            Bug ID: 202465
           Summary: Bluetooth adaptor dies - 0489:e0a2 Foxconn / Hon Hai
           Product: Drivers
           Version: 2.5

I have a 2018 Dell XPS 15 9575 2-in-1 laptop (the one with VEGA graphics). The
bluetooth adapter reports as 0489:e0a2 Foxconn / Hon Hai (which is curious,
because all other references to this adapter in kernel.org date back to 2011 or
2012).

The bluetooth adapter works well until it abruptly dies. Often times, the
bluetooth adapter simply dies in the middle of use, but the laptop going to
sleep seems to increase the frequency of these issues.

I've verified that the issue does not exist in kernel 4.14.94-1 (although this
kernel has other compatibility issues with my laptop.

I've verified that using modprobe to remove and readd btusb does not bring the
bluetooth device back, and neither does restarting the systemd service.


I'm using Manjaro Linux 18 (Gnome 3.30.2), Systemd 239.303, and bluez 5.50-6.
