HI AberDino, we are running an HP ML350 Gen 8 and with ESXI 5.1 update 1 and can't get USB option to stay enabled after reboot.
How are you getting it to work, because when we tick the USB Bus's we want to enable I thought we had to reboot before it would work. Once server is back up after reboot they show as unticked.
Are they actually working even though they don't show ticked?
We would like to find a work around until Vmware catch a wake up and fix this important feature!
please let us know how you making it work?
