Reading from hiddev file failed.

[humanoidcreature]

Hi kmicki,

I'm trying to make the gyro work on steam deck, but I'm facing some issues. Latest version of the repo is installed, the correct Wii U controller is selected in Cemu, I removed the DSU controller input what Emudeck installed. I think I checked everything what I can, but still no gyro in botw. Here's the status while cemu is running:

And here's the log: sdgyrodsu.log

[kmicki]

Please run command

cat /dev/usb/hiddev0 > hiddevlog.hex

and after a few seconds press CTRL+C to interrupt it.

Then please upload here the created hiddevlog.hex file.

[humanoidcreature]

hiddevlog.zip

I couldn't upload .hex file here directly, so I put it into a zip file.

[kmicki]

For some reason your hiddev file behaves differently than mine. I hoped such things will be consistent between one Deck to the other.

I would like to prepare a test version with a fix for you to test - are you okay with it?

[humanoidcreature]

Yes, sure. I'm up to it.

[kmicki]

SteamDeckGyroDSUSetup.zip

Above is the link to the test binary package. Enter following commands to install it on Deck:

cd
wget https://github.com/kmicki/SteamDeckGyroDSU/files/8798561/SteamDeckGyroDSUSetup.zip
unzip -o SteamDeckGyroDSUSetup.zip
cd SteamDeckGyroDSUSetup
./install.sh

Please check if that works for you.

Source of the test package is at hiddev_test branch.

[humanoidcreature]

Wow it's working, really amazing. You handled it really fast! :)

By reading the status a few warnings still present, but I didn't notice any hiccups with the bow:

[kmicki]

Great, thank you for testing. I see in the logs that every now and then there is a problem with reading the hiddev file for a few seconds, but missing frame count is not high, so they get replicated and you do not notice hiccups. Other warnings are a normal thing in the current version.

I still don't understand why the data looks different on your machine. Do you have Steam started or not during testing?

[humanoidcreature]

No problem. :) Steam is running. I need it to be able to run Cemu through Proton. What's the difference exactly? Can it be related to character coding? (I'd be surprised, but who knows...) But anyway, only the Steam virtual keyboard is hungarian, everything else is english. Also I have the lastest beta OS on the Deck.

[Crono141]

not to hijack this issue, but how did you go about removing emudeck version of this? I'm getting some weird behavior as well and I'm trying to troubleshoot and try this test version. Thanks.

[kmicki]

@Crono141 when you run the commands in the other comment, the test version will replace the one installed by emudeck. See also #15 - another issue that happens when using Cemu from Emudeck.

[Crono141]

thanks. This fixed me.

[Oktavian76]

Hi, I seem to have the same issue. Gyro does not work, logfile has lots of "Reading from hiddev file failed". First I tried the original version of DSU, but I also installed the version from this issue, both with the same behavior.

Any ideas? sdgyrodsu.log

[kmicki]

@Oktavian76 Your issue is a little different. From the log it looks like it should work. I see also that 2 clients are trying to connect to the server. Try the solution from #15. If that doesn't help, please try PadTest - run it when Cemu is not running. You have to do that from another PC or add it as a non-steam game in desktop mode and force Proton in properties.

[Oktavian76]

I just tried what you suggested. First I switched back to the official version of DSU. Then I started PadTest on another PC and connected it to the Deck. This works fine, I can see the movement.

Then I started Cemu again. GamePadMotionSource is set to DSU1 and "by slot". In Input Settings the controller is "Controller 1 [XInput]", under Settings no "Use motion", it is grayed out. No other controller selectable.

The Cemu I use is not from Emudeck but directly downloaded from their page and manually added to Steam.

dsu.log

[kmicki]

@Oktavian76 That means that Cemu is not responding to data. Please confirm that in Input Settings there is 'WiiU Gamepad' selected as a controller nad not Pro Controller.

[Oktavian76]

Just doublechecked, "Emulated Controller" is set to "Wii U GamePad"

[kmicki]

What game do you test? In BOTW there is a setting in the system menu to enable gyro aiming.

[Oktavian76]

Yes, sometimes it is so easy. Before installing your software I use gyro from the SteamDeck to help aiming, so aiming with gyro in BOTW was disabled. Now after enableing it also in the game it works fine. Thank you for your help.

[kmicki]

Fixed in v1.11.

[Berinkton]

Hello kmicki,

your software worked great up until the SteamOS 3.2 Update and now i have the same problem as @humanoidcreature.

I am running the newest version (v1.13) and my Cemu settings have not changed since the working state (before SteamOS 3.2). Every thing in Cemu and Cmuhook is configured as it should be and as it was when it worked.

The log sdgyrodsu.log and the hiddevlog.hex hiddevlog.zip

i hope you can find a solution.

[kmicki]

@Berinkton 2 clients try to connect to the server. Check this comment.

[Berinkton]

@kmicki Thx its fixed 😅
