right now I see
/dev/hidraw0,1,2,3

./lsof | grep /dev
(showing bluetooth)

bluetooth 2020   root    0u      CHR                1,3       0t0 2551 
/dev/null
bluetooth 2020   root    1u      CHR                1,3       0t0 2551 
/dev/null
bluetooth 2020   root    2u      CHR                1,3       0t0 2551 
/dev/null
bluetooth 2020   root   14u      CHR              10,62       0t0 3895 
/dev/rfkill
