XVF3800 HID and LED control

[Pseudomizer]

Hello guys,

I have been trying now for almost a week to control the XVF3800 via Kotlin from Android Studio developing an App. After 3 days of troubleshooting and finally deciding to trace the device, I hooked up the XVF3800 to my Windows machine and I installed a bunch of USB analyzers and also WireShark with USBPcap. None of the apps was able to detect the press of the "mute" button.

The conclusion from multiple AI agents and myself is that you are not exposing in the USB firmware the mute button as a HID control device despite the documentation hinting towards that.

I also saw all the code for I2C and how to change the color of the LEDs to red, but I was not able to change anything via the USB firmware attached via USB to Android. It always says communication failed.

Here is my question... Can you please publish a firmware for USB which exposes those HID events and enabled LED control? If this is an educational problem, please let me know. Happy to get educated here on how to get this done. Thanks.

Hi guys,
Can someone reply if not being able to detect the mute physical button press via USB libraries is really an issue of the firmware not publishing the HID or something else?

Thanks in advance.

Here is what AI is telling me about controlling XVF3800 via USB and Android....

No, XMOS does not provide a pre-built xvf_host application for the Android OS.
The sample command-line utility xvf_host is officially supported for the following platforms:
Windows
macOS (x86_64 and arm64)
Linux (x86_64)
Raspberry Pi OS

Contact XMOS: The documentation explicitly states to "Please contact XMOS for information on using these tools on other host platforms"

Who do I have to contact for Android support?
