Details
My bluetooth mouse only works for a few seconds after the bt
controller initializes. At first, it seems only its "frame
rate" is reduced drastically, then it completely stops
working. It also makes pairing nearly impossible. "hciconfig
hci0 reset" briefly gets the mouse working again.
Firmware revision "0.0 build 95 week 37 2016" from [testing]/linux-firmware 20161205.91ddce4-1 is broken. Firmware revision "0.0 build 30 week 18 2016" from [core]/linux-firmware 20161005.9c71af9-1 works fine. The driver will only print the version if a firmware is already loaded, so after a complete power-off (to clear the firmware) btusb has to be unloaded and reloaded in order to print the version. Kernel is linux-zen 4.8.14-1. Hardware: Intel Wireless 8260 Logitech MX Master |

Bluetooth: hci0: Failed to send Intel_Write_DDC (-22)
Bluetooth: hci0 urb ffff880832248240 failed to resubmit (2)
As well as quite a few repeats of
Bluetooth: hci0 command 0x200c tx timeout
The failed DDC write is interesting, though.
