I recently bought myself some Sony Bluetooth earbuds for my phone, but I was keen to see if I could connect them to my PC too – so that I could use them in conference calls, for example.
But my computer didn’t have Bluetooth. So I bought TP-Link UB400 Bluetooth Adaptor online, because I’ve used and liked their stuff before. But when I plugged it in it didn’t work! Windows 10 kept telling me I didn’t have Bluetooth installed.
I went to the TP-Link FAQ for the UB400 – but nothing they suggested worked.
After a bit of Googling, I went to the Windows Device Manager, looked at the Universal Serial Bus controllers, and disappeared down a rabbit hole trying to fix the “Unknown USB Device (Device Descriptor Request Failed)” problem.
And only then did I go to the “CSR Bluecore Bluetooth” driver that also appeared on the list of Universal Serial Bus controllers when I plugged in the dongle. As an experiment:
- I right-clicked “CSR Bluecore Bluetooth and selected “Update driver”
- Clicked on “Browse my computer for driver software”
- Clicked on “Let me pick from a list of available drivers on my computer”
- Picked “Generic Bluetooth Adaptor” in place of “CSR Bluecore Bluetooth”
- Clicked “next”
and suddenly everything worked!
So that’s my solution! I hope it works for you too.
Thank you! I’ve had my UB400 dongle “disappear” after I moved it to another USB port, and in Device Manager it would come out as “hidden”, with all the device icons greyed out. What I could find on the TP-Link site was either useless or too annoying (e.g., installing the their CSR driver, which wasn’t made for Win 10, and was very annoying to use).
Long story short, your solution worked immediately, and restored my settings, and access to the paired devices.
Awesome after some issues with the device, suddenly fixed it with your solution!
Thank you so much, I actually reset my whole PC for this.
had to comment on this, you saved me a trip to best buy and more money, THE ONLY SOLUTION THAT WORKS!
thanks
You are fuckin amazing bro. I did so many stuff to restore that shit. Like, really, so many. This was my last try to fix this.
Thank you so much!
You are awesome! Thank you for the solution and Merry Christmas!
Any idea if I don’t have the Generic Bluetooth Adapter in my driver list? Thanks!
No idea, I’m afraid. Is any kind of Bluetooth adapter listed?
Thank you very much. Whithout your suggestion I was not able to find the solution.
Thank you so so much. I’ve been looking to solve this problem for a few hours now and your solution is the only one that worked. Thanks for the article!
You my friend is a life saver! Of all the tips and guides that I’ve encountered yours made the most sense and helped get my bluetooth to work!
This works, I’ve been tearing my hair out wondering if the issue relates to type of USB port or if I’m using the wrong driver but unable to find another. Many thanks for the concise and clear explanation. Perhaps you can go on to explain the merits of proportional representation with equal brevity! Merry Christmas and a happy and healthy new year to you and yours.
Thank you very much 🙂 🙂 🙂
Thanks man. You ARE now my DAD!!!!!!!
This worked for me after experiencing the disappearing issue. Thanks!
Give this man a medal !
THANK YOU!!! JESUS CHRIST, THANK YOU!
Your solution was perfectly. I bought it by Amazon.and after several days of trying to get the d***mn thing working with no luck I decided to send it back and told them the dongle was not recognised by Windows, but they told me keep the thing I will send you another one, at first of course with the same result. But after reading your solution I now have two working dongles. You´re the MAN, thank you for the advise.
thank you very much. Your solution was perfect!
Worked a treat. Many Thanks!
My warmest thanks. Your solutin worked perfectly also for me.
You save my device! Works perfectly now.
4 months ago I buyed this tp link, thank you so much !
Martin,
Thanks your suggestion worked for me….for connecting UB-400 with KT480 keyboard in Lenovo Laptop L470.
Your Trick 1000% Accurate & Working…. I would say now it’s works “LIKE A CHARM” on Windows 10 64bit Thank you….
For me i didn’t work… it does not let me install this driver. Any ideas how to fix? Help asap ;p
Hi Ale
It’s important to click on “Let me pick from a list of available drivers on my computer” – i.e. not try to install a new driver – but use one that’s already installed.
Martin
Brilliant, worked perfectly.
Awesome! I used my UB400 for sometime, all of the sudden disappeared, after a few days troubleshooting and surfing the web for ideas I ended up here. Your solution made for me. Thank you so much!
Thanks for this solution, worked perfectly first time. Had previously spent hours trying to get bluetooth to work.
Billiant!!
Oh my god finally solution that works. I was dealing with this crap for years on lot of devices and BT cards/dongles. original drivers didn’t work, default windows drivers that suppose to be the same thing as what we did in this post, but now it magically works. Thanks mate, you saved me from ending in asylum.
Brilliant !
thank you from Paris, France
I have windows 7 and bought a tp-link UB4A bluetooth adapter. I tried your hack, didn’t work. Any other solutions?
Sadly not! I stopped when I found a solution that worked for me. Have you tried the TP-Link support community or the support pages here.?
omg yes I was about to throw this PC out the window. i knew it was going to be something easy and stupid
Omg finally working. Thank you so much. I was getting it replaced. 🙂 Good day.
Thank you! This solution was the end of hours long troubleshooting. I was so relieved this simple fix worked. Thanks so very much.
I love u, this worked perfectly
Thanks man. I tried everything to connect X-box controller. This is the perfect!!!
This completely solved my issue! Thanks so much!!!
thank you thank you that’s the solutions !…
congratulations…
This worked like a charm for me after failing to use the FAQ and failing to connect. Thanks so much!
THANK YOU!!!! lol this is wild that you are helping so many people with this and this is the only place ive found this solution on the WWW. Had this working out of the box for about 6 months, then all of a sudden it stopped recognizing. I thought it went bad because nothing worked. After 2 days and freaking out fearing id have to wait on a new one shipped i found this. I installed CSR bluetooth from TPLink website, (was just plug and play before – no downloads out of box) and it was conflicting with windows bluetooth i think. Once I tried this fix, however, it started working instantly and all my devices are back working. THANKS AGAIN!
THANK YOU VERY MUCH!
IT WORKS FINE!!!
It helps a lot
Amazing! Thanks!
