raw_gadget: fix MSC recovery after endpoint halt

2026-07-29T13:56:12Z

Allow opt-in DCDs to queue transfers behind a halted endpoint without changing hardware DCD behavior. Retry dummy_hcd's transient EP_SET_HALT failure, queue MSC BOT status and recovery requests behind the halt, and clean up Raw Gadget endpoint workers across bus reset. Signed-off-by: Zixun LI

raw_gadget: address transfer allocation review comments

2026-07-24T09:11:14Z

Initialize and clean up the Raw Gadget review findings. Use a single variable-sized allocation for each asynchronous transfer job, including the usb_raw_ep_io buffer, instead of allocating the job and ioctl buffer separately. This reduces allocation overhead and simplifies all cleanup paths while retaining support for variable-sized transfers without introducing fixed buffer limits or transfer pools.

Good catch. `configured` must be initialized explicitly because the context storage is not guaranteed to be zero-initialized at this point. I will set it to `false` in `raw_gadget_context_table_create()` and review the remaining context fields for the same issue.

raw_gadget: include tusb_option.h explicitly

2026-07-24T09:11:14Z

Include tusb_option.h directly from raw_gadget_private.h instead of relying on transitive includes. This makes the header self-contained and removes the implicit dependency on include order, ensuring that TinyUSB configuration macros are always available where they are required.

dcd/raw_gadget: add Linux Raw Gadget backend

2026-07-24T09:09:54Z

Add a TinyUSB device controller driver for the Linux Raw Gadget interface. The driver implements the TinyUSB DCD API on top of the Linux Raw Gadget userspace interface and supports: - Control transfers (EP0) - Bulk endpoints - Interrupt endpoints - Dynamic endpoint configuration - Remote wakeup handling - Stall and clear-stall - Asynchronous transfer processing Isochronous transfers are not supported because the Linux Raw Gadget API does not expose the required functionality. The implementation is intended for development, testing and virtual USB devices running entirely in userspace on Linux.
