We recently upgraded from EX90s to DX80s. The problem we discovered is, with the EX90 we bought headset & mic's that used 3.5mm jacks. Unfortunately, there are no 3.5mm ports on the DX80, only USB. Is there a USB-to-3.5mm converter that can be used on a DX80? I found a converter, but it comes with a driver disk and since there's probably no way to install that driver on a DX80, I'm afraid the converter won't work.https://www.startech.com/Cards-Adapters/Sound/USB-Audio/USB-20-to-Audio-Adapter~ICUSBAUDIO
