Title:
Bluetooth: "device descriptor read/64, error -110" on cold boot
Status in linux package in Ubuntu:
Confirmed
Bug description:
Every time when I turn on my laptop using Power button I always get a
long pause at bootup. I experience this behavior about half of year or
so I think (with 14 LTS I had no pause at bootups).
I analyzed dmesg output (full printout is attached) and found that cause for
this pause is integrated bluetooth (notice pause ends at 23 second):
$ dmesg|grep "usb 1-1.1"
[ 1.973231] usb 1-1.1: new full-speed USB device number 3 using ehci-pci

In fully booted system bluetooth is working without problems.
Later restarts don't produce mentioned pause and dmesg doesn't show
mentioned errors.
