- Default CFG_TUD_WCH_USB30_MAX_BURST to 4 (tusb_mcu.h): matches the
link layer's header-packet buffer count (NUM_HP_BUF). Burst 8 fails
to configure; the TeenyUSB-reported burst corruption quirk did not
reproduce with per-burst DMA re-arm (50x MSC write/read-back and
256KB CDC echo integrity all clean at burst 4)
- Bounce slots stay one max packet regardless of burst (bounced
transfers cap their burst to the slot; zero-copy uses the full burst)
so the RAMX pool no longer scales with burst size
- cdc_msc/cdc_msc_throughput SS descriptors advertise
bMaxBurst = CFG_TUD_WCH_USB30_MAX_BURST-1 via the
CFG_EXAMPLE_SS_BULK_MAXBURST knob (0 for non-WCH SuperSpeed ports)
Measured on HydraUSB3 v1 at 5 Gbps (HIL cdc_msc_throughput): MSC read
147 MBps write 127 MBps - about 2x the single-packet figures (raw dd:
up to 163 MB/s read at 1M blocks).

Groundwork for TinyUSB's first SuperSpeed port (WCH CH569):
- TUSB_SPEED_SUPER, OPT_MODE_SUPER_SPEED, TUD_OPT_SUPER_SPEED and
TUP_RHPORT_SUPERSPEED capability plumbing
- Allow CFG_TUD_ENDPOINT0_SIZE 512 on SS builds; EP0 control transfers
chunk at the runtime link speed (512 at SS, 64 on USB2 fallback)
- Handle SET_SEL, SET_ISOCH_DELAY and U1/U2_ENABLE feature requests
- Tolerate SS endpoint companion descriptors in usbd_open_edpt_pair,
cdcd_open and mscd_open interface parsing
- SS descriptor types/structs and template macros: endpoint companion,
BOS USB2-extension + SuperSpeed capability, SS config and
CDC/MSC/vendor SS variants (bulk fixed at 1024)
- cdc_msc example: SS device/config/BOS descriptors, speed-aware sizes
- Unit tests: SS endpoint validation, companion-tolerant endpoint pair
open, SET_SEL, SET_ISOCH_DELAY
All SS paths compile out when disabled: verified 0-byte code-size delta
on stm32f407disco (MinSizeRel) vs master; 65/65 unit tests pass.

Documentation tooling:
- Add the `build-doc` skill and `tools/build_doc.py` wrapper for local
Sphinx builds (clean / -W / open).
- Enable Markdown (MyST) in conf.py and auto-collect
examples/{device,host,dual}/*/README.md into a 3-level Examples nav
(Examples > Device/Host/Dual > example), noting each page's source
location and normalizing headings to a single H1.
- Remove the stale `.claude/commands/build-doc.md`; point the AGENTS.md
Documentation section at the skill.
Example docs:
- Add a README.md for every device/host/dual example: what it does, USB
interface table, notable tusb_config.h settings, generic CMake + Make
build steps, and how to try it.
- Fold each *_freertos variant into its base README, noting the FreeRTOS
source path and any RTOS-specific behavior.
Generated docs/examples/ output is git-ignored. Builds clean with
`sphinx-build -W`.
