Subject: [PATCH] Add a new 04ca:3015 QCA_ROME device
Date: Mon, 28 Aug 2017 18:09:39 +0300	[thread overview]
Message-ID: <86a45247-6443-6bc3-285d-b8191575ef1c@gmail.com> (raw)

This patch adds the 04ca:3015 (from a QCA9377 board) Bluetooth device to 
the btusb blacklist and makes the kernel use the btqca module instead of 
btusb. The patch is necessary because, without it the 04ca:3015 device 
defaults to using the btusb driver, which makes the WIFI side of the 
QCA9377 board unusable (obtains 0 MBps in speedtest, when the 04ca:3015 
bluetooth is used with an audio headset).
