[Lenovo B490s] hdapsd failed with "Could not find a suitable interface" on 12.04.5

[Po-Hsu Lin]

CID: 201307-13943 Lenovo B490s

There is a working accelerometer on this system:
[ 8.826401] input: Acer BMA150 accelerometer as /devices/virtual/input/input6

But the hdapsd does not work as expected on this system
ubuntu@201307-13943:~$ hdapsd -d /dev/sda
Wed Sep 10 04:09:53 2014: Starting hdapsd
Wed Sep 10 04:09:53 2014: Could not find a suitable interface
ubuntu@201307-13943:~$

(This error message could be found on other HP system which has a working accelerometer as well, but the description of this package indicates that: "HDAPS daemon for IBM/Lenovo ThinkPads and Apple iBooks/PowerBooks", I think the outcome on those HP systems are expected)

Hi and thanks for the report.

- You have to run hdapsd as root for it to work, not as the ubuntu user.
- please give just the device name (sda), not /dev/sda
- even if you do all that, I fear your accelerometer won't be supported by hdapsd (but I am at work right now and did not have a full look at your dmesg/lsmod)

Btw, I think the Lenovo B490s is not a ThinkPad, but just a Lenovo laptop. Yet it would be cool to support it :)

[Po-Hsu Lin (cypressyew)]

Hello, thanks for the hint!

But yes, it's still not working with "sudo hdapsd -d sda", failed with the same "Could not find a suitable interface" message.

[Evgeni Golov (evgeni)]

Hi,

sorry for the delay. Could you please post the output of debug.sh, running as root?

Cool thanks,

as expected your machine has no (currently supported) way to read out the movements. But the "Acer BMA150 accelerometer" looks like a good entry-point.

Are you familiar enough with Git and building software, so I can give you a Git tree to test later? Or should I prepare some test-packages when I think I have working code?

[Po-Hsu Lin (cypressyew)]

Hello, thanks for looking into this.

I am not an expert with Git, but I would love to give it a shot.
Thanks

[Evgeni Golov (evgeni)]

Okay, here we go: https://github.com/evgeni/hdapsd/tree/acer

The following should get you up and running:

- clone the git repo:
  git clone https://github.com/evgeni/hdapsd
- check out the "acer" branch
  cd hdapsd && git checkout acer
- run autogen.sh
  ./autogen.sh
- build the code
  make
- run hdapsd from the source:
  sudo ./src/hdapsd -t -d sda
  (-t is for testing, it won't actually park the disk yet)

You will probably need the following packages installed:
 build-essential autoconf automake libtool

Also, could you please install "umockdev" and post the output of the following command:
 sudo umockdev-record /dev/input/XXX
or
 sudo umockdev-record /sys/class/input/XXX
where XXX is the input event device of the accelerometer

[Evgeni Golov (evgeni)]

ping?

[Po-Hsu Lin (cypressyew)]

Hello, sorry for the late reply,

I tried with the repo, but it's still complaining about "Could not find a suitable interface"

And here is the output form umockdev-record
ubuntu@201307-13943:~/hdapsd/src$ sudo umockdev-record /sys/class/input/input11

Thanks!

[Po-Hsu Lin (cypressyew)]

Also note that from the output of "ls /sys/class/input/input11/", it shows that the handler is "event10 js0" (which could be confirmed with "cat /proc/bus/input/devices")

/dev/input/event10 cannot be opened by using "sudo lsinput"
The output terminated with"
"open /dev/input/event10: Operation not permitted"

Running jstest with /dev/input/event10 or /dev/input/js0 will see this:
jstest: Operation not permitted

[Evgeni Golov (evgeni)]

That's strange. Have you run all commands with sudo?

My ThinkPad X201s exports two joystick devices: "ThinkPad HDAPS joystick emulation" and "ThinkPad HDAPS accelerometer data". I tested my code with both of them, and they seem fine.

Calling "sudo lsinput" does properly list them, and calling "sudo jstest /dev/input/jsX" produces working output too.

I would guess that as soon the joystick device actually works using jstest, hdapsd will pick it up just fine too.

[Po-Hsu Lin (cypressyew)]

Yes, both jstest and lsinput were executed with sudo.
And I always got the "Operation not permitted" error :(

Pretty weird.

Here's an attachment for a HDAPSD-working system (Lenovo Thinkpad T510).

[Evgeni Golov (evgeni)]

Heh, thanks. But I actually have enough of these for testing here. Real ThinkPads are easy. It's your Lenovo/Acer mashup that makes problems here :/
