It's probably worth writing this up for bugs@ (at least include dmesg and lsusb -v). Not sure if anyone will have an idea what to do, but there's a higher chance of it being seen by someone with the right knowledge there than here on misc@. > I am wondering if there is a command with which I can poweroff the > keyboard in /etc/apm/suspend? There isn't. Maybe you could at least sleep until the keyboard is unplugged though? while usbdevs | grep "somestring"; do sleep 1; done
