• Steam client version - 1705108172
• Distribution - Debian 12.4
• Opted into Steam client beta?: No
• Have you checked for system updates?: Yes
• Steam Logs: Yes
• GPU: AMD Radeon Graphics

Steps for reproducing this issue:

1. DualSense connection via USB
2. Enable more permissive passthrough for USB Devices
3. Start Steam

Android applications respond to pressing the buttons of the gamepad. With the help of the "Enable more permissive passthrough for USB Devices" flag, the Chromebook sees the gamepad in the "Linux development environment" -> "Manage USB devices" section, but it does not light up and Linux applications do not respond to the gamepad.
Steam Beta not downloading. Used the command in the terminal to download Steam (sudo apt install steam-installer). Steam does not see the gamepad.
There is no borealis-enabled flag in any mode (Stable, Beta and Developer). DualSenseX and DSWindows could not start at all.
As I understand it, the version of the kernel (6.6.13-01045-gac80b1d7ff0f) is truncated and does not want to change to a full version with gamepad drivers. Due to the fact that this kernel version is not in /lib/modules and cannot be downloaded, many commands do not work.

Now I am thinking about several solutions:

1. Using the command "sudo apt -t bookworm-backports install linux-image-amd64 linux-headers-amd64" the kernel 6.5.0-0.deb12.4-amd64 is downloaded. Use GRAB to replace booting from one kernel to another. Haven't researched this yet.
2. Use the command line Ctrl + Alt + F2 in Developer mode. So far, I have not investigated this issue either.
3. Change to Windows/Linux, but you will have to accept that there are no drivers for Audio and touch screen.
