StarTech.com Bluetooth Adapter - Mini USB Adapter - Bluetooth 2.1 - Class 1 EDR - Bluetooth Receiver (USBBT1EDR2)

Auto detected the device and I was able to immediately pair my keyboard and mouse combo.

Needed it to connect a Scuf Instinct Pro controller wirelessly to my pc running ChimeraOS on a spare nvme to game occasionally on my PC. Was recognized immediately and connection is strong and stable.Also, I booted into my main distro (Ubuntu 22.04) and connected my Sony XM4s (WHs). Flawless sound and stable connection. Haven’t tested the “hifi” audio codecs (aptx and such) because haven’t been able to compile the plugins in my first try (something about pipewire version) however audio over SBC is perfectly fine.Anyway, wanted to share my experience specifically for Linux. Windows probably works great also.

Has an effective range, when streaming music to a speaker or being streamed to, of about 15 feet. After 15-20 feet the music starts skipping and chopping out and eventually the connection is lost altogether.I tried connecting the StarTech to various Bluetooth devices (iPhone, iPad Air, JBL Flip 3) and it couldn't maintain a reliable connection through one wall, or one window (with direct line of sight to the adapter). Even without anything between the adapter and the source, effective range was 15-20 feet.To make sure it wasn't the JBL Flip speaker, I connected the speaker to my iPhone via Bluetooth and had someone go about 45 feet across the street and the music played and never skipped a beat and ahowes no signs of being close to its maximum range.The computer in question was one that I had built for my mother. It runs Windows 7 64 bit, and all drivers and firmware were installed and/or updated for the StarTech Bluetooth adapter.If your goal is to use a Bluetooth mouse/keyboard, this might work (I'm not sure about input lag as I was only testing speakers), but if you are looking to use this to connect a centralized speaker to your computer so you can listen to music in other rooms, be aware that it has a fraction of the effective range that is advertised.

Works well on my 2012 Mac Pro. No need to install drivers. You have to turn off bluetooth, plug it in, turn bluetooth on and OSX will recognize this adapter.I'm using it with Apple's Magic Mouse, and Trackpad and there's less lag than using the built-in bluetooth device.Also works with my Airpods, however the range is very limited maybe 25 ft. and even the mic works decently. The Airpods were unusable through the built-in bluetooth.

Works perfectly with my hackintosh Ventura.My old MacBook Pro 2012 works whit this dongle as well. I can use my apple magic mouse again.

Works great with Linux. As of Janaury 4, 2025, I'm using the latest version of Fedora Linux, and it was plug and play baiscally. Picked it up instantly and paired my bluetooth headphones with no issue.

Does not work on Linux Mint 22.1. Any search will tell you the Bluetooth on Linux is often problematic. This one is no different.Might be fine on another OS

My Mac mini 2018 had issue with mouse lagging. Especially when I am downloading and uploading large files, the lagging came to a point where my Apple Magic Wireless Mouse is unusable. This is due internal WiFi chip is interfere with internal Bluetooth chip. My guts feeling is that internal WiFi chip and Bluetooth chip are a one combo chip. When Wifi is heavily used, MacOS reduces internal performance to prevent the chip overheating and melting which it actually happened to my Dell Alienware compact PC. By adding this external Bluetooth USB, it solves the mouse lagging issue. The is Bluetooth USB will override and disable internal bluetooth. So you will need to turn off-and-on on both Apple keyboard and mouse in order for the new Bluetooth USB to discover them. You will need also to shut down your Mac first, plug this Bluetooth USB in and then start up your Mac.
