This builds on the PCI support to enable the discovery of USB devices. This is primarily intended to be used for the discovery of Edge-based heterogeneous accelerators that are connected via USB, such as the Coral USB Accelerator and the Intel NCS2 - our main motivation for adding this capability to NFD, and as part of our work in the SODALITE H2020 project. USB devices may define their base class at either the device or interface levels. In the case where no device class is set, the per-device interfaces are enumerated instead. USB devices may furthermore have multiple interfaces, which may or may not use the identical class across each interface. We therefore report device existence for each unique class definition to enable more fine-grained labelling and node selection. The default labelling format includes the class, vendor and device (product) IDs, as follows: feature.node.kubernetes.io/usb-fe_1a6e_089a.present=true As with PCI, a subset of device classes are whitelisted for matching. By default, there are only a subset of device classes under which accelerators tend to be mapped, which is used as the basis for the whitelist. These are: - Video - Miscellaneous - Application Specific - Vendor Specific For those interested in matching other classes, this may be extended by using the UsbId rule provided through the custom source. A full list of class codes is provided by the USB-IF at: https://www.usb.org/defined-class-codes For the moment, owing to a lack of a demonstrable use case, neither the subclass nor the protocol information are exposed. If this becomes necessary, support for these attributes can be trivially added. Signed-off-by: Paul Mundt <paul.mundt@adaptant.io>
