I am running an Ubuntu 20.04 guest on an ESXi 6.7.0 host. I want to pass a USB device (M5 Atom Lite) through to it. I already have two USB hard drives passed through to the same guest O/S without any issues.
Whenever I try to add it as a "USB Device" I get a message saying "There are no more usb devices available to add".
I have tried both the front and rear USB ports on the hardware (HP Microserver Gen 8), but get the same error in both cases.
Any idea why I can't add this device, when I have already successfully added two other USB devices?
