```
We were able to successfully enable our BT device in the system after boot up, 
which points to something in system boot/power sequence preventing BT from 
enabling.

The RTK 3rd party module exhibited the same behavior as our Intel
module, which points to a system level setting that doesn’t allow for
any device to be used other than what ships with the platform (Qualcomm
card) – thought to be likely due to BIOS or Linux Kernel rule setting.

We checked with Lenovo as they used to have a BIOS setting that wouldn’t
allow another adapter to work (called mutual authentication), but this
was removed a few years ago.

Unfortunately we cannot debug any further on this as we do not have access to 
the proprietary code needed to do further debug. Our best recommendation is to 
take the engineering debug analysis we have been able to provide above and 
contact Lenovo to determine if they will conduct further testing to determine 
the boot/power up setting that is preventing the BT from being enabled.
