Mediating communication of a universal serial bus device

摘要

In an example, an apparatus includes a memory storing a hypervisor, where the hypervisor is configured to determine whether one or more universal serial bus (USB) devices in communication with the hypervisor are authorized to communicate with a guest operating system of the hypervisor and, after determining that the one or more USB devices are authorized to communicate with the guest, virtualize the one or more USB devices at the guest operating system and transfer messages between the one or more USB devices and the virtualized USB device.

1. A computing device comprising:
at least one processor; a hypervisor operable by the at least one processor as a primary operating system and configured to:
determine whether a universal serial bus (USB) device is authorized to communicate with a guest operating system managed by the hypervisor;only after determining that the USB device is authorized to communicate with the guest operating system, virtualize the USB device to present a virtual USB device to the guest operating system and transmit messages between the USB device and the guest operating system through the virtual USB device; andvirtualize one or more devices in addition to the USB device at the guest operating system.
