Connecting USB Devices to a Virtual Machine
Parallels Desktop allows you to connect up to eight USB 2.0 and five USB 1.1 devices to a single virtual machine. This means that you can plug up to eight USB 2.0 devices and five USB 1.1 devices into your Mac and connect them to your virtual machine. To use this feature, you must add a USB controller to the virtual machine configuration. If the USB controller is already present, make sure it is connected.
By default, when you plug a USB device into your Mac with one or more virtual machines running, the New USB device detected dialog appears:
In this dialog, you need to specify where the detected USB device will be connected:
If you want Parallels Desktop to remember your choice, press the Alt button on the keyboard and keep holding it when choosing where to connect a USB device. The next time you plug this USB device into your Mac, it will be automatically connected to the destination you specified in this dialog. To change the destination, use USB Preferences in the Preferences dialog.
To be able to use the USB device in the virtual machine, you may need to install the necessary drivers in the guest OS. By default, such drivers can be obtained from the manufacturers of this device.
Note: If you plug a USB 1.1 device into the USB 2.0 port, the port will be identified as USB 1.1.
To disconnect a USB device from your virtual machine, do one of the following:
Connecting iSight camera to a Windows virtual machine
If you have a built-in iSight camera, you can use it in your Windows XP or later virtual machine. Before connecting the camera, you should install the iSight driver for Windows in your virtual machine. There are several ways to install the driver. For example, you can install the iSight driver together with the Boot Camp drivers in your virtual machine:
Note: The iSight driver for Windows is suitable for built-in cameras only. External cameras are not supported.
To connect the iSight camera, click the USB controller icon in the virtual machine status bar and select the iSight camera in the list.
Connecting a USB printer to a virtual machine
You can connect a USB printer directly to your virtual machine. In this case, the printer will not be available to Mac OS X.
Note: If you want the USB printer to be available both to your Mac and the virtual machine, you should connect the printer to the virtual machine using a printer port. For detailed information, see Sharing a Mac Printer.
To connect a USB printer directly to a virtual machine:
Then do one of the following:
In the Windows guest operating system, follow the Add New Hardware wizard instructions. In the Linux guest operating system, follow the procedure for adding a USB printer specific for this Linux distribution.
Connecting Common Access Card reader
The Common Access Card (CAC) reader can work simultaneously in Mac OS X and in one virtual machine.
