  1. ... 49 0 0xffffff7f820e5000 0x1b000 0x1b000 net.osx86.kexts.GenericUSBXHCI (1.2.7) no UUID <40 12 7 5 4 3> ... USB 3.0 working. ASUS X99-A Mainboard, i7 5820K, GTX 980 Ti, Clover 3320, MacPro5,1 SMBIOS
  2. Update: with another disk, both front USB 3.0 ports are working. Maybe related to controller or cable.
  3. Update: external USB audio card is working. It takes about 15 seconds until it is activated. I checked all the ports, you're right. Not all ports are working. More details in the attached text file. AsusX99A-USB3.txt
  4. On Asus X99-A mainboard, GenericUSBXHCI v1.2.7 seems to be working again with the latest update to Mac OS X El Capitan version 10.11.2. External USB3 disk mounts perfectly fine with USB 3.0 transfer speeds.
  5. Update regarding ASMedia USB 3.0 on OS X 10.11.2: while external USB 3.0 disks are working natively, external USB sound cards aren't. Also, my system report is not listing a USB 3.0 bus at all, even while external disks are mounted. Any hints for a fix? IOReg attached. osx101102.ioreg.zip
  6. As with the latest OS X 10.11.2 El Capitan release, my ASMedia USB 3.0 ports (ASUS X99-A board) are working full speed. Life's good.
