摘要：
A method, apparatus, system, and computer readable medium are disclosed. In one embodiment the method includes detecting a virtual machine (VM) attempting to communicate with a device coupled to a computer system using a first software plug-in interface that is incompatible with the device. The method continues by temporarily removing the VM from controlling system. Then the first software plug-in interface in the VM is replaced with a second software plug-in interface, which is compatible with the device, without the knowledge of the VM. Then control is returned to the VM and the VM is allowed to resume the communication attempt with the device using the second software plug-in interface.
