Re: [Trisquel-users] Bluetooth adapter not found

[chris]

The Atheros bluetooth chipset needs a non-free blob. It won't work without  
it. I can conceive of a few explanations for why it may have worked in  
Trisquel. For example it might be if you have booted up another distribution  
or operating system with the non-free firmware that distribution has loaded  
it already. If you reboot it may stay on the chip. If you shut down and then  
start up the system Trisquel won't be able to utilise it. The AR9285 chipset  
(wireless portion) holds the firmware on the chip and no firmware loading is  
required.

We sell USB bluetooth cards to resolve this problem. There is a CSR chipset  
that is compatible with Trisquel and other free software distributions. Not  
all USB adapters with this chipset work though. I'm not 100% certain why.  
This is the case even where the IDs match exactly.
