2026-07-07	Enable 4-packet bursts on CH569 SuperSpeed bulk endpoints	hathach
	- 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).

2026-07-07	Add SuperSpeed support to cdc_msc_throughput example	hathach
	- SS device/config/BOS descriptors with endpoint companions, speed-aware EP0/CDC/MSC buffer sizes (same pattern as cdc_msc) - Lengthen the CH569 SuperSpeed-training fallback timeout to 1 s per phase: training from a host port settled in another connection state can exceed the previous 0.5 s window Measured on HydraUSB3 v1 at 5 Gbps (NUMP=1): MSC sequential read 70-79 MB/s, write 55 MB/s via dd direct IO - about 3.5x the USB2 high-speed fallback figures on the same setup. Burst support (CFG_TUD_WCH_USB30_MAX_BURST > 1) remains the main headroom. Co-Authored-By: Claude Fable 5 <[email protected]>

2026-04-26	shrink cdc_msc_throughput MSC buffer for FS targets	hathach
	CFG_TUD_MSC_EP_BUFSIZE: 4096 → (HS ? 4096 : 1024). Keep the big buffer for HS where it actually amortises CBW overhead at iperf-class throughput; FS peaks around ~830 kBps so 1 KB is plenty and the example now fits on small-RAM MCUs (lpc11/13, samd11, kinetis_kl, stm32f0/l0, stm32f1, etc.). Also dedupe CDC_TX_BUFSIZE = CDC_RX_BUFSIZE. Drops the previously-needed skip.txt — verified builds locally on lpcxpresso1347, cynthion_d11, lpcxpresso11u37/u68, stm32f072disco/eval, frdm_kl25z, stm32l052dap52.
