Hi all!
So I bought ga-z77x-d3h mobo and Intel CPU (without "K") and VT-D if fully supported on ESXi 5.1 which is great.
I installed ESX onto USB 2.0 stick plugged into USB3.0 port. Also doing great 
Now my problem is that if I install ESX onto USB 3.0 stick it installs just fine and also boots but it stops at "Running usbarbitrator script".
This happens only if USB 3.0 stick is plugged into USB 3.0 port on MB.
If I put this same stick in USB 2.0 port server boots up just fine.
Any ideas how to boot and run ESX from USB 3.0 stick on usb 3.0 port?
It boots waaaay faster than on USB 2.0 port but this honestly is the only difference I noticed...
Regards,
Greg
P.S.
If someone interested, Marvell controller on this MB has native support since 5.1 but Atheros NIC has to be enabled with VIB install and then it also works
