This is only the case with the Highway/Subway controller chips -- and only for keyboards/mice or other devices that need interrupt transfers. With the Algor and Deneb cards, there's no such drawback -- the more sophisticated controller chips take care of the protocol overhead with no host side interaction.

Thanks for posting, nice to see you still read this board. Good info on the various usb options.
What confuses me is that usb products is one product that is actually commercially viable. There is a worldwide demand for usb hardware for the classic platform. Someone mentioned Thyaciline, is that board being manufactured again?
The Deneb seems like some miracle board for classics as well and is no longer made. Will there ever be a comparable product for amigas? btw "Deneb" interesting and msytical name. Its starting to dawn on me there is a lot of symbology and ancient world iconagraphy in the amiga world. Your avatar has esotreric meaning as well. Or am I just up too late?
