Three problems, but only two seems to have directly to do with the PCIe Cards, themselves.
- Card wake up with USB 3.0
- Drivers. Seem most, if not all cards, need their own drivers
- Interference with BT antenna (mouse/trackpad, typically, disappearing from screen or getting 'wonky' operation) when USB 3.0 devices used.
Does anybody have experience with which card(s) work best when there is no more BT issue? I am in the process of fixing the BT by replacing the internal antenna with an EXTERNAL BT ANTENNA to the internal MB card that it is hoped will solve the poor performance of the internal one.
Tried a Sonnet Allegro USB card and had major issues with the device attaching to it (Card Reader) media not on line after the drivers were installed, and the interference issue was no help. Clearly the Apple antenna design is a big hurdle to overcome.
