I have a pretty simple question. If a physical device advertises a function with class 255, subclass 1, protocol 0, and another with class 255 subclass 2, protocol 0, is it possible to access both of these functions at the same time? 

[snip entire reply]

I forgot to add, what I said about the interfaces should not actually be affected by what the class, subclass and protocol of the interfaces are, with the possible exception of the interfaces being vendor specific. If the device is to spec it should behave as I said. If its vendor specific it may be allowed some leeway for eccentricities because its the vendors problem to work with them.
