Bug#787889: general: USB keyboard stops working after a few seconds due to USB suspend

Package: general
Severity: important

Dear Maintainer,

* What led up to the situation?

Upgraded packages on 2015-05-04. Upgrades included kernel update from 3.16.0-4-amd64 to 4.0.0-1-amd64.

* What exactly did you do (or not do) that was effective (or

Attempted to use USB keyboard in, in Xorg and in virtual TTY.

* What was the outcome of this action?

There appeared to be no input from the keyboard. After disconnecting and reconnecting the keyboard it functioned; but after a period of seconds it consistently stopped working until it was disconnected and reconnected again.

* What outcome did you expect instead?

I expected keyboard input to work consistently.

* Is there a workaround?

I am able to work around the issue by overriding USB power management for the keyboard device:

    cat on | sudo tee /sys/bus/usb/devices/3-1.2.2/power/level

Hey hey, i thought it was only me.... keyboard suddenly stopping from time to time (more like every ten minutes).
i think this has to do with either the recent systemd upgrade or the upower upgrades, but it's hard to say.
any i am still using linux-image 3.16.x amd64 so the issue doesn't come from kernel.
