And I forgot to say that what I described is the "isochronous" mode. This mode is designed for audio use. There is a minimum fixed bandwidth reserved for signal transmission, so that you don't get problems with dropouts because the bus was too busy. There is also a disadvantage in that there is no mechanism to check that the packet arrived without corruption and therefore also no mechanism to re-send bad packets. But these are not problems in the real world.
Asynchronous and adaptive modes are both sub-categories under the isochronous mode. So is synchronous, but that is generally only used for A/D converters when the data is being sent to the computer.
