## Questions & Answers

**Q: Will this device mow my grass?**
A: While it may mow the grass what I'd really like for it to do is give a strong, consistent signal.  To identify the specific item it is pairing to and not just to phone 1, phone 2, etc.  To make pairing to my computer easy so one doesn't have to go to the control panel every time and turn off this or that in order to use the headset.  Does it do any of that???

**Q: does this work on linux**
A: This was a little tricky but not too bad.. you have to get a file and you may have to modify the last part like i did had to
First i install blueman via sudo apt-get install blueman
sudo wget https://s3.amazonaws.com/plugable/bin/fw-0a5c_21e8.hcd -O /lib/firmware/brcm/BCM20702A0-0a5c-21e8.hcd
sudo wget https://s3.amazonaws.com/plugable/bin/fw-0a5c_21e8.hcd -O /lib/firmware/fw-0a5c_21e8.hcd
sudo modprobe -r btusb
Still was not working...so i ran command dmesg in terminal and looked at the failure message . It was very close but mine said it could not find BCM20702A1-0a5c-21e8.hcd (notice the top A0-0a5c-21e8.hcd) so i ran a symbolic link to fw-0a5c_21e8.hcd.

sudo ln -s /lib/firmware/fw-0a5c_21e8.hcd /lib/firmware/brcm/BCM20702A1-0a5c-21e8.hcd
After this i was able to get the bluetooth manager to add the new bluetooth speaker

**Q: How many devices can it support at a time? Can I send/receive files via bluetooth while using my bluetooth mouse using the same bluetooth adapter?**
A: Dear Raymond, Thank you for your questions regarding our BTD-400 Bluetooth Adapter. The BTD-400 can be connected to any number of devices. In your specific set up, you should be able to send/receive files and use your mouse as the profiles use by each device within Bluetooth are different.Please contact us at support@kinivo.com if you have any additional questions.

**Q: Can I use this dongle to link to a bluetooth headset, for music? Here is the product I'm thinking of http://www.amazon.com/LG-Electronics-HBS-700W-Wir**
A: I use this dongle on my computer with an LG 730 bluetooth headset and it works great on music, videos and streaming Netflix. Ive not had an issue with playing anything.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great product! Highly recommended :-D
*by R***N on February 16, 2015*

I have been through several similar products and had a LOT of issues with those. You might say that I'm fairly tech savvy (I'm a C++/Java programmer, have setup/customized/maintained MANY Windows and Linux PCs, and have done driver troubleshooting before). Anyway, tried to resolve my issues on the other dongles but the problems I was having appeared to be from the drivers. *THIS PRODUCT* (Kinivo) worked pretty much out of the box (technically I installed from CD first and then from the web), on the first try, and I didn't have to do any deep dive troubleshooting. Had my headset working perfectly within minutes of the install! :-DFor my setup, I have full tower pc behind a plasma tv and am mostly using this to pair with a really cheap wireless headset (for chatting while gaming). It is working perfectly with the Kinivo (great sound, great signal, relatively painless setup). Decently fast shipping. Can't think of any cons.In case, you are trying to decide between other products; here is some more info for reference:1. Note: I will be using the smile.amazon.com links (proceeds towards non-profits of your choice). If you don't want to do that, just replace them with www.amazon.com.2. My (admittedly cheap) BT headset is an "eForCity® Silver Bluetooth Headset". Amazon page - eForCity® Silver Bluetooth Headset3. The first BT dongle that I tried (unsuccessfully) and had problems with was a SANOXY USB. IIRC, this was just using the basic Windows bluetooth drivers. Maybe it would have worked fine with a higher end headset... but since I was able to connect headset-to-phone without any sound issues, I'm blaming the drivers on the dongle. Amazon page - SANOXY® USB Bluetooth Wireless Adapter for HP, Gateway, eMachine, Dell or ANY Laptop/PC Running Windows 98, 98SE, ME, 200, XP, Vista & WINDOWS 74. The second BT dongle I had tried was the SoundBot SB340. This one had some CSR brand drivers but I also had a lot of problems getting my generic device to work correctly / not have horribly sound quality. Amazon page - SoundBot® SB340 Bluetooth 4.0 USB Adapter Universal Plug and Play Dongle Class 2 Transmitter (Newest Bluetooth Version Available) Ready Adapter w/ 3Mbps Data Transfer Rate and 10 meters Range, Compatible w/ Windows WIN8 WIN7 Vista 2003 XP 2000 Me 32/64 ...5. I think I could connect and pair under both of the previous options, but I had a lot of problems with sound quality, particularly with white noise. No such problems with the Kinivo (I've already used it on Steam voice chat and my brother reported that I was coming in loud and clear). For the first 2 dongles, I had originally tried from my USB3.0 port which I later discovered USB3.0 can can interference problems with any wireless devices that use the 2.4GHz spectrum. I did try from my USB2.0 port as well, but no luck there either. The only major change since the first 2 is that I replaced my old 2', non-powered USB2 hub with a 6', powered USB2.0 so that it gets out from behind the TV better. This probably helps, but I believe my white noise problems on the other dongles were driver issues as I had also tested with the TV moved out of the way and clear LOS between the headset and the old dongles (and maybe 4-5' away) .If it works this well for my el cheapo headset, I imagine that you would get even better results with higher end headsets.disclaimer:I am by no means an audiophile. I probably have a slight hearing problem (too much loud music lol). But I'm not deaf either and I am basing this not only off feedback via a recording app but also live chats with someone at the other end. Hope that helps!

### ⭐⭐⭐⭐⭐ Perfect
*by C***O on September 5, 2025*

I’ve been using the Kinivo USB Bluetooth Adapter for my PC, and I’m very impressed with its performance. Setup was quick and hassle-free — just plug it in and the drivers install automatically. Within minutes, I was able to connect my wireless headphones, phone, and even a Bluetooth controller without any issues

### ⭐⭐⭐⭐⭐ Easy to use and Linux-compatible
*by J***. on September 13, 2025*

I plugged this receiver into the back of a Linux box I was using to run my home automation server. It functions great and everything picks it up without even having to install any extra packages or drivers. Very much plug ‘n’ play.
