* license: use SPDX identifiers for src/ headers Replace the full ~20-line MIT license boilerplate on every src/ file with a two-line SPDX tag (SPDX-FileCopyrightText + SPDX-License-Identifier), following the REUSE convention used by CircuitPython and the Linux kernel. Removes ~3500 lines of duplicated boilerplate.

rp2040: fix host SET_REPORT (and any OUT-data control xfer) sending DATA0 instead of DATA1

2026-05-15T19:28:21Z

hcd_edpt_xfer() previously reset ep->next_pid to 1 only when the control endpoint direction changed between stages. That handled IN-data control transfers (e.g. GET_REPORT, GET_DESCRIPTOR) where SETUP is OUT and DATA is IN, but not OUT-data class requests like SET_REPORT, where SETUP and DATA are both OUT and the direction-change check is false. ep->next_pid was left at 0 from hcd_edpt_open(), so the DATA stage went on the wire as DATA0 when the device expected DATA1. Strict devices (observed: Elgato Stream Deck) treat this as a protocol violation and disconnect. Key off "endpoint 0" instead of "direction changed", restoring the previous behavior. Interrupt/bulk endpoints take the ep->interrupt_num > 0 branch above and never reach this code, so they are unaffected.

Apply suggestion from @Copilot

rp2040: fix RP2350 hard fault in unaligned_memcpy to USB DPRAM

2026-04-02T16:50:12Z

Use volatile byte accesses to prevent the compiler from widening the byte-by-byte copy loop into 16/32-bit accesses, which cause a hard fault on RP2350 when targeting USB DPRAM (device memory). Closes #3554

fix issue caused by merging active + pending state

reduce code size, use state to replace active + pending

finally get rp2040 host epx working with 2-sof solution for switching

2026-03-31T16:53:56Z

host abort transfer on short packet in double buffer.

2026-03-31T09:01:58Z

hcd rp2 add double buffered for control endpoint transfers.
