ALVR on Fedora and Pico 4, Install APK "Failed to find connected device", how can I fix it?

[crisp belfry]

Greetings!
I installed ALVR on Fedora, in order to play on Steam with a Pico 4, which I connected with both an USB cable to the PC, and connected the Pico 4 to the same wifi network. Following the ALVR tutorial, when clicking on the "Install APK" button, it throws and error "Failed to find connected device". When clicking on Launch, the Wired connection menu says Unknown, and Disconnected, despite having a physical USB cable between the PC and Pico 4. What can I do?

I ran the install.sh and I believe I successfully copied the 51-android.rules file to it's destination. What is the next step?

It reads as
`/android-udev-rules# adb devices
List of devices attached

`
Including the empty space.
I assume this means the software doesn't connected to the Pico 4. ALVR's response is unchanged. What should I do?

The cable worked previously on windows on the same and other computer. I also tried all 3 ports of the laptop.

Is it possible to download the APK to the PC and manually place it onto the Pico 4? I can access it's storage like a pendrive through the file manager.

Funnily, I can access the Pico 4's storage just fine with the same setup, and even the headset itself says it has an USB connection, albeit be it a 2.0 one (weirdly, every port on both computers are 2.0 by the headset using different cable, although I don't know if they are USB 3.0 certified). Wierd. I don't understand either.

I successfully installed the apk on the headset, it reads a hostname and an IP address, but it doesn't connect neither by cable or wireless.
The launcher says I'm missing some sort of HEVC encoder (which I don't know what it is), and my gpu might not support it. I have a 3070 Ti laptop version. Does this particular gpu support what it needs?

[crisp belfry]

Because I don't know what that is, I assume I did not. How can I add it?

[crisp belfry]

I successfully added the launch command through steam, and checked if the path is correct. The issue persists, ALVR can't find the headset.

did you click the launch steamvr button first?

My steps:

• Turn on computer, Steam opens automatically
• Turn on headset
• Open ALVR launcher on PC, click launch
• Open ALVR on headset
• Click Launch SteamVR in the ALVR launcher, it reads in a yellow box "The streamer is not connected! VR headsets will not be discovered [Launch SteamVR button here]"
• Steam launch a game window pops up. Three windows appeared, one is SteamVR 2.9.6 (the little steam UI themed one which also appears on WindowsOS), a settings windows with menus like general, play area, controllers, video, startup/shutdown and OpenXR, and a window with galaxy colored homogeneous background (so not plain black), but otherwise no other content.

SteamVR has green symbols, and it reads "Headset standing by Move your headset to wake it up."

Yes. Also in the bottom left corner it reads "SteamVR: Connected" (Connected in green font)

I have one single router in the flat (so not multiple extenders or such), and the computer is connected to that via cable. The headset is connected to the same network, albeit the router being dual band it has a 5G and 2.4G network, the headset is currently connected to the 5G one.
