Hi there ,
I am trying to bring up a BT (HCI interface) module connected to a qualcomm chipset
Trying to bring up the interface using hciconfig but it fails with error no.99 .
Note : ttyUSB here is a cp210x (USB-UART bridge) connected via HSIC
Below are the logs

Below are the Details of the Chipset

Please Let me know a possible solution to overcome this .
