX protocol, but

switch(packet[3] & 0x0F) {
    case 0: /* nothing */
    case 1: vertical_wheel--; break;
    case 2: horizontal_wheel++; break;
    case 0xE: horizontal_wheel--; break;
    case 0xF: vertical_wheel++; break;
}

and obviously it never reports wheel move > 1 in one sample.

Is there a way to detect whether it's an ImEx or A4? Or will we need a command line parameter ... ?
