IONameMatch wrong for AMD matisse chipset USB controller

The name of the controller does not match the name of its container (not sure if that’s the correct term), so IONameMatch tries to insert ports (and also the power settings I included) at the wrong spot, and fails. A simple hack for my simple setup was to change the IONameMatch string to AppleUSBXHCIPCI from the name of the controller pci1022,149c. I’m sure you’ll know of a more elegant way to fix this in your script!

Thanks for the great work!!

I recently migrated USBMap to leverage IOPathMatch over IONameMatch - which should hopefully alleviate some issues with more exotic setups. The commit that added that functionality is here - but I’ve added some other fixes and etc since.

The issue with using a generic class match for IONameMatch is that it will apply to all controllers with that name - which, in your example is fine, as you are using the same ports for both of the ASMedia controllers - but for those with different types and ports, it won’t work. I suppose the search shall continue for a more reliable way - however, the IOPathMatch works fine for my ASMedia controllers (of which I have two, with different numbers of ports and different types), so I’m inclined to continue toward a solution that works with them individually over a blanket solution. If you make any other headway on the topic, please update me, but for now I won’t use the class as the IONameMatch.
