UB5516: harness complete (phase C = fixed build rerun, see run.fixed.log)
UB5516: DF-5516 ubser attach-pin harness (USB_DEFAULT_TIMEOUT=5000 ms, usbdi.h:87)
UB5516: production driver "ubser" compiled into harness (registration neutered)
UB5516[A]: --- insertion: ubser_attach runs on the per-bus USB explore thread, GET_NUMSER first (ubser.c:242-251) --- (t=0)
UB5516: EP0 bRequest=0x01 wLength=1 (5000 ms timeout): device silent -- NAKs until timeout
UB5516 DEV: failed to get number of serial ports: USB_ERR_TIMEOUT
UB5516[A]: explore-thread occupancy 4908 ms; attach ABORT via verbatim `goto detach' (production target ubser.c:296-298: ubser_detach + ENXIO)
UB5516[B]: --- insertion: ubser_attach runs on the per-bus USB explore thread, GET_NUMSER first (ubser.c:242-251) --- (t=0)
UB5516: EP0 bRequest=0x01 wLength=1 (5000 ms timeout): device answers at just-under-timeout
UB5516 DEV: found 4 serials
UB5516[B]: explore-thread occupancy 4811 ms; attach CONTINUES past the block (usbd_transfer_setup next, ubser.c:264)
