Yes, it was a new instance. But I still have the ps list for that, and =
it turns out to be:
2193 1 3 3 0 ba526660 mdnsd usbxfer
and we've seen the stack for that one before.
I also had tracing on as before; the last little bit looks like:
usbd_transfer: xfer=3D0xbacb9d40, flags=3D0x2, pipe=3D0xbafa0780, =
usb_allocmem: use frag=3D0xc90acd80 size=3D4
usb_insert_transfer: pipe=3D0xbafa0780 running=3D1 timeout=3D5000
dwc2_device_start: xfer=3D0xbacb98c0 pipe=3D0xbafa0780
dwctwo0: urb=3D0x81365588, xfer=3D0x0
