GrapheneOS-Jub Just to get back to you about the testing USB stuff;
I tried a number of USB pheriperals from USB flash drives to several hard drives, an SSD, several OTG adapters to try, gamepads, a mouse, a keyboard, a USB to (micro)SD adapter, a Yubikey, Bluetooth and WiFi adapters.
At least, alot of hardware has now been tested on Android 17. (See photo of the stuff I tried on wormhole, and again downloading is not required)

I also enabled all notification options. (Bubbles, etc)
Everything worked as advertised, I could not replicate the bug. I am on 2026062201.
Perhaps the USB port is dirty or it is a hardware issue?
I hope you can find someone who can figure it out for you though, sadly, I have exhausted my possibilities of replicating this error. I hope a developer can help you along the way, they know so much more about the system than me.
