Just upgraded PC and motherboard to:
i7 3770k CPU 3.30Ghz
16bg OG RAM
WINDOWS 7 64 bit
ASUS P8Z77-V LX2 MOTHERBOARD
SSD OS DRIVE
(also tried with an upgrade to latest MB BIOS)
I have the powercore element and have install 4.4.1b47 powercore software and also tries 4.3.3 with the same results. Windows device manager sees the powercore card and says its working ok but the Powercore status windows says unknown device even though it can read its firmware version number and show what plugins are enabled in the plugin window. I am running Cubase 7 and all plugings are showing as disabled in cubase.
Here is a youtube video showing the above problems http://youtu.be/dj82R7g4dHo
