Realtek bluetooth usb adapter RTL8671b

Readme.md

The CD that came with the device listed RTL8671B, but it's not on Realtek's website. Instead the manual points you to:

Adding visibility to @carkrueger 's comment below

If you look here: https://www.catalog.update.microsoft.com/Search.aspx?q=realtek+bluetooth+1.6.1015 You will find now: 1.6.1015.3014 from 11.01.2021

Direct download and the popup window for 1.6.1015.3014 didn't initially work. I ended up needing to right click the link and select Save target as. For it to work for me on Windows 10, I unzipped the cab file into a folder and then used Device Manager to look at that folder. Worked like a charm.

I've tried this method, however it did not work. It is possible that it was due to the previous 1.6.xxxx... driver that I already had installed. I will try to uninstall all drivers, fallback to the generic MS one, and try to install this one manually.

I am using the "Orico BTA-508", but by default Windows 11 installs and old relic version 1.6.1015.3018 for USB\VID_0BDA&PID_8771&REV_0200. I've tried several alternative drivers for the RTL8761B chip, from the 1.9.1051.30xx releases, from ASUS, TP-Link, etc. Some don't install at all, while those that install, cannot find nor connect to previously connected devices. 🤷 Could you please send a an archive with the latest modified driver for it? My main issue are BT connection drops when connected to a Sony DualShock 4 controller, using DS4Windows. The adapter is distanced from the PC with an USB 2.0 extension cord, however it did not help the sporadic behavior. EDIT: using Windows 11, so I would appreciate a modified .cab or any archive (.zip, .7z, ...) to test with my adapter no need to modify *.cab, just use manual driver update Please search Google for the "install device drivers manually on Windows 11" for the screenshoot guide 1. unpack/extract c1f14a17-4aed-40ff-85cb-7710d0244f42_4433154fbd9a4a8173ee994d24ee7eb640714562.cab file 2. open "Device Manager", choose the "Bluetooth" -> your "Bluetooth adapter" 3. Right-click on your "Bluetooth adapter", select "Update driver" in context menu 4. click "Browse my computer for driver" and "Browse..." to the directory, there you extracted *.cab file 5. Choose the "Realtek Bluetooth 5.4 adapter" 6. reboot you computer 7.

I've tried to do a complete clean install of all BT devices in Windows Device Manager, but the newer Realtek driver versions simply won't apply for the Orico BTA-508 adapter.

Even stranger, every single time Windows forces the 1.6.1015.3018 driver on every (re)install.
When trying to manually add the updated Realtek drivers, I can see their .inf is registered as oem202.inf and not applied to any devices, while the outdated Realtek one MS is forcing for me does not match that ID. The outdated v1.6 is registered as oem220.inf.

Screenshot attached:

EDIT: it seems I've figured it out. When browsing to the driver directory in the wizard, I had to use the "Have Disk" option, browse to the driver directory once more, and than it finally showed the device as a BT class 5.4 device. I was prompted that the driver was unsigned, bla bla, foo, yes install, and it worked. The adapter driver was finally updated to the latest version. Sorry for the post spam, but I was going crazy with it, and this debugging trail may help someone in the future.

The real question is: does the dongle actually have 5.4 features, or it's still a 5.0 with a newer driver ?

The real question is: does the dongle actually have 5.4 features, or it's still a 5.0 with a newer driver ?

Honestly not sure, I might be able to test it using some CLI tool, but I would need instructions.
The driver details report "HCI 13.56789 / LMP 13.51041", but whether this is actually true in the real world is TBD.
(In my case I don't really care, as long as the connection to my devices is stable now.)

EDIT: I can see that the second image in my previous post, after the update, failed to upload. I am reattaching it now 🤞
EDIT2: image upload failed again with "Access Denied", whatever. I think you get my point from text

Thank you so very kindly! This saved me 10 fold!

Got myself new 0bda:a728 device with true 5.4, driver 3013 installs automatically.

The driver works with my BT dongle with PID 0BDA-A725 (USB\VID_0BDA&PID_A725&REV_0200)
I had to force the installation as you have mentioned).

Did not have to. :)

The drivers should install automatically for these 2 VID/PIDs:

VID_0BDA&PID_876F ; BT54
VID_0BDA&PID_A728

but should be able to be able to be installed manually for the other 79 VID/PIDs in the PidVid_List.dat file (open with hex editor) but probably not with 5.4 functionality.

Good morning, is there any repository for this drive model available, but for installation on Linux?
