Hello,
I had ESXi 5.0 and virtual machines created and running fine with USB devices assigned to virtual machines and then installed ESXi 5.5 replacing existing installation and I re-added to each virtual machine the USB controller (via VM right-click Edit Settings->Add button) but when trying to add devices back to the virtual machines it reports "There are no USB devices available on the host". I don't have enabled any "passthrough" in Configuration->Advanced Settings (that's what killed the previous installation of ESX).
Any idea how to add the USB devices again? Tried restarting the server several times. I have Dell PowerEdge R310 and it doesn't mentions anything about USB in BIOS.
Thank you in advance,
David.
