Hi... here is a patch for the vendor/device codes for the
Samsung SPH-i500 Palm phone.

here is an unusual_devs.h entry which makes two different USB MP3 players
work with Linux' USB storage driver. They share a core chip, the t33520 USB
flash card controller by Trumpion microelectronics. They also share the same
ID 0x090a:0x1001, which is a "generic" ID for t33520 devices using bulk-only
protocol (0x1002 is for CB).

About the MP3 players:
  - I own an apparently unbranded one (sold in masses on ebay.de) which
    needs US_FL_MODE_XLATE (and used to need US_FL_START_STOP before its
    removal).
  - Theodore Kilgore (who created the 0x090a:0x1001 record in the
    Linux-USB device overwiew) has a "Trumpion Digital Research MYMP3"
    which needs US_FL_MODE_XLATE and an explicit US_PR_BULK.
Of course the different players report the same firmware rev. 1.00,
despite their obviously different behaviour. Ugh.

There are more players with this ID, the "Kaser Yofun 100 MP-3" (also
rev. 1.00) being one. The proposed entry may or may not help them, but
it shouldn't break working ones in any case. It is not unlikely they too
will need US_FL_MODE_XLATE.

Below you'll find my /proc/bus/usb/devices with mounted MP3 player and a
patch against 2.4.25-rc3. Please apply.

Please apply the attached patches instead. People have tried it on several
different Pentax cameras (including 330 GS)

Here's a small patch changing the GNU-style initializers to C99
initializers. The patch is against the current BK.

`debug', indeed.

I have attached a patch which contains a driver and documentation for
the MicroTouch (14-206) USB Capacitive Touchscreen controller.  It based
on some older code that I have been using for quite some time now (since
2.4.17).  This new version has been completely re-written, and now uses
Linux Input.  Greg, It would be great to possibly get it into 2.6.4.
Please let me know if I have it all wrong...

Unfortunately, the X11 mouse driver only seems capable of handling
relative data rather than absolute.  Hopefully some one will create a
suitable X11 driver capable of accepting absolute data from Linux
Input.  If anyone is aware of one, please let me know.  Otherwise, I
will most likely begin some work on a patch for GPM.

Calibration support will be on the way soon, but I'm not sure of the
best way to implement.  Perhaps some abstract functions could come
available in evdev which can call vendor specific commands for the
calibration within this driver (and perhaps others).

I have altered kbtab.c a bit in anticipation of an XFree86 4.3 driver
that can accept the pressure data (as a third axis) by listening on the
event interface.

I have set it so that if the option kb_pressure_click is -1 it  reports
pressure rather than clicks.

I've taken the old GATOS version of the ati_remote driver and done
some cleanup/rework of it while porting to 2.6 kernels.

This is a minor update to the patch I sent out about a week ago.
The key change is to use the I/O watchdog while doing ISO streaming.
Bernd Porr reports that a VT8235 system needs that; it seems like
IDE activity can interfere with the delivery of USB IRQs.


EHCI periodic scheduling updates.

 - Initial version of full speed ISO transaction support.  This
   should handle OUT transactions, such as those for usb speakers.
   For now, it's controlled using an EXPERIMENTAL config option:

   * I've run into interesting differences in how different USB 2.0
     hub silicon (the transaction translators) handle some older
     audio devices.  Needs more investigation.

   * Interrupt transfer scheduling doesn't yet cope well with schedules
     where every slot already has activity.  For now, don't plug in
     devices like hubs, mice, or keyboards while EHCI is streaming.

 - Protect freelist for highspeed ITDs, using spinlock.  Could be
   an issue for some drivers.

 - Kick in the I/O watchdog timer (5 msec) for periodic transfers.
   In this case, IDE activity on a VT8235 lost the IRQs which should
   have kept the ISO stream active.  Queues shorter than 5 msec are
   not going to work on all USB hosts.

 - Simplified the ISO scheduler:  doesn't attempt to re-schedule
   after lossage, or to short-circuit scanning.  (Rescheduling will
   probably come back later ... for now, the "hard" error here is
   highlighting problems that need attention.)

Adds two new gadget-side utility functions, to support a declarative
style of managing usb configuration descriptors.  The functions fill
buffers from null-terminated vectors of usb descriptors, which are
simple to build or update.

