Description nissarin 2006-02-15 14:18:17 UTC
Distribution: 
  Slackware 10.1/10.2/current, Slamd64 10.2/current, SLAX 5.0.6

Hardware Environment:
  1. Gigabyte K8NF-9 Ultra; Athlon64 3000
  2. MSI K7T266 Pro2; Athlon XP 1700+
  3. Some Intel based board w/ Pentium 4 (my friend computer ;) )

Very short description - inserting pendrive into usb port ends with some errors,
restarting hotplug scripts barely resolves problem - I can access pendrive but
only read-only. 
I tried different kernels (with several configurations) - including 2.6.12.x,
2.6.14.7, 2.6.15.3 and 2.6.16-rc2 (all logs are from last one), testing on
different hardware. At the end I checked that pendrive on my friend's WinXP -
works... in fact at the very beging of my 'experiments' I managed to access it
in rw mode - unfortunatelly I have no idea how to reproduce it.
One more thing - pendrive's second device (?) is visible only in certain kernel
configuration (compiled with SCSI_MULTI_LUN I suppose...).

Some logs...

Comment 4 Matthew Dharm 2006-02-15 16:43:59 UTC
You need to configure syslogd to send kern.debug messages to a specific file. 
The USB storage debug messages are lost otherwise.  In /etc/syslog.conf, add
   kern.=debug   /var/log/kernel

That will put the debug messages into the file /var/log/kernel.

Also, is this device supposed to report 2 LUNs?  One about 512MB and the other
about 2MB...

manual

Here is one of manuals shipped with pendrive
(http://pentagram.pl/produkty_new/szczegoly.php?id_grupy=31&grupa=pentagram_pendrive&id_produktu=7&lang=en),
descibing using one of it's features (which actualy could cause this problems),
this model has also other functions and their manuals says that to work they
need "Phison's hardware solutions" so this is probably real manufacturer of
this product.

About those LUNs - probably yes (unfortunatelly I'm not familar with SCSI
'terminology"), there should be 2 "disks", from what I know - first one is
"protected", second is "public" (whole device size is splitted between those
two in specified ratio). Also, I tried today (one my cousin's PC running WinXP)
remove that protected partition but it's minimal size is 1MB. 

Good news (or bad ;)) is that Win2k have similar problems - I can't access it
if I plug in when os is running but if I insert it before system starts, I can
access first device ("protected" one) - read-only. However it was fresh Win2k
install (on my old PC), maybe SP3/4 would fix it. 

If you wish I will send you program which is described in attachment.

I didn't checked ub so far.
Comment 7 Matthew Dharm 2006-02-16 11:08:12 UTC
I'm still not seeing the right debug messages in your log.  Are you sure you
rebuild and reloaded the new version of the module?

If the device is having problems under Windows, then I am suspicious that the
device is bad.  I definately would like to know if SP3/4 fixes that.

Based on what I can see, the device is, actually, reporting that it's read-only.
 It's not a communication error; the device is responding correctly but with an
indication that it is read-only.

The verbose debug log will be truly telling.

Matt, any thoughts?
Comment 10 Matthew Dharm 2006-03-06 11:52:04 UTC
This is definately strange.

The fact that SP3/4 fixes things makes me believe that the device is, simply,
reporting bogus information when asked for write-protect status.  I'm guessing
SP3/4 just ignores the request.

It might be useful to get Alan Stern involved with this -- get the
file-storage-gadget attached to an SP1 and SP4 system and look for a command
behavior difference.  We may need to change our detection code yet again to try
to be compatible with the "popular" OS.

But, the command/data/status transport over USB mechnism itself isn't reporting
any errors.  So quite a lot is working...
Comment 11 Alan Stern 2006-03-09 08:51:05 UTC
Maybe the thing to do is to try a USB sniffer program under Windows.  Perhaps
some funny command has to get sent to "unlock" the device.

Comment 15 Alan Stern 2006-03-10 12:00:23 UTC
I didn't notice anything of interest in the AUSB log.  On the other hand, it
doesn't show you trying to write anything to the drive; the only I/O commands in
the log are reads.  On the third hand, it does show that device is reporting
that it isn't write-protected.

Of course, your Linux debugging logs also showed the device wasn't
write-protected when you first plugged it in.  It didn't become write-protected
until later, perhaps when you restarted the USB subsystem.

