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? -- Best regards, Yuan Chao -- Best regards, Yuan Chao _______________________________________________ Power mailing list [email protected] http://www.bughost.org/mailman/listinfo/power
