Whatever scheme the USB approach uses, it should accomodate the pervasive

have a hub inside the box anyway).
Do USB devices have internal serial numbers?

This is a technology I don't fully understand, but I can report that for
the SDR, hubs (at least the external kind) simply don't work.
Whether we "should" or not is a matter I leave to those better attuned.
That they don't work is a matter of (in my case) actual experience.
Many have told me that hubs are the spawn of Satan and, on my
experience with them to date, I have to agree.
That's how I ended up buying the PCMCIA card to provide extra "full up"
USB ports which has its own problems, but which I was ultimately able to
make work as long as the SDR wasn't plugged into it. I would regard
that as a more serious problem than not supporting hubs.
As long as we're still using what is, at core, the parallel port
interface, I presume that we will have more restrictions than usual.
