Attached you will find patches that will bring the Philips Webcam driver
(PWC) up to version 8.12. The most important new feature is support for
the motorized pan & tilt feature of the new Logitech QuickCam
Orbit/Sphere, which I don't think is in the stores yet (at least it's
not on Logitech's website), but should be there soon. In addition, the
documentation in the kernel about the cams is updated.

Thanks to Ralf Dietrich <ralle@envicon.de> for the information.

This patch helped Jon Wilson.  It allows devices to have a configuration
numbered 0, in spite of the standard convention that config #0 really
means unconfigured.

Info came from John Zhuge <john.zhuge@troposnetworks.com>

This patch basically eliminates the use of MODE_SENSE or MODE_SENSE_10 for
direct-access USB storage devices.  That $&%*! command has caused us more
trouble than all the others combined, and after more than a year we still
don't have a good way of handling/using them.

I constantly get complaints about devices which don't work because of the
way 2.5/6 uses MODE_SENSE and MODE_SENSE_10 -- this patch will greatly
increase compatiblity with devices.  As with the patch to limit transfer
sizes, I'd like to see this applied as soon as possible.

Matthew -

Is this patch in your queue? I don't see it in Linus' tree yet.

Don't send any MODE SENSE commands to usb mass storage devices.

This patch adds to unusual_devs.h an entry reported by Andries Brouwer and
it moves another entry to the correct position in the numerical ordering.

Thank you for sending this in.  The usb-storage driver will be updated
sometime after 2.6.0-final is released.

I send a patch and copy of /proc/bus/usb/devices for my 5`25 external
USB enclosure. I don't know exactly manufacturer of this device, but
model is CD-509.
It will be nice if it helps somebody else.

Here is another update for unusual_devs.h in both 2.6 and 2.4.  No
urgency.

Thanks for sending this in.

Yes, it seems to work OK on the 7i with this updated patch.  I don't
have a 7 or 7Hi to try, but everything on the web seems to say the USB
firmware works the same way.

I've seen some entries in 2.4.22 and 2.6.0 unusual_devs.h
for Kyocera Finecam S3 et S4 cameras and I own a Finecam S5
that does not work out of the box either
(here is the beast : http://www.yashica.com/digital/finecams5/finecams5.html)

so I found the unusual_devs.h entry and submitted it some month
ago at http://www.qbik.ch/usb/devices/showdev.php?id=1626
for the 2.4 kernels

I thought It would be nice to have the whole Finecam family
in Unusual_devs.h for 2.6.0

The patch for the 2.6.0-test9 is attached with this mail

It differs from the entry I submitted at www.qbik.ch
as I used the new SC/PR_DEVICE flags and got rid of the
IGNORE_SER flag from 2.4

Do you want a patch for 2.4 too ? If so, I should test my
old 2.4 entry with the lastest 2.4 Kernels, coz on a daily
basis I use a 2.4.20, which is rather old. Moreover, I could
used the SC/PR_DEVICE flags too for 2.4.22 (keeping the IGNORE_SER flag
though)


By the way, several entries with the running patch :

The change below is needed to get the S4 camera working.
Tested with both Optio S/S4

This is a minor cleanup that replaces a test for non-null urb->hcpriv
with "is the urb on this list".  HCDs don't need to use hcpriv in that
way, and in general this is a safer way to test that.  (AIO does much
the same thing in its kiocb cancelation paths.)

this driver has locking problems. Here's the first round of fixes
for the obvious cases.

- it makes clear differences between completion handlers and task context
- it fixes cases of sleeping in interrupt

Okay, here it is.  This patch basically just adds comments.  Each routine
that uses the new scatter-gather function gets a brief explanation of
what's going on, and access_xfer_buf() itself gets detailed comments
saying what it's doing and why it's necessary.  You may even want to cut
some of it back; I was pretty verbose.

As a result of the last round of changes, the raw_bulk source files aren't
needed any more.  They can be deleted and the Makefile changed
accordingly.

This patch changes the sddr55 driver to make it use the new scatter-gather
routines.  It has not been tested, but perhaps Andries Brouwer will be
able to try it out.

This patch updates the shuttle_usbat driver to use the new scatter-gather
transfer routines.  The small set of changes needed speaks well for the
original organization of the code.

This has not been tested.

This patch fixes the scatter-gather handling in isd200, replacing an
incorrect routine there with calls to the new routine added in the
previous patch.  It also removes a couple of places where the driver
returned data for commands that shouldn't get any (TEST-UNIT-READY and
START-STOP).

This has not been tested.

This patch adds a small utility routine for storing data in a transfer
buffer.  The next patch uses this routine quite a bit in the isd200
driver.

This patch converts the jumpshot driver to use the new scatter-gather
routines.  It has not been tested.

This patch updates the datafab driver to the new scatter-gather handling,
which makes it safe for systems with >1GByte of memory.
It has been tested by Eduard Hasenleithner.

somebody built his own version of be16_to_cpu(). Such things affect
maintainability.

this fixes the questionable error return codes Paulo noticed
in usblp. I hope I really got all cases now.

This patch updates the sddr09 driver to use the new scatter-gather access
routine.  After installing it, the user who experienced memory access
violations says everything is now working properly.

This patch adds a routine to protocol.c that correctly transfers data to
or from a scatter-gather buffer.  According to Jens Axboe, we've been
using page_address() incorrectly -- it's necessary to use kmap() instead
-- and in fact it doesn't give the desired result when the buffers are
located in high memory.  This could affect anyone using a system with 1 GB
or more of RAM, and one user has already reported such a problem (as you
know).

The three fixup routines in protocol.c and usb.c have been changed to use
the new s-g access routine.  When similar adjustments have been made to
all the subdrivers, we will be able to eliminate the raw_bulk.c source
file entirely.

This patch removes an uncalled subroutine from debug.c.  I only noticed it
when tracking down scatter-gather usage; there didn't seem to be any
reason to repair it since it wasn't being used anywhere.

This patch was written by Andries Brouwer.  It adds to sddr09 the ability
to use 64 MB SmartMedia cards.  I have added a few minor alterations to
make it fit in with my sequence of other patches.

This patch removes some unnecessary scatter-gather code from the sddr09
driver.  In its place a single smaller buffer is re-used each time through
an I/O loop, as opposed to transferring all the data at once.

Andries Brouwer kindly tested this and suggested some improvements to get
it working right.

Added vendor/product ids for Epson, Genius, Microtek, Plustek,
Reflecta, and Visioneer scanners. Removed ids for HP PSC devices as
these are supported by the hpoj userspace driver.

It improves synchronization with hub_irq() and guarantees that the hub
disconnect() routine doesn't exit until the URB's completion routine has
finished.

It changes spin_lock_save() to spin_lock() within the completion routine
and list_del()/INIT_LIST_HEAD() to list_del_init().  It's nothing more
than a minor optimization.
