Translating, we see that the terms 20 28 here mean what more bus traces
show as x14 x1C.  That again suggests talk-like-Windows might be:

-y "5A 00 08:00:00:00 00 00:1C 00" -i x1C

Those devices that only agree to copy in x14 = 20 bytes may be omitting
the optional 8 byte block descriptor, in accord with what I think I
remember MMC requires, though simultaneously in discord with what I'm
almost sure I remember SBC recommends.

As you probably already know, the page 3F MODE-SENSE request is made only 
to determine whether the device is read-only.  Most USB storage devices 
handle that request okay; there's only a handful that doesn't.  That's why 
we don't disable it by default.

It's not clear to me what is the best way to take care of the devices that 
choke on page 3F.  Should we use a special flag for those devices or 
should we disable it entirely?

Some of us have suggested substituting:

-y "5A 00 08:00:00:00 00 00:1C 00" -i x1C // Mode Sense 10 of SBC/MMC
Page x08 Cacheing for 8 byte header, optional 8 byte block descriptor,
and xC byte standard page x08 length

Lately that suggestion appeared in talk re discovering Win protocol that
paused near:

http://marc.theaimsgroup.com/?l=linux-scsi&m=106427309605764
Subject:  usb storage traces
Date:     2003-09-22 23:25:17

That talk included my claim:

Subject:  Re: [linux-usb-devel] [2.6-test] Bug in usb-storage or scsi?
Date:     2003-09-11 20:42:33

I have some reason to believe Windows often passes thru something like:
-x "1A 00 08 00 18 00" -i x18
i.e. a ModeSense6 of Cacheing page x08 for the whole 4 byte header plus
one whole 8 byte block descriptor plus the whole xC byte standard page.

Pat, I think maybe you're misunderstanding the reason behind this thread.  
The device in question wasn't failing the MODE-SENSE(10) for page x08 
(determine cache-type); it was failing the MODE-SENSE(10) for page x3F 
(where only the first 4 bytes are read to determine write-enable).

The code that does this is in 
drivers/scsi/sd.c:sd_read_write_protect_flag().

That much I knew, thanks for finding the time to nak me.

Great link, thanks.  There now in -test9 I think I see:

We guess writable if need be, but we prefer to settle for:

sdkp->write_prot = ((data.device_specific & 0x80) != 0);

after the first command that works in the sequence:

sd_do_mode_sense(..., 0x3F, ..., 4, ...);
sd_do_mode_sense(..., 0, buffer, 4, ...);
sd_do_mode_sense(..., 0x3F, buffer, 255, ...);

I mean to suggest, ahead of these more creative (i.e. less friendly)
alternatives, in order to fetch that bit of header, we try a command
that more closely resembles the commands of the Talk Like Windows set,
e.g.:

sd_do_mode_sense(..., 0x08, ..., 4, ...);

I'm pleased to think I see sd.c sd_do_mode_sense via scsi_lib.c
__scsi_mode_sense will round up our header-only length of 4 to 8 when
using op x5A MODE_SENSE_10 rather than op x1A MODE_SENSE.

Furthermore, I believe we'd work better still if we fit our first try
completely into the Talk Like Windows command set.  My first glance at
__scsi_mode_sense says we don't reliably produce completely equivalent
op x5A MODE_SENSE_10 vs. op x1A MODE_SENSE.  This behaviour I recognise
from other hosts.

Me, I think the equivalent mode sense near here are:

-y "1A 00:08:00 18 00" -i x18 // x18 = 4 header + 8 block desc + xC page
-y "5A 00 08:00:00:00 00 00:1C 00" -i x1C // x1C = 8 header + ...

But I think if we try:

sd_do_mode_sense(..., 0x08, ..., 0x18, ...);

instead we get the inconsistent pair:

-y "1A 00:08:00 18 00" -i x18
-y "5A 00 08:00:00:00 00 00:18 00" -i x18 // four short of x1C wanted

And I think if we try:

sd_do_mode_sense(..., 0x08, ..., 0x1C, ...);

instead we get the inconsistent pair:

-y "1A 00:08:00 1C 00" -i x1C // four beyond of x18 wanted
-y "5A 00 08:00:00:00 00 00:1C 00" -i x1C

> ...

Am I yet more clear than mud?

There's an excellent reason for _not_ doing this, at least as far as 
usb-storage is concerned.  Namely, many USB Mass Storage devices die when 
they receive MODE-SENSE(10) for page x08 but handle page x3F perfectly 
well.  Ronald's device is a rather unusual exception.

Do these devices die for all lengths of op x5A MODE_SENSE_10 of page
x08, or only for the rude, header-only, 4 or 8 byte length that we get
by default if we patch drivers/scsi/ minimally?

That is, do these devices die only when assaulted by:

sd_do_mode_sense(..., 0x08, ..., 4, ...);

in place of the more Windows-like:

sd_do_mode_sense(..., 0x08, ..., 0x1C, ...); // if x5A MODE_SENSE_10
sd_do_mode_sense(..., 0x08, ..., 0x18, ...); // if x1A MODE_SENSE

?

Patrick,
attached is a file (err_messages.txt) from an attempt to attach my Sony
camera (S70) via usb-storage to my system. 
It should include the relevant errors, if you want me to try something
else let me know. It's the only usb and scsi device on that system, so I
won't be able to kill anything else.
I have also attached a file (succ_messages.txt) after I did:
echo "Sony:Sony DSC:0x4000" > /proc/scsi/device_info
which shows a successful (yeah) attempt to connect the camera to the
system.
If you need anything else, just let me know.
Thanks for your help.
Ronald
BTW: I'm not on either list, if you (list users) have questions, need me
to try something else. Please contact me directly.
PS: Sorry for the cross posting, but maybe we can figure it out this
way.
