Description jmharris 2009-12-11 14:30:05 UTC

Problem with '2.4GHz Entertainment Slim Keyboard with Smart Touchpad', a combination keyboard/touchpad produced by Ortek. This is the keyboard at http://www.ebuyer.com/product/158377

Basically, the keyboard section of this device does not work, i.e. no keypresses are detected. The touchpad and meta keys (ctrl+alt+win) work correctly. All keys work correctly in the bios and grub.

This issue has been tracked so far here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/405390

Investigation has found that the keypresses are reported when /sys/module/hid/parameters/debug is on e.g.

kernel: [ 1228.799642] drivers/hid/hid-core.c: report 3 (size 5) = 03 00 02 fe 00

But no corresponding output is received at the relevant /dev/input device.

The ubuntu bug already contains attachments with debug logs when connecting the device, please let me know what other information is required to help debug this.

Comment 1 jmharris 2009-12-14 23:23:44 UTC

Output from catting the relevant /dev/hidraw device is the same as from a working keyboard, but nothing is received on the corresponding /dev/input/event interface.

Can anyone give any pointers where to go from here? If the same output is received on hidraw then what is involved in generating the evdev output?

Comment 2 jmharris 2009-12-15 23:38:28 UTC

I have now fixed this problem locally, the logical maximum value in the usb resource descriptor is incorrect for the keyboard. I worked out the value that needed fixing and modified the existing usb quirk driver for the sunplus keyboard to test it.

I need to generate a more appropriate kernel patch from my changes and submit it to whoever is responsible. If anyone can help with this please let me know, I haven't done any development in the kernel before.

The basic solution approach until a decent patch is available:

The USB resource description (for the keyboard part of the device) is:
05 01 09 06 a1 01 05 07 19 e0 29 e7 15 00 25 01 75 01 95 08 81 02 95 01 75 08 81 01 95 05 75 01 05 08 19 01 29 05 91 02 95 01 75 03 91 01 05 07 19 00 29 91 15 00 25 01 75 08 95 06 81 00 c0

When you cat the relevant rdesc for the device in /sys/kernel/debug/hid this indicates Field(1) has a usage of 146 but the logical maximum is 1. I see from the kernel source code that resource descriptor fixes have been done for other HID devices so I hacked in the manufacturer and device id (0x05a4 and 0x2000 respectively) into hid-ids.h. Then I consulted the USB specification and hijacked the sunplus keyboard quirk driver code to modify the appropriate rdesc bytes simply as follows:

rdesc[55] = 0xff;

Obviously this raises the logical maximum to 255, that may be excessive. Need to review what a sane value for this should be.

I also have the MULTI_INPUT quirk enabled by altering hid-quirks.c which gives me several more /dev/input/event devices for the keyboard and trackpad on this device, but that was done before the rdesc fix- maybe it is not important in order to get the main keyboard working.

Comparing the keyboard USB HID resource descriptor (.0002 is the media keys), Ortek Smartpad:

# cat /sys/kernel/debug/hid/0003:05A4:2000.0001/rdesc
05 01 09 06 a1 01 05 07 19 e0 29 e7 15 00 25 01 75 01 95 08 81 02 95 01 75 08 81 01 95 05 75 01 05 08 19 01 29 05 91 02 95 01 75 03 91 01 05 07 19 00 29 91 15 00 25 01 75 08 95 06 81 00 c0

... we see the Ortek's 'Logical Maximum' is incorrectly at 1, rather than 146; the apple keyboard has it set to 255.

USB resource descriptor fix in new Ortek USB HID driver for Linux 2.6.32.3

Here is a patch for vanilla linux 2.6.32.3 sources. I have followed the pattern used for other quirky devices in the kernel, so you must enable the new Ortek USB HID driver available at:

-> Device Drivers
  -> HID Devices
    -> Special HID drivers

Please let me know if there is anything further required before this can be merged.

Comment 5 Dmitry Torokhov 2010-01-11 23:56:14 UTC

Your "Signed-off-by: " for the patch and the patch in unified diff form will be appreciated. Then it's up to Jiri to pick it up.

USB resource descriptor fix in new Ortek USB HID driver for Linux 2.6.32.3 (unified diff)

Updated diff following guidelines in SubmittingPatches.

