Abstract

A method and system for emulation of super speed external devices in a virtual machine (VM), including checking the ability of the VM Guest OS to support the super speed external device. If the super speed device is not supported by the Guest OS, device metadata is substituted by the metadata of the devices supported by the Guest OS. The method replaces the metadata of a new external device by the metadata of an older or different (supported) device. A VM acquires a descriptor of the external device configuration and 'patches' the device by replacing device version data from a new device version to an older (or different) device.
