Aggressive?? Not sure why you said this. I’m just sharing my experience, and sharing Apple’s own advice when USB1 cards were released. Nothing more. |

Thank you all for your help. I just wanted to know if I could use the cards I have in that machine. Now I’ll just try to find another home for them and free the space for something else! |

I've just got one working in MacOS8.6 in my 4400/160 after a lot of jiggery pokery, forehead slapping and some colourful metaphors.
Hope the device ID's help. Speed wise it's charging at EHCI and correctly configuring USB2 stuff but it's staying in 12Mbps mode. I plan to have another hack around in resedit later tonight or tomorrow when I get a moment. |

Speed wise it's charging at EHCI and correctly configuring USB2 stuff but it's staying in 12Mbps mode. Unless you did something extra special, Classic Mac OS doesn't support anything other than USB 1.1.
It will support USB 2.0 peripherals (as you've seen), but it will always run them at USB 1.1 speeds, even on hardware that otherwise supports higher 2.0 speeds.

It'd seem you're correct. I can get USB2 signalling, but can't for the life of me get it rocking past 12Mbps. Works beautifully but is slow. 🙁 Jiggered around significantly with several cards. |
