GSM modem should be online. Well I think it's the USB only you have blocking deeper idle states. Are you sure you rmmod:ed all the USB related modules like in my test script? MUSB currently has an unresolved issue where it blocks idle states if loaded. > Are you booting over USB from NOLO? I'm booting over smc91x using u-boot. Regards, Tony
