Since upgrading (from 12.04) to 14.04.1, when I hotplug my USB headset, it does not work right. It won't show up in capture controls, sometimes not even in playback devices. I have to fiddle with pavucontrol to even get it to do that. When it does, it thinks it's an input-only device. It tries to use "Monitor of GN 20000 USB Analog Stereo" for input but of course nothing comes over that. When Skype is active, I can't even select the "non monitor" version of the GN 2000. But, if I go into pavucontrol, show all input devices (which then includes the GN 2000 monitor), un-mute it, I can then select "GN 20000 USB Analog Stereo" as my input device for Skype (in pauvcontrol), and the GN 2000 once again shows up in the "capture devices" in the audio mixer.
Also, sometimes the GN 2000 comes up in pavucontrol as "Analog Stereo Output" and the only other options in the drop-down are outpt-related, no option for input; this is sometimes fixed by removing and plugging the device back in...and sometimes not.
If I reboot, it all comes up properly. 'pactl exit,' and restarting pulse audio seems to fix it (the stereo duplex issue), but then that causes other problems (like a Skype hang).
Doing a 'pactl list' of the working and non-working configs shows that lines having to do with the GN 2000 and "output: something + input: something" are missing in the non-working config...but we kind of knew that.
I'm really at a loss here.
This is my hardware:

It is the GN Netcom that has issues. Even after resume, it will show up in lsusb.
