ohci: enumerate a device that was already attached at init

2026-09-05T08:25:14Z

hcd_init() clears every pending interrupt flag before enabling its own set: OHCI_REG->interrupt_status = OHCI_REG->interrupt_status; If a device is already connected at that point, that write drops the RHSC which went with the connect, while the root hub keeps ConnectStatusChange set. The device stays put, so no new edge follows and the attach is never reported - the port sits at CCS=1, CSC=1, PES=0 forever. Host-only builds got away with it because the connect is usually detected after that clear. In a dual build the device stack initialises first and enables the shared USB interrupt, which moves the detection into the window that gets cleared, and the host then never sees the device. Scan the root-hub ports once at the end of hcd_init and raise the attach ourselves, clearing the stale change bit so the next RHSC does not report the same device again. Verified on ea4088_quickstart: dual/host_info_to_device_cdc now enumerates on a plain reset (HIL test passes, "Device 1: ID 1a86:8010 SN 7FD88F0604B5"), host/device_info still enumerates, and device/cdc_msc is unaffected. host/device_info also builds for lpcxpresso55s69, lpcxpresso1769 and mcb1800.

fix(dwc2): bound periodic intervals to HFNUM range

2026-09-02T14:18:44Z

HFNUM retains only 16384 host-frame positions, while valid periodic endpoint intervals can be longer. 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.

fix(dwc2): defer periodic DMA abort cleanup until halt

2026-09-02T14:14:26Z

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.
