Can't get this to work. No matter what

[linuxy9]

I have updated my kernal and a new install of Linux Mint to once was a intel atom skylake tablet. Everything was okay until i need a mouse and keyboard witch i havr bu the bluetooth does not work. I must tell you I am a noob at this most definitely.

What ive tried doing

• Compled the Drivers
• Wifi works

• bluetooth servive does not start even with hciattach

This is a reltek bluetooth and wifi device

Cant remember the name of it rn since my tablet is wall charging.

I desperately need help and this newest kernal.

What kernel version are you running? With something as new as 4.15+, the BT driver is there and it will work IF the firmware is available. Look in the dmesg output for clues.
