I'm using Gigabyte GA-H55S2H motherboard. Is there any option to disable the USB Power when the PC is turned off or put into hibernation. It is giving me trouble as I need to turn on my USB powered broadband modem for several period only and not always on. I am sure other users who want to schedule their broadband connection to resume from hibernation for periodic download would want the same feature to be available.

USB is part of the acpi power specification but you may or may not have it enabled in bios and with software. It may not be part of your bios or boards design. You'd have to look that up.

Can I assume you mean that your power goes off and you want it to stay on? If so you may be forced to use a powered hub to keep the modem alive. It still may be that the drivers are faulty and won't resume.

Check bios settings first for any advanced power features and then to the OS for power settings.

The USB power is always on even if the PC is turned off or in standby/hibernation.
