Solution

1 If you have problems with autoconnection, perform these steps.

a Select the virtual machine and select Player > Removable Devices to disconnect and reconnect the

device.

b If the problem persists, unplug the device and plug it in again.

c If a warning message indicates that the device is in use, disable the device in the hotplug

configuration files in the /etc/hotplug directory.

The documentation for the Linux distribution contains information on editing these configuration

files.

2 If disconnection fails, either disable the driver or unload the driver manually.

Option Description

Disable the driver

If the driver was automatically loaded by hotplug, disable it in the hotplug

configuration files in the /etc/hotplug directory. See the documentation

for your Linux distribution for information on editing these configuration

files.

Unload the driver manually

Become root (su -) and use the rmmod command.

Using Smart Cards in Virtual Machines

Virtual machines can connect to smart card readers that interface to serial ports, parallel ports, USB ports,

PCMCIA slots, and PCI slots. A virtual machine considers a smart card reader to be a type of USB device.

A smart card is a plastic card that has an embedded computer chip. Many government agencies and large

enterprises use smart cards to send secure communication, digitally sign documents, and authenticate users

who access their computer networks. Users plug a smart card reader into their computer and insert their

smart card in the reader. They are then prompted for their PIN to log in.

You can select a smart card reader from the Removable Devices menu in a virtual machine. A smart card

can be shared between virtual machines, or between the host system and one or more virtual machines.

Sharing is enabled by default.

When you plug a smart card reader into the host system, the reader appears as two separate USB devices in

Player. This is because you can use smart cards in one of two mutually exclusive modes.

Shared mode

(Recommended) The smart card reader device is available as Shared

smart_card_reader_model in the Removable Devices menu. In Windows XP

guest operating systems, the shared reader appears as USB Smart Card

Reader after it is connected to the virtual machine. In Windows Vista and

Windows 7 guest operating systems, the generic smart card reader device

name appears under the Windows Device Manager list. The smart card

reader can be shared among applications on the host system and among

applications in different guest operating systems.

USB passthrough mode

The smart card reader device is available as smart_card_reader_model in the

Removable Devices menu. In USB passthrough mode, a single virtual

machine directly controls the physical smart card reader. A USB passthrough

smart card reader cannot be used by applications on the host system or by

applications in other virtual machines. You should use USB passthrough

mode only if connection in shared mode does not work well for your

scenario. You might need to install the driver provided by the manufacturer

to use USB passthrough mode.
