USB: storage: fix Huawei mode switching regression

2013-03-07T04:23:17Z

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.

USB: usb-storage: unusual_devs update for Super TOP SATA bridge

2013-02-14T17:22:02Z

The current entry in unusual_cypress.h for the Super TOP SATA bridge devices seems to be causing corruption on newer revisions of this device. This has been reported in Arch Linux and Fedora. The original patch was tested on devices with bcdDevice of 1.60, whereas the newer devices report bcdDevice as 2.20. Limit the UNUSUAL_DEV entry to devices less than 2.20. This fixes https://bugzilla.redhat.com/show_bug.cgi?id=909591 The Arch Forum post on this is here: https://bbs.archlinux.org/viewtopic.php?id=152011 Reported-by: Carsten S. Tested-by: Carsten S.

USB: storage: properly handle the endian issues of idProduct

2013-02-08T20:15:25Z

1. The idProduct is little endian, so make sure its value to be compatible with the current CPU. Make no break on big endian processors. Signed-off-by: fangxiaozhi Cc: stable Signed-off-by: Greg Kroah-Hartman

usb-uas: set max_lun and max_channel

256 luns is what the sam-4 address method 0 can handle and what the qemu uas emulation supports. So pick that for now. [ v2: unlike the other two max_* fields max_channel isn't max+1 ] Signed-off-by: Gerd Hoffmann Signed-off-by: Greg Kroah-Hartman

USB: storage: avoid scanning other targets for single target device

2013-01-21T00:12:53Z

This patch sets scsi_host->max_id as 1 if the device's quirk flag of US_FL_SCM_MULT_TARG isn't set, because there are only 6 mass storage devices marked as mutiple targets from unusual_devs.h. This patch is a small optimization about scanning targets, and avoid scanning other 7 non-existed targets for single target device.
