Yes. It is completely useless for already supported devices.

But verifying new devices is currently a lot of hassle due to missing support for new_id in qmi_wwan (generic problem with usbnet drivers), and the strict probe in cdc-wdm (will refuse any interface with more than 1 endpoint). A libusb based tool allow users to quickly test all interfaces on a new and unsupported device without having to patch and build a new driver first, but that is all it is useful for.  So it might not be anything for libqmi-glib. The perl script will do after some refinement.

Getting proper new_id support in qmi_wwan would be a better solution, and would probably benefit other usbnet drivers too. But I still have not found an acceptable solution to that problem.
