SABRENT USB Bluetooth 4.0 Adapter Dongle for PC Laptop Desktop Computer Mouse Keyboard Headphone Controller, Support Windows, Mac, Plug and Play (BT-UB40)

I'm quite a few years back now, I still run my programming learning in a Raspberry Pi 2 Model B. This being the version without built-in WiFi nor Bluetooth. I scoured the site for a compatible Bluetooth dongle and noticed very few offer support for Linux, let alone mentioning anything about Raspberry Pi.I am relieved to say this works for Linux, including the Raspberry Pi without any hassle. I'm still an amateur when it comes to programming and Linux. I hopefully plugged this in, a super small form factor USB with strong plastic and metal build. The dongle worked instantly!! As shown, the Bluetooth can be turned on, and quickly presents an array of devices to connect to. There is an option of discoverability which I did not need. I was still sceptical as to whether this would connect to my Bluetooth keyboard. It sure did! Once I got my keyboard to show and connect as a keyboard device, I went typing happily away. So far I have not faced any connectivity issues and the connected devices stay saved for the next session for easy reconnecting.In all, a Bluetooth dongle- amongst a mammoth market of dongles, that works as precisely promised and fairly priced. The dongle is plug and play for Linux and stays connected without issue.

I have just refurbished an old Toshiba Equium P-300-16T. I replaced the hard drive, to a ssd, and upgraded the ram ( Can't go above 2gb on this laptop!! ) I installed windows 10 on the ssd, vista was on the old hard drive. This laptop is 32 bit, so installing windows 11, would not be viable!The laptop does not have Bluetooth, so after researching the available usb adapters, I opted for this one, for its small size, and the manufacturers reputation.When I received the adapter, I installed the cd driver, I followed the instructions, as written. I tried to connect the Microsoft phone link, but failed miserably! Then a printer, ( Epson ET-2850 ) not recognised! I tried connecting other Bluetooth devices, but not one worked! I looked online, at various computer sites, I looked at the Sabrient site, but I could not find a solution, Maybe my fault for not looking hard enough!I was on the brink of giving up, and returning the thing, when I noticed, that on the reviews, some reviewers were not using the cd, and just plugging in! So I uninstalled the cd, rebooted, and plugged the adapter in, and it worked straight away, with no problems whatsoever!So, If I had ignored the instructions, ( I normally do! ) and plugged the adapter in, without using the cd, I would not have had the above problems! I would think, that Sabrent know about this, so they should say that the cd driver is not needed with windows 10! Especially with someone like myself, who know very little about computers!I must say though, this device does work well, but try it without using the cd driver first.

I have this connected to a windows 10 PC to work with a 8bitdo Pro 2 controller and speaker.I am using the standard windows 10 drivers as I tried to use the drivers from the company website, those drivers would not get it recognised. I uninstalled and just plugged the gadget in and the built in drivers recognised it. It does however sometimes lose the bluetooth when starting the PC and have to take it out and plug it back in (use same slot all the time). I have had it working on several bluetooth speakers.My main reason to buy it was to use with the 8bitdo Pro 2 bluetooth game controller using Batocera (Linux) on the same PC. This works brilliantly and have no issues so for what I bought it for, I have no problems and very happy.

I am rather impressed with the quality of this mouse.Working primarily in spreadsheets I find this mouse to be light, nimble, and accurate. I've used the also popular INPHIC (around the same price) which is a very well-built mouse but it's more of a tank, whereas this can click around the page with ease.Strengths:- easy to move around quickly- mouse click is standard/solid (however it's not silent like INPHIC)- comfortable to use- no side buttons which I find just get in the way- battery saving mode after period of no use- well built- USB charging (no need for batteries)Weaknesses:- could possibly be slightly more ergonomic (it's not uncomfortable, but some computer mice shape the natural curve of your hand a little more when you're using it which results in less need to adjust your hand now and then)- probably suits people with small/medium hands, people with larger (long) hands might find their fingers extend beyond the front of the mouse (where you click) when at rest and would need to re-adjust frequently- the wheel is standard but the one on the INPHIC definitely feels of better quality (you get used to it though so isn't really an issue)- after an extended period of time the mouse, even though still 'on', shuts down to save battery and does not automatically come back to life as you move it, so you need to flick the switch on the underside of the mouse to off, wait a few seconds, and then switch back to on again to get it back working (again pretty minor)All in all I am very happy with this purchase, especially at this price.(have been using for 3 weeks (Mon-Fri) and have not needed to re-charge yet)
