lost usb after update from 6.0 to 6.0u2
Usb devices all disappeared after update patching from 6.0 to 6.0u2 on a Lenovo 10E9000SUS. Keyboard was no longer functional from the ESXi physical console and usb passthrough devices were no longer available. Rebooting + bios update had no effect. Resolved by full reinstall of ESXi from a 6.0u2 iso. The same update patch process on other same model systems went through without this problem. Still have more to go so would like to understand what might have gone wrong and how to avoid this.
Method used to update: esxcli software profile update -p ESXi-6.0.0-20160302001-standard -d https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml
This is the current good usb state on the server after the 6.0u2 reinstall:
