UVC Webcam functional on Control Hub USB 2.0 port but fails to initialize on 3.0 port

[ftc19743]

We have a UVC webcam (ArduCam B0454) we have been using successfully this season on our Control Hub 2.0 port. We would like to move it over to the USB 3.0 port. When we do, the webcam is recognized on the USB bus and can be configured, but the FTC libraries fail to bring it online. Given that USB 3.0 is theoretically backward compatible with USB 2.0 devices, this is surprising. Below is what we see in the log when we try this. Emphasis added on a few lines.

We are keen to make this change to avoid the documented issues with the wifi chip and USB 2.0 port sharing a power supply, leading to disconnects. We had understood that it was also possible to connect a UVC webcam to the control hub USB C port, but cams connected that way are not recognized on the bus during configuration.

We would greatly appreciate any insights on how we might make this work.

Thank you,

Of possible interest: If we put a powered USB Hub (like the Rev UltraUSB Hub) in between the Control Hub 3.0 port and the webcam, the failure mode shifts to this:

I believe the smoking gun is here. Some webcams are not tolerant of USB device resets, and it looks like this is one of them. Skipping the USB device reset was one of the workarounds needed to support the Arducam OV9281 in SDK v8.2.

If you're feeling adventurous, you could try adding your camera's VID and PID to the CamCompatFeature::AvoidLibUsbResetDevice case in libuvc_internal.h

[ftc19743]

Thank you! We are definitely adventurous! However, modifying the SDK at the C++ level and rebuilding the libraries and getting those rebuilt libraries incorporated in our Android Studio build would be a new journey for us. Are there some documents around describing how to do this in general with the SDK? We think we understand the change to the code you are proposing, but not so clear on how to edit/rebuild that library?
Thanks!

[Windwoes]

The link I sent points to Extracted-RC, which is already set up to allow you build the SDK entirely from library sources. You should just be able to clone the repo and build in AS like any other project.

[ftc19743]

Do you happen to know what versions of Gradle and the Gradle JVM should be used to build this project in AS LadyBug? We have tried various combinations of gradle 8.5/8.9 and Gradle JVM 21/17 and no luck so far. Haven't gotten past gradle sync.

Here is the gradle sync error with 8.5 and 17:
Could not create task ':Hardware:generateDebugRFile'.
Cannot use @TaskAction annotation on method IncrementalTask.taskAction$gradle_core() because interface org.gradle.api.tasks.incremental.IncrementalTaskInputs is not a valid parameter to an action method.

[Windwoes]

I haven't tried to build it from Ladybug, you might need to do a side by side install of an earlier version of AS.

[ftc19743]

Backed up to last release of AS Koala and it built no problem with our tweak to libuvc_internal.h. That was with jbr-17 and gradle 7.2 Thanks!

To incorporate this into our build, is it as simple as copying the generated "~/FTCRobotController/build/outputs/aar/FtcRobotController-debug.aar" over to the corresponding directory in our team AS project?

Or perhaps the entire contents of the ~/FTCRobotController/build" directory? Or even the entire ~/FTCRobotController/" directory?

[Windwoes]

Let's start with just trying to run a sample vision OpMode from Extracted-RC and see if it fixes the issue.

[ftc19743]

Good point. Tried a controlled experiment:

• Reverted any changes to libuvc_internal.h in Extracted-RC
• Enabled ConceptAprilTag op mode
• Plugged a known-functional logitech into the 2.0 port
• Build and install

Sadly it died during initialization. Seems like something is amiss in the Extracted-RC build we did (fork/clone/build in AS).
Here is the log:

Ooops, looks like I forgot to bump some dependency versions in the gradle script for Extracted-RC when it was updated to 10.0.

Can you edit this dependency block to have the following versions?

    api 'org.openftc:easyopencv:1.7.3'
    api 'org.openftc:apriltag:2.1.0'

• After updating those depenencies, Extracted-RC built and ran ConceptAprilTag successfully with a known-to-function Logitech webcam.
• Then switched to the Arducam on the 2.0 port and ConceptAprilTag also ran successfully.
• Then modified the AvoidLibUsbResetDevice case in hasFeature() to always return true (for now) and the opmode ran successfully again.
• Notably: "[device.cpp:291] libusb_reset_device() not called" was printed in the log.
• Moved the Arducam over to the 3.0 port and the opMode.......... .............................................................................................Worked!

You're truly a team saver Windwoes! Much appreciation for your help.

We could use a couple more hints:

(1) We were not quite able to decipher the way the VID and PID are being used in libuvc. We see the 16 bit shifts, but we are a bit confused because the existing Arducam you had support for only had a 3 byte VID (0xC45) while most of the others have 4 bytes. We can report that the log reports this for our Arducam:
"found webcam: usbPath=/dev/bus/usb/001/002 vid=0x1BCF pid=0x284C serial=YL20230518V0 product=Arducam 5MP Camera Module".
Can you give us a hint on how to structure the AvoidLibUsbResetDevice case properly?

(2) We think the way to integrate this change into our robot build is to add a "libs" folder to our project and move the generated "~\Extracted-RC\RobotCore\build\outputs\aar\RobotCore-debug.aar" file from Extracted-RC to that new libs folder. Then we need to add this to the repositories block in build.dependencies.gradle:

     flatDir {
        dirs 'libs'
     }

And then replace this line in the implementation block
implementation 'org.firstinspires.ftc:RobotCore:10.1.0'
With
implementation(name: 'RobotCore-debug', ext: 'aar')
Is that even remotely correct?

Thank you SO much!

The VID is still 4 bytes, but the leading 0 is just implied. 0x0C45 is the same thing as 0xC45, just like 0.5 is equivalent to .5. That being said it should probably be changed in the code to be 0x0C45 so that it's consistent with the others.

For structuring the case you'd just want to add your VID and PID to usbconstants.h and then add case like:

 case makeVidPid(VENDOR_ID_ARDUCAM2, PRODUCT_ID_ARDUCAM_B0454):

Yeah that's roughly the right idea, but you might have issues with the other libraries that have a transitive dependency on RobotCore. You might have to add a gradle exclude block to those to block them from still trying to pull RobotCore from maven.

However it may just be easier to copy-paste your TeamCode source files into Extracted-RC and use that as your primary repo.

The other question though is one of legality. In the past, the game manual expressly prohibited modifying the portions of the SDK which are packaged as binary .aar files, which is exactly what we are doing here. This year's game manual appears to be silent on this topic, so I'm not sure if it would be an issue or not.

Thanks for the heads up.

We are so close. We modified the uvc code as you suggested and tested and its all good. Now just a matter of incorporating that tweak into our build.

We tried adding the updated robotcore aar to our build but couldn't even get gradle to find it on a sync. We'll keep working on that.

We also tried incorporating our code (and a couple of additional library dependencies like Acme Dashboard) into our fork of Extracted-RC but that build failed with a cascade of duplicate java symbols like this:

Duplicate class com.google.gson.DefaultDateTypeAdapter found in modules jetified-RobotCore-8.2.0-runtime (org.firstinspires.ftc:RobotCore:8.2.0) and jetified-gson-2.8.0 (com.google.code.gson:gson:2.8.0)

Thoughts on that?

This smells very strongly of one or more library authors incorrectly using implementation or api for the RobotCore dependency, rather than compileOnly.
