Wireless headset USB issues

I have an old Logitech H760 headset that I've struggled to get working reliably for years. It's sat in a box for ages, but now almost all my meetings and phonecalls are online from home I need it again.

When I plug into my main PC it doesn't connect. Windows recognises it, installs a driver and shows it under 'Bluetooth and Other Devices.' But the ilttle green light on the dongle and the headset just flash endlessly and there is no sound.

I've discovered that it works on my Raspberry Pi and sometimes on my laptop. In fact I have just found that it worked on one USB port on my work laptop for about 5 minutes and then stopped (lights went back to flashing). Since plugging it into the other USB port on my laptop it has now started working again. When I plugged something (a Wacom tablet) into the other port, the headset stopped working (lights turned off entirely), but when I unplugged and plugged back in it came back. Under Device Manager / H760 / Properties it says, "Driver Management concluded the process to install driver wdma_usb.inf_amd64_d4f7f6fd843ed0fd."

Given that it clearly works in some situations, I assume this is some sort of USB driver conflict and not a hardware issue. Can anybody suggest a process to try and resolve it? Hopefully the laptop thing gives some clues. I have tried adding as a generic bluetooth device, but it is not recognised so presumably the dongle is creating some sort of locked-down bluetooth connection.

Thanks in advance.

I would first try a different USB port, just in case. Then I would open Settings -> System -> and make sure the wireless headset is the default output device. If again you have no sound, then you may use a driver tool such as Snappy Driver Installer to update the driver for you. Have you checked at Logitech's site? The driver for Windows 7 might work.
