USB Support in Zephyr OS

links:none on file
slides:none on file

Overview of Zephyr's overhauled USB stack: a new UDC driver API and thinner common layer replace the old monolithic code, device-side now supports multiple configurations (was single), per-endpoint request queues using net buffers, and runtime-updatable strings and descriptors. Host-side work includes a host controller API with a max3421e SPI driver and a virtual bus/virtual controller that runs host and device in one Zephyr image to enable fast automated testing and USBIP export; samples and shell commands demonstrate control and bulk transfers and they work end-to-end.
