Bluetooth 4.0 USB Nano Adapter - Windows XP/Vista/7/8/8.1/10, Mint, Ubuntu, Fedora, openSUSE, Lubuntu, Zorin, BackTrack5 R3, Kali Linux, Raspbrian Wheezy and OpenELEC

Works on Linux Mint (Ubuntu), yippee

I bought this for a Toshiba laptop that didn't come with a bluetooth adapter installed when built. Old, it was shipped with Windows 8.1 which is supposed to have native support for Bluetooth 4.0. Unfortunately since the unit wasn't shipped with Bluetooth it didn't have the drivers so I had a bit of trouble connecting devices. I finally changed the way Windows Update would run and let it automatically check for updates and that prompted it to install a Servicing Stack. And had to go into Control Panel to change settings. Everything I needed to do I found while searching on the Internet. Once it did that I could connect a Microsoft Surface BT4.0 keyboard and a Nullea 505 Trackball. The only issue is with LE devices and randomization which can't be tweaked in Windows 8.1 but that isn't anything to do with the adapter. I have the same Toshiba laptop dual boot with Linux Mint and it works much more reliably with Linux once I made some tweaks in the bluetooth controls, again related to LE, MAC randomization and privacy. Also plugged it into a Lenovo mini tower that didn't come with bluetooth internally, was Windows 7 upgraded to Windows 10 and had no issues at all, same devices all connected right away without any manual configuration. Not the least expensive bluetooth adapter but if you want something that is a contemporary of an older machine to increase your odds of success it is worth a few extra bucks.

Using Linux Manjaro KDE i first plugged it in the USB 3.0 port on a HP8560P laptop. Laptop recognized the adapter without having to install any driver and had no problem pairing Sony WH-1000XM4 Wireless headphones. The audio keep cutting in and out when listing to music in bedroom about 18 ft from laptop and other rooms in a small house. The signal only had to go around one corner to get to bedroom. I then plugged it into a USB 2.0 port on laptop then audio did not cut out in any room in house on 1st floor. Did a google search to see why audio keeps cutting out for bluetooth headphones on usb 3.0 port. It said audio cuts out because USB 3.0 ports emit radio frequency noise in the 2.4GHz spectrum, which directly interferes with Bluetooth signals. This interference causes data loss between the dongle and headphones, resulting in choppy audio. Moving the adapter to a USB 2.0 port or using a USB extender usually fixes this. The sound quality is excellent. Like the reviews said it is plug and play on Linux. I recommend it but use USB 2.0 port or a short 6” USB 2.0 extender cable connected to USB 3.0 port which will also stop radio frequency interference and audio should not cut out. When watching videos on Youtube in 1080P HD video quality the audio is in sync with their lips, don’t notice any lag with my Sony WH-1000X4 wireless headphones. Maybe it depends on what version bluetooth the headphones and computer are using?

Nice device

Haven’t tried linux yet but plug and play immediately under Windows 10. Manufacturer provides excellent support. Quick in responding.
