Hi Josua, I agreed your pointer, and making a module parameter is better than default switching function. I'm feeling sorry not to study usb storage driver well. And I'll figure out how to make it working on H21. Anyway, thanks for your advice.

I'm not comfortable with the approach of taking away the user choice completely and make it impossible to test userspace programs with the device. I'd rather like to have a module parameter like in "option_ms" or "sierra_ms" which makes it possible to skip the switching function. You can still make it the default to switch the device.
