At last, an adaptor that works.on Linux

Tried 3 adaptors that supposedly work on Linux Mint, but didn't. This adaptor works perfectly on Linux Mint (check blueman is installed and updated & unblock with rfkill, if it doesn't work out of the box). Just what I needed for transferring files from my mobile to the PC.
