Bjørn Mork ab4b71644a USB: storage: fix Huawei mode switching regression ... This reverts commit 200e0d99 ("USB: storage: optimize to match the Huawei USB storage devices and support new switch command" and the followup bugfix commit cd060956 ("USB: storage: properly handle the endian issues of idProduct"). The commit effectively added a large number of Huawei devices to the deprecated usb-storage mode switching logic. Many of these devices have been in use and supported by the userspace usb_modeswitch utility for years. Forcing the switching inside the kernel causes a number of regressions as a result of ignoring existing onfigurations, and also completely takes away the ability to configure mode switching per device/system/user. Known regressions caused by this: - Some of the devices support multiple modes, using different switching commands. There are existing configurations taking advantage of this. - There is a real use case for disabling mode switching and instead mounting the exposed storage device. This becomes impossible with switching logic inside the usb-storage driver. - At least on device fail as a result of the usb-storage switching command, becoming completely unswitchable. This is possibly a firmware bug, but still a regression because the device work as expected using usb_modeswitch defaults. In-kernel mode switching was deprecated years ago with the development of the more user friendly userspace alternatives. The existing list of devices in usb-storage was only kept to prevent breaking already working systems. The long term plan is to remove the list, not to add to it.
