Thi= s, in turn, requires CONFIG_SERIAL_DEV_BUS=3Dy, but most desktop distros ship a k= ernel with CONFIG_SERIAL_DEV_BUS=3Dm. Long story short, I was successful in bringing Bluetooth up and running on Venue 8 Pro back in the day, so try compiling a kernel with the configurati= on flags mentioned. No further action should be required -- BlueZ should automatically pick the port up and attach the HCI. --=20 You may reply to this email to add a comment.
