I'm running Ubuntu 16.04 on Lenovo ThinkPad T470s and quite simply, bluetooth appears to not exist, even though it is clearly in the computer according to all specifications available.
It appears that I'm missing a kernel driver. Sounds easy enough: except I cannot find any information on where to find this driver or even identify which one it is. I've searched online for the specification and all I find is "integrated bluetooth" or something to that effect. The most specific I've found so far is "Intel Unknown" from an Ubuntu page. I have been unable to use this information to find any kind of Linux bluetooth driver, whether from Intel or anywhere else.
lsusb show anything useful but here is the output anyway:

So, quite frankly, I'm stuck, and I haven't been able to find anything useful online. Any tips on how to identify my bluetooth chip and/or find Linux (Ubuntu 16.04) drivers for it?
