I quickly tested this with the following results:
- Plugging the device in without opening it suspended my device and the
root hub- good!
- Starting krecord, using the /dev/dsp interface, works and the
microphone sounds fine.
- However, the device never suspends after closing the application.
I will investigate further later.
Cheers,
