I'll bet there is some documentation on this somewhere, but I can't find it. This isn't really a Linux-USB question, more just a USB question, but all the same I'd really appreciate a pointer to information on the following question:
First, some background. I've got a class implementing a USB to DMX-512 convertor for theatrical applications. DMX-512 is a standard for controlling light dimmers; the basic idea is that it keeps sending intensity levels to 512 dimmers over a serial line, over and over. The gadget we're building uses a little microprocessor to store the intensity levels; the host updates the levels as needed and the microprocessor keeps shipping the levels out. The question comes when it's time for this device to identify itself to the host. The manufacturer might best be described as "homebrew" and the device class as "oddball." Are there manufacturer IDs that are reserved so that I can be confident that if I pick it, I won't be landing on something that will later be assigned to a real manufacturer? Similarly, are there class IDs that I can be confident won't be assigned to a real class someday? Or do I just have to grab one and hope for the best? I guess I'm hoping for something analogous to the 192.168.x.x IP addresses... -- Joseph J.
