I have an USB audio deivce and I wan't to detect if it is inserted.
I have tried the "QAudioDeviceInfo" class, but it seems the class can only obtain device name which is useless for me.
A champion is someone who gets up even when he can´t.
you can try libusb, like described in this thread

Hi @raven-worx ! Thank you for your reply . I think there maybe a easier way which using the win32-API. but I think your solution is the best .
