But that doesn't sound correct to me. In some cases, pci_enable_device() is hooked by the architecture to effectively turn on the device, ie, enable clocks or power, etc... I've seen embedded stuff like that and some PowerMac devices do that too (though not those USB ones in that specific case). I think nothing should happen before pci_enable_device() Ben. _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
