Post Intel 5 Series USB Controllers disappear after reboot
I have a very strange VMDirectPath problem with my VMware ESXi 5.1 server.

My motherboard used is MSI H55M-E33 which is able to support VT-d and i am able to configure passthrough for my ATI Radeon HD4550 but both my Intel 5 series/3400 series USB2 Controller keep on disappearing from the DirectPath I/O Configuration page instead after i reboot my ESXi 5.1 server.

I remember clearly that both my USB controllers was working fine in passthrough mode when i was using ESXi 5.0 previously as i was able to use my USB ports inside my VMs.

Please do see attached screenshots, i am really clueless on how to troubleshoot my problem further and i will be really grateful if someone here can guide me on how to troubleshoot my problem.

Can it be that the USB ports on my motherboard is spoilt ? If yes, i need to RMA my motherboard asap.
