Hello all,   I'm installing a Cisco UCS with integration with VM-FEX and Hyper-V 2012. The question is, after the virtual machine windows 2008 R2 x64 installed some drivers wasn't installed. All drivers in the windows host is installed. I tryed many times install the driver of "unknown device" but was unsuccessful. Anyone have passed for this before? what I have do to for solve this? What device is this?   Thanks.
