Also I think this problem is distribution-independent, that's why i'm asking here uname -a

There are many similar questions to mine on this site but all i've seen are based on the missing firmware file. So it seems like the device does not require a firmware to be uploaded on boot like many other broadcom devices but it still does not work.ĭoes anyone has experience with broadcom devices and can help me troubleshoot the problem? Google shows that problems with broadcom devices are common and the usual solution is to extract a proprietary firmware file from the windows driver ( AskUbuntu, Arch Wiki) but in my case the driver does not specify a firmware file in the *.inf file. I'm trying to get a Broadcom Bluetooth Adapter working on Ubuntu/Linux.
