It isn't integrated to other system with linux kernel, such as Android, Chrome OS, etc. On these system, how can we switch the device? Then those systems will have to add modeswitch. If we are to do mode switching in kernel space, there has to be an additional technical benefit over the existing and well working solution in user space. > 2. usb_modeswitch often sends the Windows switching command to switch Huawei device, but not sends Linux switching command. This maybe causes some unexpected problem. You have two commands? What is the difference? Anyway, if usb_modeswitch has issues, these problems need to be fixed. Independent from that, there is a problem with user space mode switching. Namely it doesn't work with reset_resume(). Thus we cannot do sane S4 with the user space solution. However, the problem cannot be solved by merely by adding the switch to the storage driver.
