scsi: introduce a quirk for false cache reporting

2016-09-13T06:08:24+00:00

Some SATA to USB bridges fail to cooperate with some
drives resulting in no cache being present being reported
to the host. That causes the host to skip sending
a command to synchronize caches. That causes data loss
when the drive is powered down.

USB: uas: Add a new NO_REPORT_LUNS quirk

2016-04-13T19:02:28+00:00

Add a new NO_REPORT_LUNS quirk and set it for Seagate drives with
an usb-id of: 0bc2:331a, as these will fail to respond to a
REPORT_LUNS command.

uas: Add US_FL_MAX_SECTORS_240 flag

2015-04-28T10:48:57+00:00

The usb-storage driver sets max_sectors = 240 in its scsi-host template,
for uas we do not want to do that for all devices, but testing has shown
that some devices need it.

This commit adds a US_FL_MAX_SECTORS_240 flag for such devices, and
implements support for it in uas.c, while at it it also adds support
for US_FL_MAX_SECTORS_64 to uas.c.

uas: Add no-report-opcodes quirk

2014-09-24T04:40:48+00:00

Besides the ASM1051 (*) needing sdev->no_report_opcodes = 1, it turns out that
the JMicron JMS567 also needs it to work properly with uas (usb-storage always
sets it). Since some of the scsi devs were not to keen on the idea to
outrightly set sdev->no_report_opcodes = 1 for all uas devices, so add a quirk
for this, and set it for the JMS567.

*) Which has become a non-issue since we've completely blacklisted uas on
the ASM1051 for other reasons

uas: Add a quirk for rejecting ATA_12 and ATA_16 commands

2014-09-24T04:40:48+00:00

And set this quirk for the Seagate Expansion Desk (0bc2:2312), as that one
seems to hang upon receiving an ATA_12 or ATA_16 command.

usb-storage/SCSI: Add broken_fua blacklist flag

2014-07-01T05:47:18+00:00

Some buggy JMicron USB-ATA bridges don't know how to translate the FUA
bit in READs or WRITEs.  This patch adds an entry in unusual_devs.h
and a blacklist flag to tell the sd driver not to use FUA.

uas: Add the posibilty to blacklist uas devices from using the uas driver

2014-03-04T23:38:16+00:00

Once we start supporting uas hardware, and as more and more uas devices
become available, we will likely start seeing broken devices. This patch
prepares for the inevitable need for blacklisting those devices from
using the uas driver (they will use usb-storage instead).

usb-storage: add quirk for mandatory READ_CAPACITY_16

2013-10-16T20:32:04+00:00

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

2012-09-06T00:21:36+00:00

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.
