To gcc, I think? Stroller.

I am wondering about the udev conflict... [...] Hmmm, I'm not entirely sure how you must resolve this conflict. Based on the fact that there are no stable versions of dev-libs/libgudev left, I *think* you just need to add the gudev USE flag to sys-fs/udev (which is unset by default), which should then satisfy virtual/libgudev and thus resolve the conflict.

I browsed their udev rules and found some rules pointing in that direction but none specifically matching the PCI ID of my keyboard and the wildcards ... I am not sure. But they seem to do it specifically, yes -> # cat /sys/module/usbcore/parameters/autosuspend 2 # my keyboard # cat /sys/bus/usb/devices/3-1.6/power/control on I assume it won't hurt much if I disable USB autosuspend in general for now? Power savings should be minimal, right? (desktop here, AC etc) Doesn't the powertop utility have a facility to do this per-device and to see what the current power-save settings are per-device? Surely a bit easier to use than directly messing about with udev rules?
