Hello, I have no idea where to start debugging this. But USB hotplug does not seem to work at all in linux-next if autosuspend is enabled. I am running next-20120723 with this: nemi:/tmp# grep . /sys/bus/usb/devices/usb*/power/control /sys/bus/usb/devices/usb1/power/control:auto /sys/bus/usb/devices/usb2/power/control:auto /sys/bus/usb/devices/usb3/power/control:auto /sys/bus/usb/devices/usb4/power/control:auto /sys/bus/usb/devices/usb5/power/control:auto /sys/bus/usb/devices/usb6/power/control:auto /sys/bus/usb/devices/usb7/power/control:auto /sys/bus/usb/devices/usb8/power/control:auto Connecting a device to any port, whether it is external or internal (using rfkill to "connect") has no effect. Nothing in the log. No uevent. Setting control to "on" on a port will reenable hotplug on that port. Any device connected while in "auto" state will suddenly be discovered.
