Does anyone have experience with the `Host USB Device` option(USB pass through lite)in esxi that is found in vm settings in virtual hardware? I have noticed weird behavior where only 1 of the two usb drives in the back will be available for passthrough. Tested on two hosts and both have similar behavior but vary on which port will be chosen.

esxcli storage core device list | grep -i usb

Its weird because esxi seems to see them when i disable usbarbitrator. In this case the A-DATA device and Avocent Mass Storage Function? are displayed but no SanDisk Cruzer in virtual hardware.
