Review: Works with macOS - Bought to add Bluetooth 4.0 support to a 2009 MacBook Pro (built-in Bluetooth is 2.1+EDR) running OSX Sierra (10.11.6), to use a Microsoft Mobile Mouse 3600 which requires Bluetooth 4.0. As other reviewers have said, it is plug-and-play - I was able to immediately pair the mouse, and the cursor movement was smooth. I had a couple of times where the cursor movement became jumpy; disabling the built-in Bluetooth with this command in Terminal and then rebooting fixes that issue: sudo nvram bluetoothHostControllerSwitchBehavior=always Review: Used for PC - Works well :) - Needed a Bluetooth dongle for my PC so that I could connect my Sony Earbuds to the PC. Just plug it in and that's it. ## Features - Bluetooth 4.0 – Applies the latest Bluetooth 4.0 with low energy (BLE) technology and it is backward compatible with Bluetooth V3.0/2.1/2.0/1.1 - Driver Free – Plug and Play for Win 8, Win 8.1, and Win 10 - Nano-Sized – Ultra-small for convenient portability with reliable high performance - Supported Operating System – Supports Windows 10/8.1/8/7/XP ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07NQ5YGDW | | Best Sellers Rank | 14,315 in Computers & Accessories ( See Top 100 in Computers & Accessories ) 39 in Wireless Access Points | | Box Contents | 1 x UB400 | | Brand Name | TP-Link | | Color | Black/White | | Compatible Devices | Laptop, Desktop, Tablet, Smartphone | | Compatible Operating System Family | Windows | | Country of Origin | Netherlands | | Customer Reviews | 4.3 4.3 out of 5 stars (90,504) | | Data Link Protocol | Bluetooth, USB | | Data Transfer Rate | 0.4 Megabits Per Second | | EU Spare Part Availability Duration | 3 Years | | Global Trade Identification Number | 06935364099664 | | Hardware Interface | Bluetooth 4.0 | | Item Dimensions L x W x H | 19L x 7W x 15H millimetres | | Item Weight | 10 Grams | | Manufacturer | TP-LINK Deutschland GmbH | | Manufacturer Part Number | UB400 | | Minimum Required Operating System Version | Windows XP | | Model Number | UB400 | | Unit Count | 1.0 count | ## Product Details - **Brand:** TP-Link - **Colour:** Black/White - **Compatible Operating System Family:** Windows - **Compatible devices:** Laptop, Desktop, Tablet, Smartphone - **Data link protocol:** Bluetooth, USB - **Data transfer rate:** 0.4 Megabits Per Second - **EU Spare Part Availability Duration:** 3 Years - **Hardware interface:** Bluetooth 4.0 - **Item weight:** 10 Grams - **Product dimensions:** 19L x 7W x 15H millimetres ## Images ![UB400 Nano Bluetooth 4.0 USB Dongle Adapter for Computer, Laptop, Headphones, Speaker, Keyboard, Compatible with Windows 11, 10, 8, 8.1,7, XP, Black - Image 1](https://m.media-amazon.com/images/I/51YC-cv2atL.jpg) ## Available Options This product comes in different **Style** options. ## Questions & Answers **Q: Does this work with a Microsoft wireless keyboard and mouse?** A: I would think so I’m using mine to connect printer to my pc. **Q: Can you use this to connect an iPhone to a printer?** A: I am not sure about the iPhone.
