Description
With the current version of NoMachine installed (v5.2.11) it is not possible to pass thorugh USB devices to VirtualBox. The device lists in available devices, and when selected is removed from the Windows host. The VirtualBox status bar indicates that no device is captured and shows no read or write activity. If you hover over the status of the device, this says the device is captured, but 'lsusb' in a Linux guest does not show the device, only the hub. Attempting to capture the device results in an error 'E_INVALIDARG' and a message that the device is busy. Removing the USB device and reinserting leads to multiple copies of the device appearing in the list. To clear the list, VirtualBox has to be completely restarted. This appears to be a clash between the USB device handing in NoMachine and VirtualBox. I was trying to setup some VirtualBox VMs to test the current version of NoMachine.
Forgot to mention, removing NoMachine allows VirtualBox to access the USB devices as expected. I had previously removed USBPCAP and VMWare vSphere client as troubleshooting steps.