The "ethernet" gadget driver currently has the most interesting config
descriptors.  This uses those functions to replace some complex code with
simpler static declarations; result, it's cleaner.  (And it'll be easier
to add RNDIS configurations later, too.)

Memory savings (or cost, depending on config) was less than 50 bytes;
nothing worth worrying about.

Well, Martin Pool notwithstanding (see

http://marc.theaimsgroup.com/?l=linux-usb-devel&m=107642806303815&w=2

), it sure looks like this doesn't need an unusual_devs.h entry.

Greg, please apply this patch.

I tried using the kl5kusb105 driver for a 3Com PalmConnect USB device I
had lying around.

It oopses during device detection. There is a nested loop using the same
loop counter as the outer loop - causing the code after the nested loop
is first executed to have an invalid counter. The counter is then used
as an array index, causing a NULL deref.

Fix attached.

Nothing in life is assured...

This patch tightens up the conditions under which an auto-sense will be
cleared.  It also fixes the comment associated with the code.

This one-liner removes an unneeded macro.

This patch changes some error checking so that some bogus devices (like the
Fuji Finepix 1400) will work.

This is basically relaxing a test on a field that the spec says "should
always be zero"

Our friends at sony are at it again.  The DSC-T1 needs a new entry.  Note
that it's the same VID & PID as the last entry, but different version.

This patch is from Stephen Hemminger.  I modified it slightly to place the
new elements at the end of the complete_list instead of at the front.

Quite right; this is needless complexity.  (But note you left in a couple
of lines that should have been deleted.)

This patch changes the result code returned by the UHCI driver for a
certain class of errors.  Under a number of circumstances a USB device is
obliged to send a response packet within a fairly short turn-around time,
typically 1 - 10 microseconds depending on the bus speed.  Failure to do
so is a protocol error and should be reported as such, not as a timeout,
which is really a higher-level concept.  I believe the EHCI driver already
does this.

I trust nobody will object to the update this patch adds to
Documentation/usb/error-codes.txt, making this more explicit.

In a vaguely related change, the patch corrects the terminology in a few
comments.  The parts of a control transfer are called "stages", not
"phases".

This patch re-initializes the UHCI Interrupt Enable register following a
PM resume.  Apparently some systems clear the register during suspend,
which causes obvious problems later on.

Wonderful.  Thanks a lot for all your SMP testing, it's been a big help.


This patch corrects an error in the dequeueing code for UHCI.  Improper
locking caused it to hang in the oddball case where an URB was unlinked
even before it had been queued.

How about this?

Thank you for sending this.  Greg, here's the patch.

This patch is the first of several planned fixes for the cyclades
multiserial cards driver.

Its mostly a sync with in-house driver:

- Prevent users from opening non-existing Z ports
- Implement special XON/XOFF character handling in Z cards
- Prevent data-loss on Z cards
- Throttling fix for Z card
- Only throttle if CTS/RTS are set
- Fix accounting of received data

Kudos to Cyclades R&D

PRD_ENTRIES is specified to be precisely 256; on platforms where
PAGE_SIZE varies from 4KB the calculation in the current expression
defining it is inaccurate, which may cause crashes. This patch changes
it to the constant literal 256.

From: Andrew Morton <akpm@osdl.org>

Use sector_t for the block number.

Noticed by Marcel Cotta <mc123@mail.ru>.

ide_init() always initializes system_bus_speed variable
so system_bus_clock() should never call ide_system_bus_speed()
and no driver is calling ide_system_bus_speed() directly.

Bug was that if no IDE kernel parameter was given during boot
system_bus_speed will be zeroed in init_ide_data().

This patch should fix the problem
(as a bonus -> no need to zero these variables they are static).

Add UDMA6 support to ALi PCI IDE driver.
Forward port from 2.4 and a patch from ALi.

Was in -mm for a long time...

Fix from jgarzik's sata_sil.c libata driver.

This was in -mm for a long time...

This switches alpha to use drivers/Kconfig instead of including most of
files included by drivers/Kconfig, thus enabling previously omitted i2c
(already used in some drivers available on alpha) and telephony drivers.

Because drivers/message/fusion/Kconfig was included only conditionally
("if PCI"), this patch also changes CONFIG_FUSION to depend on PCI.

(these changes were consulted with Christoph Hellwig in "i2c on alpha
- used but not available in 2.6.3" thread on LKML)
