[autotest] Select USB explicitly in USB test

In audio_AudioBasicUSBPlaybackRecord.suspend, some DUTs will detect MIC
again after suspend so MIC will become the main input node. The test is
for testing recording after suspend so it should check and select the node
explicitly.

Log down more information for future debuging.
