After recent upgrade of my windows Jabra Evolve 40 Duo headset stopped working all of a sudden.
Same headset works on different PC's and Laptops as expected but on this particular laptop it stopped working. It does not detect the device when I plug it.
Attaching the system information for reference.

I had similar situation recently with Jabra after PC woke up from sleep.
Luckily it was fixed after reboot.
Did you try to reinstall Jabra Direct?
