INATECK KT4004 + MAC PRO 3.1 EARLY 2008 + OS 10.10.2 YOSEMITE

According INATECK not officially support OS 10.10.2 Yosemite. On your own risk you can of course install the card and try anyway under YOSEMITE. As far as the card does not work right away, here are some possible solutions: If available, the three files

SYSTEMDRIVE 'Library' Extensions> CalDigitHDProDrv.kext
SYSTEMDRIVE 'system' Library 'Extensions> CalDigitFastIO.kext
SYSTEMDRIVE 'system' Library 'Extensions> CalDigitUSBxHCI.kext

Delete (unless you have a backup in place, first make a copy). Restart. After I had when connecting and operating a USB3 disk interference in the Bluetooth connectivity of the Magic Mouse. Solutions:

1) reset parameter RAM. The four USB ports to try each case individually.
2.) Remove and Neukonnektieren all Bluetooth devices. Reset parameter RAM.
Reset 3.) Repositioning the PCI card from No. 2 to No. 3 or 4. Parameter RAM.

Result: interference eliminated. I reach the MAC PRO 3.1 on the INATECK KT4004 data throughputs from external to internal, three times as high and fast to two, as in a USB2 connection. Not outstanding - for me but more than satisfactory, especially when you consider the price of the ticket. The ratio price / quality / sustainability contribution is absolutely top !!!
