system installation – Raspberry Pi 5 Ubuntu 25.10 How to disable USB auto suspend?

Please help, new to Linux, trying to escape from Microsoft Windows:

I have Unbuntu installed on a Raspberry Pi 5, this was done via the Rasberry Imager and selecting Unbuntu Desktop to image its SD card.

Booted and updated ok. Overall running well until I ran into the power management problem.

Just A few of my USB devices would not recover though. That is good but I have no GUI option to stop it over when back to wake state.

No sleep in power setting

There is no GUI option to disable it even though it is not a portable device.

I found also that my PI 5 does not use GRUB so I could not use any of those posted solutions.

So how can I get USB auto suspend turned off?

Thank you for your help!
