Using the latest version so 075 open core, none of my USB Ports, even when plugged into USB2-3 Ports. Any idea what it could be ?

Are u using the iMacPro1,1 SMBIOS?

[emmab2011]

Using the MacPro7,1, is that a problem ? I may have to change back to iMacPro1,1 then?

[SchmockLord]

Yes. because the USBconfig is SMBIOS-specific to iMacPro1,1

[SchmockLord]

You can use MacPro7,1. Just use this Kext.

@yeider1224 Same issue as discussed before: u are using a different SMBIOS (iMac20,1 instead of iMacPro1,1), the USBMap.kext is specific for iMacPro1,1. Open the info.plist in the kext and replace iMacPro1,1 by iMac20,1.
