Message:

virtusb: add get_descriptor(config) handling

The virtusb framework is now able to handle the standard request for
obtaining configuration descriptor. This includes sending extra data
such as interface or endpoint descriptor.

Using this approach, the virtual keyboard sends also its HID descriptor.
