Resubmission after the counter wraps can therefore alias the elapsed time and skip the next established service phase. Cap the host-selected interval to one HFNUM cycle using the root-port frame unit. USB permits a shorter host-provided period, and the bounded interval keeps phase calculation unambiguous for native and split endpoints. 2026-09-02T14:14:26Z HiFiPHile admin@hifiphile.com 2026-09-02T01:54:17Z urn:sha1:14060950b487f931d959699c42b0875c96ca6a01 Periodic DMA channels use their natural service-boundary halt instead of a software CHDIS request. Keep the endpoint busy after an abort so a replacement transfer cannot reuse its state or buffer while the channel remains active. When HCINT.HALTED arrives, release the channel without reporting completion for the aborted transfer. If endpoint closure is also pending, release the endpoint from the same halt path. 2026-09-02T13:21:41Z HiFiPHile admin@hifiphile.com 2026-09-01T15:44:58Z urn:sha1:51761d2dfdf2036395b0b6ada6fdde213f97416f 2026-09-02T13:21:41Z HiFiPHile admin@hifiphile.com 2026-09-01T15:24:13Z urn:sha1:a52b5a0c25d2cfea286d67eb3d9d8891a9b69e8f A disconnect can close endpoint zero after an enumeration control stage completes but before USBH submits the next stage or request. HCD submission then legitimately returns false; treating that result as an invariant violation asserts during rapid replug and can leave enumeration unfinished. Complete an in-progress control request as failed when its DATA or status stage cannot be submitted. Propagate submission failures from every asynchronous enumeration continuation and finish enumeration through the normal failure cleanup path. This keeps controller teardown races out of assertions without fabricating a successful transfer. Validated by interrupting enumeration during rapid STM32U5A5 replug tests with DWC2 DMA and slave modes. 2026-09-02T13:21:41Z HiFiPHile admin@hifiphile.com 2026-09-01T05:06:47Z urn:sha1:3a1dc0dc1f57d45ed75aa9e176425901270e982e A root-port disconnect invalidates every active transfer. Retire channel and FIFO interrupt sources plus host-channel state in the disconnect ISR using the Linux DWC2 cleanup model instead of reinitializing the core and PHY, which can sleep on STM32 HS PHYs. Flush posted slave requests, request halts for enabled channels, clear channel interrupt and software ownership, and keep endpoint records closing until USBH processes the remove event. Reject transfer submissions to closing endpoints, preserve fast-replug notification, and re-enable the global host-channel interrupt when a new channel is initialized.
