Patent ID: 11604741

Abstract:
Methods and apparatus for dynamically provisioning virtualized functions in a Universal Serial Bus (USB) device by means of a virtual USB hub. The virtual USB hub includes a USB upstream port configured to be connected to a host system and at least one external bus or external interface to which devices including non-USB devices or computing devices in which non-USB devices are embedded may be connected. The virtual USB hub is configured to detect the non-USB devices and/or functions performed by the non-USB devices and generate corresponding virtual USB configuration information under which virtual USB devices and/or functions are connected to downstream virtual ports in the virtual USB hub. The virtual USB configuration is presented to the host computer to enable the host computer to communicate with the non-USB devices and/or their functions. Also disclosed is an I3C probe having an embedded virtual USB hub and configured to communicate with I3C devices and/or functions embedded within a target system under debug. USB devices may also be virtualized in a similar manner.
