Of course not. Not if they're USB.
Eh, not so fast. The driver for my Intel "Create and Share" cam, "gspca",
reserves USB bandwidth. If you have two of them hanging off a hub, the
first one gets the bandwidth, and the second one chokes. At least
that's how I think it works; I only have one.
Possible, but that would Really Bad Design[tm].
Have you tested that, say by monitoring the transfer speed to/from an USB
disk?
They're not supposed to reserve bandwidth on a shared resource. Not until
they need it. And even then only the strict minimum. Which is nothing, in
this case: a single snapshot from time to time.
But thanks for the info, I'll watch out for that, in my upcomming purchase.
(note to self: stay away from Intel cams)
