With the Linux kernel, USB power savings are also annoying on Logitech devices. If you set everything on USB bus to powersave, their mice and keyboards will go to sleep every few seconds unless there's continuous activity. I have experience with Dell and Apple keyboards on Linux, and they don't suffer from this issue. The problem is not terrible, but requires a special udev rule to exclude them from powersaving, which is annoying.
