This doesn't have to be true, at least for most cameras, and depends on the
driver. When I worked for Steve Sisak (Codewell, now IOXperts) writing USB
camera drivers on MacOS, we would usually provide a way to set the
bandwidth, and, in any case, would try to get by on what was available by
using different alternate settings. I don't know about drivers for Linux.
Yes. You are right. Now I remember the problem was when using that
common Genius webcams. Someone told me to install 3 usb additional cards
if I want 4 cams (one driver comes integrated with the motherboard).
Luck!
