MANUFACTURER ANSWER: Yes, but can vary with Linux distro. With latest version of Raspian, you should be fine. We have details here: http://plugable.com/2013/12/10/using-the-plugable-usb-bt4le-bluetooth-adapter-with-the-raspberry-pi Thanks for asking!
I have it running on my raspberry pi and followed the directions and am unable to connect. The device will not pair. I am trying to pair with a passcode.
I have a Raspberry Pi B and will not work. It always comes back as "Fail" if I check the status via command lines and will not even turn on with I force it to via commands. I returned it promptly.
