Do you know what the chipset is?
If it is a USB adapter run:
lsusb
If it is built-in run:
lspci
Look for a line that reads something about bluetooth... and post it here.
For the USB adapters at least some CSR chipsets are supported in Trisquel.
Keep in mind there is a huge difference in quality of the the adapters. The
only ones which work reliably are more expensive adapters with some of the
CSR chipsets.
I want to say there is another free software friendly bluetooth chipset, but
for the life of me I can't remember what it is.
