------ commit 200e0d99 and commit cd060956, only put the switch command into kernel, instead of userspace usb_modeswitch utility.
------ Because in the embedded linux system, Android, or Chrome OS, etc. They don't integrate userspace usb_modeswitch utility for switching.
----- In commit 200e0d99, we send the Linux switching command to Huawei devices, so on PC Linux, you can get the largest capacity of Huawei device, including the CDROM feature. So I think this solution can meet the user's requirement in Linux.

-------But in this multiple modes, there is only one is for Linux. We don't advice the user to use the other mode not for Linux. It may cause some unexpected problem.

----In commit 200e0d99, the switching command will ask Huawei device to offer the CDROM(and /or SD) port together. After switching, users also can get the mounting storage device.

------ In our opinions, it is better to switch Huawei device in kernel.
------ usb_modeswitch is a tool for Linux.
------ We can not guarantee it will be integrated in all the system which integrates linux kernel. But linux kernel itself can.
