Oh... I checked my kernel .config and it still has "CONFIG_USB_SUSPEND
Y" - will this be overridden somewhere else? I had so far no issues with
it so I would very much like to use it. Also checking usbcore entry sais
"2" for autosuspend so I assume I have it still enabled? Then it does
not work anymore...
