Comment 5 Pete Zaitcev 2005-05-14 04:25:18 UTC
It appears that the device does not let the port to detect a plug,
maybe it resets too long after the power is applied to the port.

Please try to plug the audio into a socket of an external hub, preferably
a powered hub. Monitor might work. Perhaps those have +5 at all times.
I don't remember what the spec says about it.
