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
  ineffective)?

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

If this is still a problem on the current stable release or in
unstable, please file a new bug with hardware- and USB state details
against the (kernel) device driver; preferably upstream. For now,
nobody seems to be investigating this bug report, and after 5 years
of silence I'm closing it.

Chris
