True, when you only need to support one - your - device. But things fall apart quickly when you suddenly have to support 37 modifications, versions and clones of the device that you once rev-engineered. > An intentionally obscured protocol, or a transport that is hard to > reverse-engineer would be, though.

Since your device appears to use relatively low traffic (compared to audio and video devices), it should not be a big problem. > > talks about IrDA device, not USB - is this the device, or what?

Well, I haven't heard of anyone using (or having, to that matter) this quite a specialty device. Nobody on this list seemed to recognize it either. Then, if you have it, you should plug it into a Linux box and look at descriptors. If it is a class-compliant device (of some class, don't know which one) then the driver already exists. If it is a vendor device then break out your USB sniffer ;-) Dmitri
