What I'm looking for is something having grabbed the USB device. This is
hard to specify without knowing how the OWON does its USB, but for example
if it was serial I'd 'lsof | grep /dev/tty' and look for things using the
/dev/ttyUSB0 or /devttyACM0 device the OWON probably uses.

Since the OWON app has failed to grab the USB you're looking for other apps
that have grabbed it, ie not at the OWON app.
