Ubuntu 18.04 running bluez 5.37-0ubuntu5.1 has fixed the 16.04 problem
of bluetooth not running after a suspend. My mouse has successfully
reconnected 100+ times. The USB inputxx is still incrementing at each
resume, so that may not have been related to the problem.

Seeing very similar symptoms on Ubuntu 17.10 running 4.13.0-19-generic or
4.14.0-041400-generic.
Sometimes, but not every time, BT is not available after resuming from suspend.
>From other data sources, the root cause is a lack of .reset_resume
handler in the BT driver.
A possible interim fix
The bluetooth failure to resume after a suspend seems USB related. The failure
happens
about 50% of the time, and when it does, disabling bluetooth and restarting
fixes
it.

It seems the problem for me is the action of 'turn off' bluetooth.
I dual boot with Windows 10. If I chose to 'reboot' (not shutdown) from
windows and boot into ubuntu, bluetooth will start properly and working
fine. The moment I turned off bluetooth it stop working, even reboot
again.

I have to add that in my case, 16,6% to 20% of the times (1 out of 5 or
6 times) the bluetooth is working after recovering from sleep mode,
since the update.
Before the update, it was 1% of the time -I don't have real statistics,
the idea is that it barely ever happened.
Weird.
