USB Power on standby
Hi all,
I have a problem with USB power management when my system goes into standby (manually, I don't allow automatic standby).
What I want is for the USB devices to be powered down when in standby mode. I have a problem with my USB wifi modem which doesn't seem to like being left in a powered up state when the system is asleep ... when I resume it usually plays up, sometimes necessitating a restart. Also, I like my USB keyboard to be powered down too (so my cat doesn't inadvertently wake the system up if he steps on the keyboard
). I want to be able to resume the system just by pressing the power switch momentarily. My old system running 12.04 worked this way by default (no USB power when sleeping).
The system specs are in my sig below. I thought it was a problem with my motherboard for a while, but I think I've been through all the power settings in the BIOS and it hasn't made any difference.
Any help appreciated.

The goal posts keep moving in Linux all the time ... previous fixes are deprecated and of course, the latest is systemd.
