Definition. A USB device that is plugged in identifies itself by its VID/PID combination. A VID is a 16-bit vendor number (Vendor ID). A PID is a 16-bit product number (Product ID). A host uses the VID/PID combination to find the drivers (if any) that are to be used for the USB device.
Add a USB Device to the Virtual Machine

Right-click on the Windows virtual machine and then select Settings options from the context menu. Click on the USB option present in the vertical menu. You will notice that the Enable USB Controller option is auto-checked. But it only offers support for USB 1.1 controller.

On an Android device, go to Settings. Go to About phone or About device and look for the device ID or IMEI number.
Vendor ID: The device manufacturer can be determined via the Vendor ID. Device ID: The Device ID identifies a device type within the range of a device manufacturer.
To identify the USB device in a Windows operating system:

Open the Windows hardware device manager to view all your computer hardware: Open the Run dialog box by pressing and holding the Windows key, then press R (“Run”). Type devmgmt. msc and press OK.

The BIOS setup program is displayed. On the left pane, select Settings > System Configuration > USB Configuration. The USB configuration is displayed on the right pane. Select or clear the Enable External USB Port check box to enable or disable it, respectively.
Activate USB support

Open up VirtualBox, right-click on the virtual machine that needs access to USB, and click Settings (Figure B). In the VM settings window, click USB. You should see that USB is now available. Click the + button under USB Device Filters to add a new device.

Go to Devices -> USB and select the printer. Share the printer and access it in the virtual session. After the USB connection has been established, VirtualBox printer sharing is enabled. The virtual machine will recognize the USB device and allow you to use it as if it were directly connected to your session.
Select the ESXi host on which your VM (to which you need to connect a USB device) is residing. Go to the Configure tab, then select PCI Devices in the Hardware section. Find and select the needed USB controller in the list of PCI devices by using the ID you have detected before.
Open the device properties and navigate to the details tab. Select “Hardware Ids” from the Property list. In the Value area, you will find the VID and PID of the product. On Linux, you can run lsusb.
Virtual USB (vUSB) is a mobile (app) debugging tool that simulates connecting a Sauce Labs real device directly to your local machine with a USB cable.
Standard USB uses a Master/Slave architecture; a host acts as the Host device for the entire bus, and a USB device acts as a Peripheral. If implementing standard USB, devices must assume one role or the other, with computers generally set up as hosts, while (for example) printers normally function as a Peripheral.
