midi2: boundary-aware drain in xfer_cb to keep UMP packets intact

midi2: drain pattern for RX FIFO

2026-05-17T22:56:04Z

Default RX/TX buffers to EPSIZE for both device and host. Document drain-in-loop on ump_read; example device callback drains until empty.

midi2: scale device buffers with EPSIZE

2026-05-17T16:07:21Z

Match midi2_host pattern. Literal 256 underran HS endpoints (512B).

midi2: per-interface weak callbacks for UMP Stream config

2026-05-17T15:19:45Z

Lets each instance return different NUM_GROUPS, NUM_FUNCTION_BLOCKS, EP_NAME and PRODUCT_ID. Defaults fall back to the macros.

midi2: peek 4 bytes for MT, restore 256 buffers

2026-05-17T14:31:12Z

MT is in byte 3 of the UMP word in LE memory, not byte 0. Buffers at mps blocked RX xfer re-arm on partial packets.

midi2: use hwfifo if supported

midi2: prevent UMP packet split across USB transfers

2026-05-16T15:59:44Z

The edpt_stream auto-flush is byte-oriented and could cut an UMP message in half when the FIFO reached wMaxPacketSize, corrupting the peer's RX context. Pre-flush whole packets before writing one that would cross the boundary on both device (tud_midi2_n_ump_write) and host (tuh_midi2_ump_write) paths. Host write also becomes packet-aware instead of word-by-word. Ref #3571
