I tried my highpoint and caldigit usb 3.0 cards and both no longer work. They did in the DP's.

My CalDigit PCIe card in my current gen 12-Core Mac Pro is working perfectly. Have a third SSD docked via USB 3, using it as a cache drive for Photoshop and other apps.

They released new drivers/kext's about 1-2 weeks ago. What's happening with your card? Maybe I could help.
