Issue with Razer Nari Ultimate Usb-Dongle

Hey! I got issues with my Razer Nari Ultimate Usb-Dongle: When i plug it into any computer, the pc only detect it as "Avnera AV6301" idk why. I've got this problem now since 6 months and didn't get any answer yet! I've bought some cheap Headset for 20 bucks but there's no answer from your support. If I'm not getting a answer in the next 4 days, I'll never ever consider buying anything from razer anymore! I thought with those "premium" headset I'll get some support but this ain't the fact... The 1 year protection is now over and I wont get it repaired for free so why is this so hard to comment a support post???Is this some marketing s*it? Yours sincerely