What you should do is a fresh test.  Plug in the drive, let the errors occur,
and don't restart anything.  Then post the output from the dmesg command instead
of the contents of the system logfile.

yet another log...

Everything like before but this time I created new file on device and write
something to it.

About 'fresh test' - I did that at first but usb monitor didn't (auto)start, so
I replugged device using program and this time monitor start working. I tried
also monitoring external usb hub, in hope that it will show all traffic but
that program show only one specified device (which must be connected). Maybe
you know some better program ?

unusual_devs entry for the Pentadrive

It's possible that this patch will help.  It will stop Linux from issuing a
"Prevent Medium Removal" command, which I don't recall seeing in the Windows
log.

By the way, are you sure that the device's password is disabled?
Comment 20 nissarin 2006-03-11 16:56:03 UTC
I applied that patch to 2.6.16-rc5 but unfortunatelly it didn't help. And yes -
password protection is disabled, however afaik when password is set, then
protected drive is reported as removed and public one is accessible (on
windows). On linux, after inserting device second drive is accessible  - I can
see sdb, sdc and sdc1 (looks like password protection on ?) but restarting
hotplug allow me to mount both drives (now there is also sdb1). 

Is it possible to force that device to be rw (using unusual devs table) ?
Comment 21 Alan Stern 2006-03-11 17:29:32 UTC
The problem here isn't just that the device reports itself as write-protected. 
In fact, it doesn't report itself as write-protected at first.  The problem is
that it responds to READ commands with an error (Medium Error: Unrecovered read
error).  You'll see those errors if you read through your log in comment #18.

But then when you restart the USB system, the device obeys READ commands and
does say that it is write-protected.  I don't know why it changes its behavior
or what Windows does differently.  I'll have to go through your sniffer log more
thoroughly to try and find out; at the moment I remember only that those Medium
Errors did not occur.

You can force Linux to skip the write-protect determination step by modifying
the patch I sent.  Where it says  US_FL_NOT_LOCKABLE, change it to

    US_FL_NOT_LOCKABLE | US_FL_NO_WP_DETECT ),
Comment 22 Alan Stern 2006-03-13 07:54:44 UTC
Looking again at your sniffer log, I see these differences between Windows and
Linux:

  Windows sends a Set-Interface request for altsetting 0 and Linux doesn't.  I
doubt this makes any difference because 0 is the only altsetting the device has.

  Windows sends a READ FORMAT CAPACITIES command for both LUNs and Linux
doesn't.  Again I doubt this makes any difference.

  Windows sends INQUIRY and READ FORMAT CAPACITIES for LUN 0 and then INQUIRY
and READ FORMAT CAPACITIES for LUN 1, before trying to read from LUN 0.  Linux
sends an INQUIRY to LUN 0 and then tries to read it before sending an INQUIRY to
LUN 1.  This could be significant.

You might be able to get Linux to behave more like Windows if you do this before
plugging in the device:

    modprobe usb-storage
    rmmod sd-mod

Post the dmesg log showing what happens when you try this.

Comment 24 Alan Stern 2006-03-16 07:53:52 UTC
Okay, that didn't help.

I don't know what the problem is.  Almost exactly the same READ(10) command
succeeded in Windows and failed in Linux.  The only difference (which might be
an important one) is that Linux asked for 8 sectors to be transferred and
Windows asked for only 1.  It was the very first sector on the device, the
sector containing the partition table.

I don't know any way to force Linux to transfer just a single sector.
Comment 25 Matthew Dharm 2007-02-27 10:09:34 UTC
I think we're all stumped on this one.  Unless someone has a brainwave, let's
close this.
Comment 26 Alan Stern 2007-02-27 10:57:59 UTC
The problem might very well be the same as the problem reported by Vaclav Barta
in this thread:

   http://marc.theaimsgroup.com/?l=linux-usb-users&m=116602219816

You can read the messages in the email archive to see all the different things
we tried.  In the end it turned out there was no way to change the kernel to
make the device work.  But there was a solution involving the plscsi program. 
It is described in the last few messages of the thread:

   http://marc.theaimsgroup.com/?l=linux-usb-users&m=117027568924140&w=2
Comment 27 nissarin 2007-02-28 16:17:30 UTC
Well, it looks pretty much the same and yes, plscsi also works in my case. To
bad that there is apparently no way to make it work 'out of box'.
