Looks like VMware change the USB driver method and only put vmkusb driver instead of XHCI/EHCI/UHCI/OHCI.

Vmware KB: Important information about the new ESXi 6.5 USB driver vmkusb, and the legacy USB drivers (2147650)

virtuallyghetto: No suitable disk was found when upgrading to ESXi 6.5 on USB?

Upgrade ESXi 6.0 to 6.5 from command line, if web traffic is OK with the host.

Something went amiss here: For one of the hosts (an old Dell PowerEdge) the update did not succeed. After reboot the host was back on 6.0.0. Looks like 6.5 was installed on a disk drive (and not the USB stick). After reboot, logs shows not evidence of the update (for the 6.0.0 installation on the USB stick).

If anybody is using the online update (as described below) to update an 6.0.0 on a (USB) stick - please let me know.

Step 1: Enable maintenenance mode and allow web traffic.

esxcli system maintenanceMode set --enable true
esxcli network firewall ruleset set -e true -r httpClient

(and close AFTER you are done)

esxcli network firewall ruleset set -e false -r httpClient
esxcli system maintenanceMode set --enable false

Step 2: Get available packets (for 6.5)

esxcli software sources profile list -d https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml | grep -i ESXi-6.5

Should get you something like this:

For build 4564106-standard image:

esxcli software profile update -p ESXi-6.5.0-4564106-standard -d https://hostupdate.vmware.com/software/VUM/PRODUCTION/main/vmw-depot-index.xml

For some reason, first update failed.

Been testing a bit: After the update completed. i.e.:

Update Result
Message: The update completed successfully, but the system needs to be rebooted for the changes to be effective.
