Review: Still Rock Solid After 8 Years—Reliable Bluetooth Adapter for Everyday Use - I picked up the ASUS USB-BT400 Bluetooth adapter way back in 2018, and honestly, it’s still running perfectly in 2026. I’ve built and upgraded a lot of PCs, and this little adapter just keeps working. Connectivity is solid—I haven’t had issues with my headphones, headsets, mice, or controllers dropping out. Everything just pairs up and works, even when I’m swapping devices around for gaming or work. The only exception is my Fire tablet, but that’s not really the adapter’s fault. Some devices have built-in security (like locked bootloaders or pairing restrictions), so they just won’t connect to anything that’s not an approved peripheral. That’s a tablet-side thing, not a problem with the ASUS adapter. Latency has never been an issue for me, even with my high-DPI Razer Basilisk gaming mouse. No noticeable lag, even when I’m gaming or moving between devices. If you’re chasing the absolute lowest latency for competitive gaming, maybe a Bluetooth 5.0 adapter would have an edge, but for my setup, this one is honestly great. I don’t see a strong reason to upgrade when everything just works. It is a great value, it's supported by windows out of the box, it's very small too. The adapter is still going strong after years of daily use, no defects, no weird disconnects, nothing. It’s just a solid, reliable piece of hardware. For anyone needing Bluetooth on a desktop or upgrading an older PC, I definitely recommend it. Still using mine in my current rig and it hasn’t let me down. PC builder, gamer, and tech junkie approved!
Review: Works great, but make sure to install official drivers for best quality! - Works great with my google pixel buds. I tried a different USB adapter that gave me more range, but terrible audio quality. This adapter on the other hand has a range of maybe 15 feet, but excellent audio quality for my wireless ear buds. And it also works on linux!

## Questions & Answers

**Q: Will this work on windows 10?**
A: ASUS now has new (2021-12) drivers for Windows 10 and 11. (See the ASUS HelpDesk Download link in post above.)

**Q: Can this transmit voice through a built in microphone from the wireless headset to talk to people if I use it for gaming?**
A: Yes

**Q: i have an asus laptop that doesnt have blue tooth is this what i need to use wireless headphones with my computer**
A: Well, Watch out because even if you have an asus laptop this product is useless for Windows 8 or 8.1. I did call the support number and they confirmed that it wasn't happening and that Windows 8/8.1 blows. They suggested I downgrade to Windows 7. If I do downgrade to 7 it won't be to get this $15 part to work- it will be to stop the nightmarish experience of Windows 8. The number for support is 1-812-282-2787. And yes (I'm looking at you, smug sophisticated tech geeks) I should've known better, but I didn't and I hope this saves someone else a little trouble and $14.99. Dang that was a disappointing waste of time. Good luck.

**Q: Does this do multiple pairing?**
A: Yes, you can have multiple pairings with this device.

### ⭐⭐⭐⭐⭐ Works good in Linux with some effort
*by F***C on February 21, 2024*

I bought this to interact specifically with ble 5.0 devices from my PC and possibly some SBCs. This was a huge pain to install but here's what I did which will hopefully spare someone else the agony. The documentation on the Asus site is pretty abhorrent. It's mostly Windows oriented, and even for Windows the documentation is awful and you are pretty much on your own. It's a "plug and pray" situation with this thing until you get it setup correctly. Yes, it's supported in Linux so should work on Raspberry Pi as well. Once it's running it's actually really nice so far. Also the drivers include the source which is a win. How I got it working (old Ubuntu 18.04 with kernel version 5.4.0): First, download the driver from the Asus website. Second, blacklist all default bt drivers by creating the file /etc/modprobe.d/bluetooth-blacklist.conf then add this to it: blacklist btrtl blacklist btusb blacklist btintel blacklist btbcm This was necessary for me as the two devices were fighting for attention so to speak. It may not be needed for you (you can skip this and try it later if needed). Third, reload the kernel module settings (part of the above step): sudo systemctl restart systemd-modules-load.service Note that you will probably lose your bluetooth control panel, but you can undo this later by deleting the conf file then reloading the settings again. Fourth, install the driver after unzipping it and cd'ing to the folder: sudo make install INTERFACE=usb Fifth, you must copy the firmware to the correct location. Go into the folder /rtkbt-firmware/lib/firmware inside the driver folder and copy these two files to /lib/firmware/ on your system: rtl8761bu_config rtl8761bu_fw Now see if the device is listed: hciconfig -a the device should appear there. If not, unplug the device then turn bluetooth off then on. Depending on your distro, it could one of these (Deb/Ubuntu/fedora): sudo service bluetooth stop sudo systemctl stop bluetooth Plug it back in, run hciconfig -a again and it should be working. If still nothing, run: lsmod | grep bluetooth and see if 'rtk_btusb' is listed next to bluetooth (with some others, probably). If so then the driver is probably installed. Now let's see if your firmware is correct: Type dmesg and see if there are any errors there. If you are seeing a cryptic message in dmesg like: rtk_btusb: fw name is rtl8761bu_fw rtk_btusb: This is not 8723a, use new patch style! then the firmware has not been copied to the correct folder which will prevent it from working. Locate the correct firmware folder for your distro then redo the steps from that point again. Hopefully it should be running now. Now you can play with it in bluetoothctl. Type bluetoothctl then type scan on and see if there are any devices. Type help for a list of commands... have fun! If all else has failed, remember to register your device on the Asus website then you should be eligible for support (didn't try this, your mileage may vary).
