2026-07-13rusb2: EP0 OUT reliability, HS UTMI PHY power-up, FS-only build supporthathach
- EP0 OUT: park a back-to-back data-stage packet the DCP accepted before PID could go NAK and deliver it into the next armed chunk; flow-control the single-buffer control pipe between chunks (usbtest ctrl_out corruption); discard a packet parked while an OUT pipe was halted so BOT reset recovery's fresh CBW read can't receive stale WRITE data - HS UTMI PHY power-up per the FSP sequence, shared by dcd/hcd: CLKSEL programmed from the board XTAL (EK-RA8M1 runs 20 MHz; the 24 MHz reset default never locks) while DIRPD holds the PHY down, then timed release - hw/bsp(ra8m1_ek): fix U60CK divider macro - BSP_CFG_U60CK_DIV used the generic USB_CLOCK_DIV_8 encoding (7), which USB60CKDIVCR rejects, leaving the USBHS link domain at 480 MHz; the USB60-specific BSP_CLOCKS_USB60_CLOCK_DIV_8 (4) sticks and yields the required 60 MHz from PLL1P - support FS-only builds on the high-speed port: gate SYSCFG.HSE on TUD_OPT_HIGH_SPEED (RHPORT_DEVICE_SPEED=OPT_MODE_FULL_SPEED was a silent no-op) and always compile both hwfifo access widths - the FIFO width belongs to the module, not the link speed (FS builds corrupted odd-length tails: 16-bit access against MBW-32) - iso activate: reset stale pipe bookkeeping so a BRDY firing before the class re-arms can't replay a pre-SET_INTERFACE transfer; write PIPEBUF after PIPESEL selects the pipe (PIPESEL-windowed register) - clear-halt: re-assert BUF on a still-armed OUT pipe (usbtest case 29) - bound the D0FIFO ready spin so an undrained double-buffered IN pipe can't freeze the stack with the IRQ masked - usbtest example: cap interrupt mps at 64 on RUSB2 high speed (pipes 6-9 have a fixed 64-byte buffer, RA6M5 UM 29.1) Verified: usbtest 30/30 on ra6m5_ek (HS), ra4m1_ek (FS) and ra8m1_ek (FS-forced build on the HS port).

2026-07-12dcd(ch32_usbfs): reset stale transfer state in dcd_edpt_iso_activatehathach
The no-op activate left a transfer armed before SET_INTERFACE valid in data.xfer, letting the ISR complete it against the old buffer. Drop the descriptor and NAK the endpoint (mirrors the nrf5x fix). Verified: usbtest 30/30 on ch32v103r, nanoch32v203, ch582m_evt. Co-Authored-By: Claude Fable 5 <[email protected]> Claude-Session: https://claude.ai/code/session_01HeF2gZ1M7GWkz6Av4BpKPg
2026-07-12dcd(ip3511): clear Active directly on stall/iso-activate, keep EPSKIP for reopenhathach
EPSKIP raises a transfer completion, so using it on the stall path let the class re-arm the endpoint and Active+Stall never actually stalled (usbtest case 13); write bare Active=0 instead, and retire skipped transfers on endpoint reopen where the completion is wanted. Verified: usbtest 30/30 on lpcxpresso11u37. Co-Authored-By: Claude Fable 5 <[email protected]> Claude-Session: https://claude.ai/code/session_01HeF2gZ1M7GWkz6Av4BpKPg

2026-07-03add ncm receive-path fuzz harness with out-of-bounds seedJavid Khan
folds the reproducer for the recv_validate_datagram bound into a small self-contained fuzz target. it feeds a raw ntb straight into the validator (the driver is pulled in so the static function is reachable) and ships the crafted 64-byte ntb as a seed. the seed trips an asan heap-buffer-overflow against the unpatched driver and is rejected cleanly with the wLength bound in place.

2026-07-01hcd(max3421): improve CHIPRES reset logic and refine oscillator ↵hathach
stabilization timing
2026-07-01max3421: prevent USB host hang at startupMikey Sklar
On some boards the MAX3421E doesn't report its oscillator ready after a soft reset (CHIPRES), so hcd_init() waits on USBIRQ_OSCOK forever and the host hangs at startup before any USB device can be used. Bound the wait so it proceeds after a timeout; it is a no-op where OSCOK arrives normally. Needed on the Adafruit Feather ESP32 V2 (classic ESP32) + USB Host FeatherWing, which otherwise hangs on essentially every cold boot. Relates to adafruit/circuitpython#10053.
