I have two HP Proliant Servers (DL380 G5 and ML 350 G5) with very similar BIOS. Both are VM Hosts and everything is working well on them. I cannot, however, configure USB passthrough. The options in the vSphere client are greyed out. I have seen postings that refer to BIOS options that should be enabled to activate this option but nothing in the BIOS looks right. VT is enabled.

Any ideas?

Have you added a USB Controller to Both VMs.

and once you have added a USB Controller, you should be able to add USB devices to the VM.

You need to have a device connected to USB that is supported to make the USB device option able to be used.

I've also read, people stating to enable something in the BIOS!

But I think that's Urban Myth! (other than USB Enable / Disable!) - But that's only on noddy Desktop BIOS. Proliant BIOS I don't think have that rubbish.

Your server supports it or does not, and if it has USB ports, it's often supported  by the USB module loaded by ESXi on bootup.
