Failed to attach the USB device Lexar USB_3_0 Reader [0001] to the virtual machine deb-9.2.1.

Failed to create a proxy device for the USB device. (Error: VERR_PDM_NO_USB_PORTS).

Result Code: NS_ERROR_FAILURE (0x80004005)
Component: ConsoleWrap
Interface: IConsole {872da645-4a9b-1727-bee2-5585105b9eed}

Why?

This is an incompatibility between USB3 devices and USB controller (1.1 is default) on Virtualbox.

Solution

You need VirtualBox Extension Pack which has USB 2/3.0 Host controller. Unfortunately, this extension only supports each version individually. Make sure you download the correct extension pack. Virtualbox Downloads page

Then you have to set your USB controller to appropriate one. Done :slight_smile:
