And looks like the trigger to mdm6600 to enter low power states is done via USB: # echo auto > /sys/devices/platform/44000000.ocp/4a064000.usbhshost/4a064800.ohci/usb1/1-1/power/level Looks like with that and modem enabled I'm seeing 207mW power consumption on a and idle system with screen off on my power supply. Opening /dev/ttyUSB4 makes the power consumption go up to 502mW.. So now we need the wakeirqs and PM runtime to work for ohci and then the device can be used for few hours on batteries.
