ISO-Transfer is just a separate mode of data transfer like Bulk and Interupt transfers are.

Beside the other three protocols ISO transfer doesn't care about data loss. This means if data gets corupted or lost during transfer, no resend takes place to get acurate data. Its just gone. Thats why its used for video/audio transfer, where you simply get a frame drop, which nobody cares about.

The ISO transfer is controller specific, but all controlers use UHCI, OHCI and EHCI, so it would require to add the protocol to all three types of controllers to have full iso support for all devices on all systems.

AFAIR the daneb is using some embedded chip for usb, so it has nothing to do with the drivers MorphOS/Poseidon would need. AROS would be a source for proper drivers, too.

I have no clue about the current drivers, but I know I skipped the iso back at the times of AmithlonUSB as there were no stable application for testing the protocol.
