Noisy warnings in 1.33.2?

[Aleksander Morgado]

Hey Andy,

> In the latest version 1.33.2 of libqmi I'm getting strange warnings. It's very noisy and not useful. It can be silenced with --silent, is this normal?

What does this command return?
$ realpath /sys/class/usbmisc/cdc-wdm0/device/driver

If I had to bet, you're probably not using the upstream qmi_wwan
driver, but a different vendor-provided one instead. Is this the case?

If you want to silence the warning you can also pass --device-open-qmi
explicitly.
