Sorry I'm probably just being Thick here but if this is the case then I have to ask; How does the Anaiis USB stack work then??? :-?
Because it claims to be working on a pretty much stock Amiga 2000 with ZorroII Highway USB and 68000 processor (7.14 Mhz).
Anaiis is only the USB stack itself, (Think Windows Driver).
You still need the USB HARDWARE itself, for the stack/Driver to control.
Now, In THEORY, you could have a ZorroII bus USB card, but we are back to the CPU USAGE of USB. One way around, is to have the CARD ITSELF handle all the MIPS required to handle the transfer's. But to do this, you still need DMA, Otherwise, the CPU cops all the work. Back to square 1.
Modern PC's have several advantages, CPU Speed (Raw grunt), as well as DMA Channels, which means CPU doesn't get bogged down.
