For example (assuming you have CONFIG_USB_SUSPEND enabled), suppose you do echo off >/sys/bus/usb/devices/.../power/level echo auto >/sys/bus/usb/devices/.../power/level (fill in the ... with the correct pathname for the Huawei device). Afterward does it still work? Does the device's entry in "lsusb -v" change?
