Well back then when Elbox was planning USB support, Chris Hodges probably thought (as everyone else, except Elbox) that it would work "normally", you know... Mediator owner walks into any computer shop, buys an USB card that has compatible chipset, plugs it into his Mediator, confirms that it works and THEN registers Poseidon.
Exactly. I purchaced my mediator on the premise that I could use it with bog standard PCI cards as long as there was a driver.
At the time I purchaced it there were voodoo3,sb128,realtek and bt848/878 drivers. And mpeg2 card + usb card drivers were "coming soon".
However Elbox decided they would lock their USB drivers down to only the USB card they were selling at an inflated price.
I would have paid elbox extra for a usb driver I could use with a well known USB card and a well known Amiga stack.
But pay for an over priced card, with a driver that would be useless on any other card with a different id, filled with malicious code and an illegal development licence for someone elses software. Elbox you be wrong.
