Windows 10: Bluetooth 4.0 dongle not working - cannot roll back and cannot install drivers

I have a set of generic bluetooth 4.0 dongles. I have tried them several win 10 computers and they will not connect. In the device manager, I see the "red triangle" indicating the bluetooth has an error, however when I try to locate a driver, it says it has the "most up to date driver" not exact words as I am not on the laptop right now.Part of the challenge is that sometimes it manages to connect to the BT and then it disconnects just as quickly. Any solutions that might work?

Bluetooth driver error - USB dongle BT 4.0

I have bluetooth dongle that does not seem to be recognized by my win 10 system. Version 22H2 (OS Build 19045.3693) Here is the error : This device is not working properly because Windows cannot load the drivers required for this device. (Code 31) What I have tried :

• Device Manager and tried to reinstalled, disable, enable etc with no luck. turned the bluetooth setting off and on and still not luck. ran the troubleshooting for bluetooth and it does not repair anything.

When I went to the device website, it says that Win 10 will automatically plug and play and it doesn't need a driver: Cambridge Silicon Radio Bluetooth Driver | Device Drivers The device name is : CSR8510 A10 and in device managers it is Generic Bluetooth Radio with a yellow exclamation point. Here are some of the errors in the properties settings : Device USB\VID_0A12&PID_0001\6&1ff8b909&0&12 was not migrated due to partial or ambiguous match. Last Device Instance Id: USB\VID_8087&PID_0A2A\5&2CCCB896&0&2 Class Guid: {e0cbf06c-cd8b-4647-bb8a-263b43f0f974} Location Path: Migration Rank: 0xF000FFFF0000F120 Present: false Status: 0xC0000719 Thank you for looking. I am open to suggestions on what to try next.

 

Bluetooth USB Dongle

Ok so here's a question. I had a revelation today that: "Duh, my keyboard/mouse is bluetooth, shouldn't that be the same thing?" My goal here is to get my new Motorola HT820 bluetooth headphones to work with on my computer.

Keyboard/Mouse is Logitech MX5500 Revolution, bluetooth wireless, came with a USB dongle that they connect through. I tried today to get the headset to work, and it won't receive sound. I can get it "connected," but with complications. I'm using Windows XP, have Setpoint 4.7, and I've tried the following:

-Changed the radio settings to a bluetooth hub instead of locked to the keyboard/mouse.

-Clicked "Connect Other Devices."

- Paired headphones with windows. Windows connects correctly, the device reads connections, windows shows it as "already connected" when I try to connect it again. I click on Control Panel -> Bluetooth Devices, and I see the "Motorola HT820" listed as "Passkey enabled," but it doesn't say "Connected" like the keyboard and mouse do. Also, audio does play on the headphones.

-Click on Properties on HT820, and then on services, it does not show any services at all.

- Searched around google, logitech, motorola websites & forums to answers or help, nothing. Closet I got was logitech's "Bluetooth FAQ" which has the following paragraph (http://www.logitech.com/lang/pdf/bluetooth/bluetooth-faq.pdf):

"3.6 How do I listen to music wirelessly with a Bluetooth headphone?
All you need is a Bluetooth headphone and a media player such as iTunes or Windows Media Player 10. For optimal results, it is recommended you use a headphone with Bluetooth 2.0 Enhanced Data Rate, to benefit from the maximum bandwidth (up to 3Mb/s).
Please refer to our online "How To" documents for step-by-step instructions related to your specific device (www.logitech.com/bluetooth/howto)." [That link transfers you back to the same pdf document - it's a circle]

-I tried to install latest Widcomm stack from broadcomm's website, but it says it's not compatible with this dongle.

-Called Logitech Tech Support - got a total jerk girl who straight up said "No i can't help you." And then wouldn't give me the time of day after that.

I've read on threads on Logitech forum that people are using this headset with logitech dongles. Any help getting this connected? I just don't want to have 2 bluetooth dongles connected when I rly only should need this one. Otherwise I guess I'll just purchase one of the ones above, and use that to connect my keyboard, mouse, and headphones all in one swoop.

Sidenote: anyone have experience/knowledge with behavior when 2 bluetooth USB dongles are connected to the same computer?

 

Bluetooth 4 Driver for Windows 10

Hi Douglas,

There is a possibility that the problem is with the Bluetooth mouse or Bluetooth 4 dongle driver. To properly troubleshoot the problem, kindly verify the following queries:

• Have you tried updating the Microsoft 3600 Bluetooth mouse driver?
• Have you tried updating the Bluetooth 4 dongle driver?
• Have you tried removing or uninstalling the latest update and check if the same problem will occur?

We hope to hear from you soon.
