    Works great for PC, not well for PS5
    Installed on my PC which had no Bluetooth on the motherboard and it synced to my Bluetooth headphones immediately! Tried the same on ps5 and get the same error like I do other Bluetooth devices that are not PlayStation branded. I saw someone had success in a review I did not.

      Does what it's supposed to do!
      Easy to install.
      Tip 1 Lag: I had a very slight lag, put it on a a non fast charging port and that pretty much fixed it.
      Tip 2: Distance: It didn't make it to the bathroom but already had a small extension for ports and just pointing it that way fixed that.
      If you don't have blue tooth on your computer for some strange reason like me, THIS is your best option.
      Great price, works perfect for blue tooth earbuds, which is what I got it for.

      recently been having disconnecting issue with my pc with controller (bluetooth) it will disconnect from an short range. buying this product really did help with that issue it, works from a far as well and i’m glad for it too work just make sure you read the instructions because it instructs you to disconnect bluetooth within your pc and to utilize the USB receiver as the primary device for Bluetooth. would recommend for people to buy this if you had the same issue as well.

      4.0 out of 5 stars A big upgrade from my prior USB BT Adapter
      Reviewed in the United States on May 14, 2014
      Style: Bluetooth 4.0Verified Purchase
      So like everything... it's not perfect. But given the price point, I'm not complaining. Just to be clear so people have complained about streaming audio from this unit, and that is not something I have done, so if you are looking for an opinion on that you can stop reading now.

      My prior BT adapter (non-ASUS) always had problems keeping the connection to my BT Keyboard. And I would have to unplug it and plug it back in. This was a horrible inconvenience. This unit does not have that problem at all, which is the biggest reason I like it, but some of the other features have been great as well.

      While I haven't streamed audio from the unit, I do use it to stream audio to it. And this works fantastic. I really like the ability to use my phone to stream audio. Been great for listening to web radio. However, it is a little annoying when a phone call comes in, because it will want you to use the unit as a speakerphone, which is an issue since I don't have a mic on this PC.

      The proximity locking feature is also nice. Set it to automatically lock your PC when your phone is out of the specified range (3 settings, Close, Very close, and Intimate) It's nice, but a little too sensitive. I found that if I use my phone to do other tasks it will lock my PC. So I am not using this feature anymore.

      It also says it will allow you to send and receive text messages via the ASUS software. I don't know if this works for anyone, but I have an iPhone 5, and it does not work at all. Not a big deal though, but it is annoying when you have something that doesn't work like it says it would. But this is likely an Apple issue, and not an ASUS issue.

      Overall I am very pleased with this unit and would highly recommend it. I would give it 5 stars, if it didn't try to hijack my phone calls when I am streaming audio to it. The hardware is great, the software needs a little tweaking.

      5.0 out of 5 stars Works good in Linux with some effort
      Reviewed in the United States on February 21, 2024
      Style: Bluetooth 5.0Verified Purchase
      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).

      I tore open the box, plugged it in and it started working in about 10 seconds.

      It is super tiny and you don't even notice it plugged into the USB port.

      This is an instant way to get your computer or laptop the latest Bluetooth 5.0 capability.

      The range is excellent.

      I'm not sure how many BT devices this thing can support at the same time but so far it's performed league better than the integrated BT chip on my budget motherboard. The BT 5.3 is perfect and should be standard just like USB-C.

      Después de comprar más de 5 adaptadores chinos, me decidí a comprar un buen adaptador de marca.
      Este adaptador BT Asus es excelente. La señal es fuerte y de buen alcance, no hay Lag, no hay desconexiones. Lo utilizo para mi control 8bitDo Pro 2 y funciona de maravilla.

      I'm using this on my desktop PC for my Bose QC 35 II and Xbox One controller.

      The Bose have about 100ms of latency or so which is because of the headphones themselves, not usable wirelessly for gaming because of this reason. Fine for anything else, just adjust your audio sync by -0.1s in your video player.

      The controller works very well. Hard to tell, but I think there's about 10ms input lag which is about to same when it's wired. Win win.
