People sometimes create their own custom-configured kernels and forget to enable CONFIG_SCSI_MULTI_LUN. This causes problems when they plug in a USB storage device (such as a card reader) with more than one LUN. Fortunately, we can tell fairly easily when a storage device claims to have more than one LUN. When that happens, this patch asks the SCSI layer to probe all the LUNs automatically, regardless of the config setting. The patch also updates the Kconfig help text for usb-storage, explaining that CONFIG_SCSI_MULTI_LUN may be necessary.

The Cypress ATACB unusual-devs entry for the Super Top SATA bridge causes problems. Although it was originally reported only for bcdDevice = 0x160, its range was much larger. This resulted in a bug report for bcdDevice 0x220, so the range was capped at 0x219. Now Milan reports errors with bcdDevice 0x150. Therefore this patch restricts the range to just 0x160.

The USB storage operation of Nokia Asha 502 Dual SIM smartphone running Asha Platform 1.1.1 is unreliable in respect of data consistency (i.e. transfered files are corrupted). A similar issue is described here: http://discussions.nokia.com/t5/Asha-and-other-Nokia-Series-30/Nokia-301-USB-transfers-and-corrupted-files/td-p/1974170 The workaround is (MAX_SECTORS_64): rmmod usb_storage && modprobe usb_storage quirks=0421:06aa:m The patch adds the tested device to the unusual list permanently.

Many cards based on CY7C68300A/B/C use the USB ID 04b4:6830 but only the B and C variants (EZ-USB AT2LP) support the ATA Command Block functionality, according to the data sheets. The A variant (EZ-USB AT2) locks up if ATACB is attempted, until a typical 30 seconds timeout runs out and a USB reset is performed. https://bugs.launchpad.net/bugs/428469 It seems that one way to spot a CY7C68300A (at least where the card manufacturer left Cypress' EEPROM default vaules, against Cypress' recommendations) is to look at the USB string descriptor indices. A http://media.digikey.com/pdf/Data%20Sheets/Cypress%20PDFs/CY7C68300A.pdf B http://www.farnell.com/datasheets/43456.pdf C http://www.cypress.com/?rID=14189 Note that a CY7C68300B/C chip appears as CY7C68300A if it is running in Backward Compatibility Mode, and if ATACB would be supported in this case there is anyway no way to tell which chip it really is. For 5 years my external USB drive has been locking up for half a minute when plugged in and ata_id is run by udev, or anytime hdparm or similar is run on it. Finally looking at the /correct/ datasheet I think I found the reason. I am aware the quirk in this patch is a bit hacky, but the hardware manufacturers haven't made it easy for us.

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.

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.
