Which Bluetooth dongle is compatible with Linux-libre?
Hi all. I am using a Vikings X200 and used to have working Bluetooth, but some weeks ago the Bluetooth support suddenly disappeared. When looking for USB dongles, I saw that some require firmware and I expect won't work.
Could anybody recommend me a Linux-libre compatible Bluetooth dongle? Many thanks in advance!

Although an explanation for why your existing bluetooth seemed to "suddenly disappear" might be in order.
Thanks, I'll look into that one! I guess I will order a CSR8510 based dongle within the Netherlands.
I haven't really taken any time to look into what happened. I was thinking it could either be a driver issue related to a kernel update or maybe the hardware just stopped working. I don't see it either in `lspci` or `lsusb` which would suggest me that the hardware gave up...
Another option is from Technoethical:

They're based out of Romania if that makes things easier for you.
I ended up getting a LogiLink BT0015. Apparently it has a higher power class than the TP-Link dongles. When I plugged it in, Bluetooth was back immediately!
Many thanks!!
I'm using a UB4A from TP-Link recognized as:
Bus 003 Device 002: ID 0a12:0001 Cambridge Silicon Radio, Ltd Bluetooth Dongle (HCI mode)
Which confirms what's stated on the h-node page:

Yep, I have the same here:
