USB disconnect issues on HP ZBook 15 G3 via Thunderbolt docking station

HP ZBook 15 G3
Microsoft Windows 7 (64-bit)

I am using a Jabra UC Voice 550 Duo USB headset (Skype model) with Windows 7, for business communication. Or, at least, that was the intent: The reality is that if I use any ports on the docking station, I lose connectivity in the middle of a call. Several Skype chats started out okay, and then the microphone on my end simply stopped working (I could still hear the other party.)

 

Also playing audio (Youtube via Google Chrome) has also resulted in eventual loss of playback. I have had to plug the USB headset directly into the laptop, in order to obtain glitch-free audio (via the on-board Intel USB root hub). The ASMedia USB root hub in the Thunderbolt docking station seems to be the culprit: I have two HP Z24n monitors plugged in via DisplayPort, and it makes no difference if I use USB ports on the monitor vs. directly plugging the headset into the Thunderbolt docking station itself.

 

Since the laptop has limited USB ports, I would like a solution to this problem, please. The ASMedia root hub is running on driver version 1.16.33.1, dated 04.02.2016.

 

One last thing: I got driver software for my Z24n monitors on CD-ROM, but hardly any notebooks are shipped with CD/DVD drives these days - and I could not find an online copy of the software, so I could install the display profiles.