This patch adds a new USB HID driver for the Ortek WKB-2000, working around an incorrect LogicalMaximum value in the USB resource descriptor. Bug originally reported by Ubuntu users: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/405390

I have attempted to follow the same pattern as for similar buggy USB HID devices.

Comment 7 Daniel J Blueman 2010-01-20 23:24:34 UTC

I have applied the patch against 2.6.33-rc4, built and tested; it works as expected - great work!

We should get this to Dmitry ASAP (if not already done) for a late pull request to Linus, for inclusion in 2.6.33-rc5, due in a week and CC stable@kernel.org in the patch email. The CC to stable will ensure it hits the 2.6.32 kernel series, which will be the baseline for Ubuntu 10.04 LTS (though it may move to 2.6.33).

Until then, we can simply use the updated mainline kernels:

http://kernel.ubuntu.com/~kernel-ppa/mainline/

(if you have Nvidia or Radeon graphics hardware, enabling the Xorg-edgers PPA will get you better graphics support). Thanks, JM! Here is my 'Tested-by' support for any patch email:

Tested-by: Daniel J Blueman <daniel.blueman@gmail.com>

Comment 8 jmharris 2010-01-21 13:28:13 UTC

Thanks for taking the time to test this Daniel. Dmitry Torokhov commented earlier so I expect he's aware of the patch now being available in the required unified format.

Who should be ensuring stable@kernel.org is notified- or will this bug being tracked here suffice? I've not submitted a kernel patch before so I'm not familiar with the standard protocol.

Comment 9 Daniel J Blueman 2010-01-21 13:40:00 UTC

Hi Johnathon - one of us needs to present the patch in an email to Dmitry T (who's the kernel's input stack maintainer) and Jiri Kosina (USB keyboard maintainer), so they can handle it in the usual patch workflow.

The important thing is that you are acknowledged as developing the patch, and the chain of testers, which the maintainers upstream need from lack of hardware/time - are you happy I do this and get the patch off? We just CC the stable@kernel.org alias too.

Comment 10 jmharris 2010-01-21 13:45:29 UTC

Thanks for the guidance Daniel, I will present the patch as instructed.

Comment 11 Daniel J Blueman 2010-01-21 14:00:19 UTC

Great - from the MAINTAINERS file in the linux kernel:

USB HID/HIDBP DRIVERS (USB KEYBOARDS, MICE, REMOTE CONTROLS, ...)
M:      Jiri Kosina <jkosina@suse.cz>
L:      linux-usb@vger.kernel.org

INPUT (KEYBOARD, MOUSE, JOYSTICK, TOUCHSCREEN) DRIVERS
M:      Dmitry Torokhov <dmitry.torokhov@gmail.com>   
L:      linux-input@vger.kernel.org

So, also you should CC linux-usb and linux-input.

Comment 12 jmharris 2010-01-21 14:40:39 UTC

Thanks Daniel, I've emailed the people and lists involved (although unfortunately Gmail mangled the first- fixed but apologies to those that see it).

Greg KH <greg () kroah ! com> had already replied to state that whole new drivers are not -stable material however.

Comment 13 Dmitry Torokhov 2010-01-21 18:09:16 UTC

The change touches drivers/hid so it should go through Jiri's tree and not mine. I see you have him in the patch submission e-mail so he should pick it up.

Comment 14 jmharris 2010-01-26 13:58:14 UTC

Jiri Kosina reports he has applied this patch.

Comment 15 ken 2010-02-07 14:44:50 UTC

I am very new to compiling my own kernel.  I am/was using Ubuntu Karmic (9.10) and installed KernelCheck.  From there I installed the 2.6.32.3 kernel and applied the patch as provided by jharris above.  I then had to install the nvidia drivers.  After a few attempts I was able to boot using the new kernel with the nvidia drivers.

The problem I am having is that some of the Ortek keys are being incorrectly recognised.  They all appear to be recognised but not correctly. For instance, j, k, and l are being seen as 1, 2, and 3.  However the rest of the row (a,s,d,f,g,h) are all recognised correctly.  

I am not sure if this is related to this bug report.
Is there anything I should try which might be of help to this bug report?

