cheap-o via usb card works fine on mine: https://www.ebay.co.uk/itm/USB-2-0-4-Port-Card-Adapter-480Mbps-High-Speed-VIA-HUB-PCI-Controller-Adapter-UK/283018790752?epid=1687887909&hash=item41e53c0760:g:NokAAOSwVwRa~Wse:rk:20:pf:0

My m-audio 410 FW works also fine on built-in FW ports under MacOS X and Debian, but not MorphOS (obviously), ditto for my external WD 1tb hdd, much much faster than any usb disk.
