[PATCH] USB Storage: Force starget->scsi_level in usb-storage scsiglue.c

2005-12-21T22:46:34+00:00

When the usb-storage module forces sdev->scsi_level to SCSI_2, it should
also force starget->scsi_level to the same value.  Otherwise, the SCSI
layer may attempt to issue SCSI-3 commands to the device, such as REPORT
LUNS, which it cannot handle.  This can prevent the device from working
with Linux.

The AMS Venus DS3 DS2316SU2S SATA-to-SATA+USB enclosure, based on the
Oxford Semiconductor OXU921S chip, requires this patch to function
correctly on Linux.  The enclosure reports a SCSI-3 SPC-2 command set
level, but does not correctly handle the REPORT LUNS SCSI command -
probably due to a bug in its firmware.

It seems likely that other USB storage enclosures with similar bugs will
also benefit from this patch.

Tony Lindgren  collaborated in the development of this
patch.

Thanks for the pointer, and yes, it is harmless, but it floods the
console with the messages which hides other (potentially important)
messages...following your example I've made a patch which fixes the
problem.

[PATCH] USB: Maxtor OneTouch button support for older drives

2005-11-17T19:29:54+00:00

This small patch adds a device ID used by older Maxtor OneTouch drives
(the ones with blue face-plate instead of the fancy silver one used in
newer models). The button on those drives works well with the current
driver.

[PATCH] usb-storage: Fix detection of kodak flash readers in shuttle_usbat driver

2005-11-17T19:29:54+00:00

Peter Favrholdt reported that his Kodak flash device was getting
detected as a CDROM, and he helped me track this down to the fact that
the device takes a long time (approx 440ms!) to reset.

This patch increases the delay to 500ms, which solves the problem.

[PATCH] USB: onetouch doesn't suspend yet

2005-11-17T19:29:54+00:00

The onetouch support doesn't suspend correctly (leaves an interrupt
URB posted, instead of unlinking it) so for now just disable it
when PM is in the air.

I actually have this device, and kernel reports blacklist entry is no

[PATCH] USB Storage: Expand range of Freecom unusual_devs entry

2005-10-28T23:47:50+00:00

Freecom seems to be one of those vendors that can't get the GET CAPACITY
thing right. This expands the US_FL_FIX_CAPACITY flag for the entire
range of their fccd product line.

This is based on a patch sent by Stuart Black
.

[PATCH] PATCH: usb-storage: use kthread API

2005-10-28T23:47:50+00:00

This patch is originally from Alan Stern (as569).  It has been rediffed
against a current tree.

This patch converts usb-storage to use the kthread API for creating its
control and scanning threads.  The new code doesn't use kthread_stop
because the threads need (or will need in the future) to exit
asynchronously.

[PATCH] PATCH: usb-storage: implement minimal PM

2005-10-28T23:47:50+00:00

This patch from Alan Stern started as as568.  It has been rediffed against
a current tree.

This patch adds minimal suspend/resume support to usb-storage.  Just enough
for it to qualify as PM-aware.

[PATCH] PATCH: usb-storage: allocate separate sense buffer

2005-10-28T23:47:50+00:00

This patch is from Alan Stern (as560).  It has been rediffed against a
current tree.

This patch allocates a separate buffer for usb-storage to use when
auto-sensing.  Up to now we have been using the sense buffer embedded in a
scsi_cmnd struct, which is dangerous on hosts that (a) don't do
cache-coherent DMA or (b) have DMA alignment restrictions.
