If support for isochronous transfers is added, it should be done correctly. That is, the implementation should support scheduling of transfers, periodic bandwidth reservation, high-bandwidth transfers, and so on. The whole point of dummy-hcd is to emulate a real host controller as closely as possible. Real isochronous transfers do not complete all at once. Alan Stern
