WMware ESXi 4.0 Passthrough not working
I have a WMware ESXi 4.0 running with 3 WM (windows servers). Yesterday I rebooted all 3 WM and since then passthrough is no longer working.
I have 2 USB drives for backups and it all was working fine before rebooting the the WMs. I did not reboot the ESXi host.
Now under Configuration > Advanced Settings I see "Host does not support passthrough configuration". And Configure Passthrough is grayed out
Any ideas why?

You should do below steps:
Add USB controller on VM.
Add USB device.
Connect USB device on VM.
I can't do the steps above. When in settings for VM i see "USB Controller (unavailable)"
My question is not how to add the USB drive. It does not work.
My questing is about why passthrough is no longer working. Please read my original questions again. Thanks for trying to help!
Have you tried to disconnect and reconnect USB devices on ESXi host?

You can check the bios for one of these settings. All must settings must enable:
Directed I/O / VT-d / Intel VT I/O / CPU Virtualistion
Is it posible to upgrade to version 5 ?
First i should check the bios settings of the server.
What kind of servers do you have ?

The server is a Dell Pwer Edge R515
Not ready to upgrade yet. Passthrough working up until yesterday I never touch the server. Just rebooted from the OS
I will shut down the VM's and server after hours today and see what happens

if you are using VM Direct Path I/O, have any BIOS changes been made, or firmware upgrades?
ASKER
Nope I have not upgraded the firmware or made any BIOS changes.
Is your server verified by VMware for VM Direct Path I/O ?
Are you using VM Direct Path I/O, e.g. added a PCI device to each VM, or are you using USB Passthrough?
the functions are very different?
e.g. see my EE Article
HOW TO: Add and Connect a USB Device to a Virtual Machine, hosted on VMware vSphere Hypervisor ESX 4.1 ESXi 4.1, ESXi 5.0

This solution is only available to members.
To access this solution, you must be a member of Experts Exchange.
What you are describing in the question is VM Direct Path I/O. I think you *ARE* using USB Passthrough, in what you describe in your last post.
USB Passthrough can be hit and miss.

If that is the case the host should support passthrough...correct?

At present your host does not support VM Direct Path IO.
which is the function of adding a PCI card in the host to a single VM.
Looking at the HCL, very few servers support VM Direct Path IO.
I did find a reference to release notes on Dell servers VMDirect Path
I/O behaves abnormally on AMD systems

Rebooting solved the problem. If anyone has objection to accepting my answer please let me know why and I will award points
Add USB controller on VM.
Add USB device.
Connect USB device on VM.
Have you checked USB Devices Supported for Passthrough from an ESX/ESXi Host to a Virtual Machine
