Second brand I've tried. This one really works with Linux. Hooray.

Nice device

Received the Panda Bluetooth Adapter in good packing condition. The Bluetooth Adapter was detected automatically by the Ubuntu 20.04 OS and started working with out any manual settings. Able to pair with my headphones with out any trouble. Satisfied with this Panda Bluetooth Adapter.

Haven’t tried linux yet but plug and play immediately under Windows 10. Manufacturer provides excellent support. Quick in responding.

I bought this Panda bluetooth adapter to use on my Windows 7 64-bit laptop, which is 5 years old and doesn't have built-in bluetooth. I had previously tried to get a different brand of adapter to work on this laptop without success.I initially had trouble with the Panda adapter too, but I've finally gotten it to work. I'm giving it 5 stars as it does now work, and because the Panda Wireless customer support is quite good. They were quick to respond to my emails, even late at night and on the weekend. The below information is for anyone who might encounter the same problem I did.The adapter came with a CD which installs "CSR Harmony" drivers. Customer support no longer recommends you install this. Most of my problems would have been avoided if I had ignored the CD and simply let Windows download and install the default drivers. However, I did install from the CD. The adapter worked at first - I was able to connect a Bose bluetooth speaker and play music. After unplugging the adapter and plugging it back in though, it didn't work again. The bluetooth icon didn't display in the notification area, and when I opened Bluetooth Devices from the Control Panel, none of the buttons on that page worked.I eventually uninstalled the CSR Harmony software. After doing that, the adapter itself seemed to be ok - I was able to successfully use it together with a bluetooth mouse. But I still couldn't get my bluetooth speaker to work again. I alternately got error messages that the drivers for the speaker couldn't be found, or that they were not successfully installed.In Device Manager, the entry for the speaker was labeled "Bluetooth Peripheral Device", and it showed a yellow exclamation mark. The "Properties" window indicated "This device is not configured correctly. (Code 1) The name is already in use as either a service name or a service display name." This error was what was causing the driver install to fail, and it seems to have been due to registry entries (under HKEY_LOCAL_MACHINESYSTEMCurrentControlSetservices) that weren't appropriately removed when the CSR Harmony software was uninstalled. The entries all started with "csr" (csr_a2dp, csr_bthav, csravrcp, CsrBtPort, csrpan, csrserial, csrusb). The corresponding csr*.sys files did not exist in my "C:WindowsSystem32drivers" folder. So I exported those keys (for backup, to be on the safe side), and then deleted them. (Important note: Do not edit your registry like I did, unless you know what you are doing; otherwise you may cause serious damage to your system.)After deleting those registry keys, the device driver install for the speaker still failed, and I almost gave up hope. But after rebooting the computer the next day, I tried again, and the problem was gone! (So it seems that both the registry fix and the reboot were required). Device Manager no longer showed the yellow exclamation mark. I removed the speaker from my Bluetooth list, added it back again, and then it worked. It also still works, after unplugging the adapter and plugging it back in.
