usb-storage: add quirk for mandatory READ_CAPACITY_16

2013-11-13T03:05:29Z

commit 32c37fc30c52508711ea6a108cfd5855b8a07176 upstream. Some USB drive enclosures do not correctly report an overflow condition if they hold a drive with a capacity over 2TB and are confronted with a READ_CAPACITY_10. They answer with their capacity modulo 2TB. The generic layer cannot cope with that. It must be told to use READ_CAPACITY_16 from the beginning.

usb: remove libusual

2012-09-06T00:21:36Z

The "Low Performance USB Block driver" has been removed which a user of libusual. Now we have only the usb-storage driver as the only driver in tree. This makes libusual needless. This patch removes libusal, fixes up all users. The usual-table is now linked into usb-storage. usb_usual.h remains in public include directory because some staging users seem to need it.

usb-storage: redo incorrect reads

2011-06-07T16:05:42Z

Some USB mass-storage devices have bugs that cause them not to handle the first READ(10) command they receive correctly. The Corsair Padlock v2 returns completely bogus data for its first read (possibly it returns the data in encrypted form even though the device is supposed to be unlocked). The Feiya SD/SDHC card reader fails to complete the first READ(10) command after it is plugged in or after a new card is inserted, returning a status code that indicates it thinks the command was invalid, which prevents the kernel from retrying the read. Since the first read of a new device or a new medium is for the partition sector, the kernel is unable to retrieve the device's partition table. Users have to manually issue an "hdparm -z" or "blockdev --rereadpt" command before they can access the device. This patch (as1470) works around the problem. It adds a new quirk flag, US_FL_INVALID_READ10, indicating that the first READ(10) should always be retried immediately, as should any failing READ(10) commands (provided the preceding READ(10) command succeeded, to avoid getting stuck in a loop). The patch also adds appropriate unusual_devs entries containing the new flag.

usb-storage: add new no_read_capacity_16 quirk

2010-10-22T17:22:05Z

Some Rockbox based mp4 players will crash when ever they see a read_capacity_16 scsi command. So add a new US_FL which tells the scsi sd driver to not issue any read_capacity_16 scsi commands.

usb-storage: add new no_read_disc_info quirk

2010-10-22T17:22:04Z

Appotech ax3003 (the larger brother of the ax203) based devices are even more buggy then the ax203. They will go of into lala land when ever they see a READ_DISC_INFO scsi command. So add a new US_FL which tells the scsi sr driver to not issue any READ_DISC_INFO scsi commands.

USB: Move USB Storage definitions to their own header file

2010-10-22T17:21:50Z

The libusual header file is hard to use from code that isn't part of libusual. As the comment suggests, these definitions are moved to their own header file, paralleling other USB classes.

USB: usb-storage: add BAD_SENSE flag

2009-12-11T19:55:26Z

This patch (as1311) fixes a problem in usb-storage: Some devices are pretty broken when it comes to reporting sense data. The information they send back indicates that they have more than 18 bytes of sense data available, but when the system asks for more than 18 they fail or hang. The symptom is that probing fails with multiple resets. The patch adds a new BAD_SENSE flag to indicate that usb-storage should never ask for more than 18 bytes of sense data. The flag can be set in an unusual_devs entry or via the "quirks=" module parameter, and it is set automatically whenever a REQUEST SENSE command for more than 18 bytes fails or times out. An unusual_devs entry is added for the Agfa photo frame, which uses a Prolific chip having this bug. Signed-off-by: Alan Stern Tested-by: Daniel Kukula Cc: stable Signed-off-by: Greg Kroah-Hartman

usb-storage: prepare for subdriver separation

2009-03-24T23:20:34Z

This patch (as1206) is the first step in converting usb-storage's subdrivers into separate modules. It makes the following large-scale changes: Remove a bunch of unnecessary #ifdef's from usb_usual.h. Not truly necessary, but it does clean things up. Move the USB device-ID table (which is duplicated between libusual and usb-storage) into its own source file, usual-tables.c, and arrange for this to be linked with either libusual or usb-storage according to whether USB_LIBUSUAL is configured. Add to usual-tables.c a new usb_usual_ignore_device() function to detect whether a particular device needs to be managed by a subdriver and not by the standard handlers in usb-storage. Export a whole bunch of functions in usb-storage, renaming some of them because their names don't already begin with "usb_stor_". These functions will be needed by the new subdriver modules. Split usb-storage's probe routine into two functions. The subdrivers will call the probe1 routine, then fill in their transport and protocol settings, and then call the probe2 routine. Take the default cases and error checking out of get_transport() and get_protocol(), which run during probe1, and instead put a check for invalid transport or protocol values into the probe2 function. Add a new probe routine to be used for standard devices, i.e., those that don't need a subdriver. This new routine checks whether the device should be ignored (because it should be handled by ub or by a subdriver), and if not, calls the probe1 and probe2 functions.
