Hi, I am trying to pass through an Adaptec 3805 card installed in the host to a Windows Server 2008 R2 VM. Windows Server sees the card, but when I tried to install drivers for it, I get a Code 10 error: This device cannot start. The card works on a regular (non-VM) Windows 2008 R2 box. My system is an Intel S5520HCT server board with 2 E5607 CPU's and 48 GB of RAM. There are no other addin/PCI cards installed.
