- A USB device (Feitian HID dongle) is physically attached to a VMWare ESXi host (5.1.0).
- The USB dongle is configured in passthrough mode for a Windows 2012 R2 (VMWare Level 8) host.
- The Windows host does not "see" it - it doesn't appear in device manager or in the removable devices list.
Same device on same host if configured for a Linux guest comes up in the lsbusb output.
