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

2013-02-28T14:59:07+00:00

commit 18e03310b5caa6d11c1a8c61b982c37047693fba upstream. 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

2013-02-28T14:59:07+00:00

commit cd060956c5e97931c3909e4a808508469c0bb9f6 upstream. 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 Signed-off-by: Greg Kroah-Hartman

USB: storage: optimize to match the Huawei USB storage devices and support new switch command

2013-02-11T16:47:20+00:00

commit 200e0d994d9d1919b28c87f1a5fb99a8e13b8a0f upstream. 1. Optimize the match rules with new macro for Huawei USB storage devices, to avoid to load USB storage driver for the modem interface with Huawei devices. 2. Add to support new switch command for new Huawei USB dongles. Signed-off-by: fangxiaozhi Signed-off-by: Greg Kroah-Hartman

USB: mark uas driver as BROKEN

2012-12-17T18:37:45+00:00

commit fb37ef98015f864d22be223a0e0d93547cd1d4ef upstream. As reported https://bugzilla.kernel.org/show_bug.cgi?id=51031, the UAS driver causes problems and has been asked to be not built into any of the major distributions. To prevent users from running into problems with it, and for distros that were not notified, just mark the whole thing as broken. Acked-by: Sarah Sharp Signed-off-by: Greg Kroah-Hartman

Revert "usb/uas: make sure data urb is gone if we receive status before that"

2012-08-09T15:31:29+00:00

commit c621a81edecdee85da32c566c21836332c764fda upstream. This reverts commit e4d8318a85779b25b880187b1b1c44e797bd7d4b. This patch makes uas.c call usb_unlink_urb on data urbs. The data urbs get freed in the completion callback. This is illegal according to the usb_unlink_urb documentation. This patch also makes the code expect the data completion callback being called before the status completion callback. This isn't guaranteed to be the case, even though the actual data transfer should be finished by the time the status is received. Background: The ehci irq handler for example only know that there are finished transfers, it then has go check the QHs & TDs to see which transfers did actually finish. It has no way to figure in which order the transfers did complete. The xhci driver can call the callbacks in completion order thanks to the event queue. This does nicely explain why the driver is solid on a (usb2) xhci port whereas it goes crazy on ehci in my testing. Signed-off-by: Gerd Hoffmann Signed-off-by: Greg Kroah-Hartman

usb-storage: revert commit afff07e61a52 (Add 090c:1000 to unusal-devs)

2012-07-16T16:04:10+00:00

commit 0070513b5e005161a7a7fd9a3f48f982b41eb094 upstream. This patch (as1560) reverts commit afff07e61a5243e14ee3f0a272a0380cd744a8a3 (usb-storage: Add 090c:1000 to unusal-devs). It is no longer needed, because usb-storage now tells the sd driver to try READ CAPACITY(10) before READ CAPACITY(16) for every USB mass-storage device.

SCSI & usb-storage: add try_rc_10_first flag

2012-07-16T16:04:10+00:00

commit 6a0bdffa0073857870a4ed1b4489762146359eb4 upstream. Several bug reports have been received recently for USB mass-storage devices that don't handle READ CAPACITY(16) commands properly. They report bogus sizes, in some cases becoming unusable as a result. The bugs were triggered by commit 09b6b51b0b6c1b9bb61815baf205e4d74c89ff04 (SCSI & usb-storage: add flags for VPD pages and REPORT LUNS), which caused usb-storage to stop overriding the SCSI level reported by devices. By default, the sd driver will try READ CAPACITY(16) first for any device whose level is above SCSI_SPC_2. It seems likely that any device large enough to require the use of READ CAPACITY(16) (i.e., 2 TB or more) would be able to handle READ CAPACITY(10) commands properly. Indeed, I don't know of any devices that don't handle READ CAPACITY(10) properly. Therefore this patch (as1559) adds a new flag telling the sd driver to try READ CAPACITY(10) before READ CAPACITY(16), and sets this flag for every USB mass-storage device. If a device really is larger than 2 TB, sd will fall back to READ CAPACITY(16) just as it used to. This fixes Bugzilla #43391. Signed-off-by: Alan Stern Acked-by: Hans de Goede CC: "James E.J.
