USB Headset not recognized as Audio Device, but shows up in lsusb

For starters I'm running Kubuntu 20.04 with kernel 5.4.0-90-generic. I have a new headset, a Jabra Elite 85h. I've had previous Jabra headset and audio recording and playback over USB worked fine. However, this headset will not work as an audio device, but it is recognized as a USB device.

running lsusb, it shows up as:

Bus 001 Device 007: ID 0b0e:248a GN Netcom

Running sudo lsusb -v -d 0b0e:248a gives the following output:

The phrases "audio" or "stream" are not mentioned. The device does not show up in alsamixer nor pulse audio control with pavucontrol.

aplay -l | grep card does not list the headset. cat /proc/asound/cards doesn't list it either.

I've tried deleting all my pulse configs in ~/.config/pulse, but that didn't fix anything. I've also updated the headsets firmware via the Jabra app, but that didn't change anything.

Jabra's official stance on audio over usb on Linux is that it should work at a basic level, and that has been my experience with Jabra headsets in the past. But this one is giving me a particularly hard time even showing up as an audio device.

Any help would be much appreciated.
