The USB auto-suspend does some improve to me. However, I recently
found that it seems that actually it's NO_HZ (instead of USB_SUSPEND?)
that cause some problem on my USB speaker phone. The speaker works
fine but no sound from the mic. Sometimes the snd_usb_audio doesn't
initial the hardware properly (?) w/o any warning or error. Just
wondering if this is due to some timing issue. Don't know if anyone
met similar problems too?