Comment 16 Marc Warne 2010-02-07 14:59:56 UTC

ken: Although I haven't tried it myself, it's probably because you have Num Lock on. This replaces the functions of keys around the j, k, l region and maps these to the numeric keypad.

Try turning this off to see whether you have the same issue.

Comment 17 ken 2010-02-07 17:00:38 UTC

Hi Marc,

You are correct. Thanks so much.

To summarise: I have installed the 2.6.32.3 kernel using KernelCheck on Ubuntu (with nvidia drivers) and applied the patch.  The keyboard appears to work correctly for me.

It's in the 2.6.33-git7 patches at the time of writing, so expect 2.6.34 to have it if you're waiting for a full release. Ubuntu have released a kernel package for 2.6.32 with this patch already applied.

However I have been a little impatient and patched the sources for the version 2.6.31 and 2.6.33 of the opensuse desktop kernel, and in both cases the keyboard works perfectly.

In the first case the kernel version is the same as the official one and so all of the packages from the distro link with it perfectly.

In the second case I was unable to install the official drivers for my nvidia card.

Thank you very much to the coder that did the patch, it works great!

It looks like that the touchpad included in the keyboard is a synaptics one

# tpconfig -r 1
Found Synaptics Touchpad.
Firmware: 8.96 (multiple-byte mode).
Packets: absolute, 80 packets per second.

This touchpad should be capable of multitouch operation.
As the windows driver can allow it and as multitouch should be possible in at least two ways as described in this webpage:

http://blog.twinapex.fi/2009/10/11/setting-up-multi-touch-scrolling-for-ubuntu-9-10-karmic-koala-linux-on-asus-eee-1005ha-netbook/

However the xserver is not picking it up as a synaptics touchpad, in fact
even after trying both methods I get the following result:

not to mention that at the command

# synclient -l

i get the following response

Couldn't find synaptics properties. No synaptics driver loaded?

However in my xorg.conf file I have set it up as such

Section "InputDevice"
Driver "synaptics"
Identifier "Mouse[0]"
Option "Device" "/dev/input/mice"
Option "Emulate3Buttons" "true"
Option "Name" "Touchpad"
Option "SHMConfig" "true"
Option "Vendor" "Synaptics"
Option "ZAxisMapping" "4 5"
EndSection

and I can also get the following readout

# tpconfig -d /dev/input/mice
Found Synaptics Touchpad.
Firmware: 8.96 (multiple-byte mode).

Is the code of the patch maybe incomplete so that the touchpad cannot be detected properly as such by the Xserver thus preventing multitouch from being enabled?

If I give the command

$ synclient -m 100

then I get

Can't access shared memory area. SHMConfig disabled?

go figure.

I am using ubuntu 9.10 with a patched 2.6.31.9 kernel

Comment 22 Dmitry Torokhov 2010-03-22 21:55:43 UTC

NO! Please remove tpconfig utility from your system and forget about it. It hasn't been working for many years (pull the keyboard and all your mice out and it still will report that you have synaptics present).

Comment 23 Rob Davis 2010-08-13 12:23:46 UTC

Can you add:

Bus 001 Device 011: ID 05a4:1700 Ortek Technology, Inc.

To the ortek driver.   I patched my linux source and it works with your driver. (For testing I changed the USB ID you have above to 05a4:1700 with good results, but would like it to go upstream, probably in a way that both devices can work). It's the tiny keyboard they're now doing, the pkd-1700. I guess it's the same chipset as above.

It's for this hardware:

Comment 24 jmharris 2010-09-30 20:26:53 UTC

Hi Rob, thanks for confirming that. I've had mail from a couple of others with that model and it seems to have the same (or a similar) problem.

Before we submit a patch I would like to check that the PKB-1700 USB resource descriptor has the same problem, rather than just assume it does (although as it works for you, it is likely to be). Since the patch rewrites the LogicalMaximum value it would be best to check it is definitely set correctly for both models. Is it possible for you to enable debug and send me the rdesc? (As Danial did in
comment #3).

I also suspect this would be best handled by opening a new bug with the corresponding patch, if anyone cares to correct me on that assumption.

Comment 25 Johan 2011-01-07 11:45:04 UTC

Another bug has been opened regarding this issue, with a corresponding patch.
