Flashing Duet Wifi on recent MainsailOS (Bullseye) lets Duet disappear

[Roycinger]

What happened

I made a fresh install of MainsailOS via Raspberry Pi imager.
After flashing the MCU (Duet Wifi), the Duet disappeared.
It cannot be found by lsusb, nor by 'ls /dev/serial/by-id/*'.
Dmesg reports: 'unable to enumerate USB device'

While researching, I found this issue: Klipper3d/klipper#4933
Conclusion is that a Duet flashed by Bullseye cant be discovered by the OS / Klipper anymore until it's flashed by Buster based Debian.

What did you expect to happen

Successfully flashed and discoverable Duet Wifi

How to reproduce

• Install MainsailOS (Bullseye based)
• flash Duet MCU

Can confirm the issue. But it is not Mainsail OS specific, it also happens with vanilla Raspbian v11 (bullseye) and manual klipper installation.

This issue has to be fixed in Klipper. MainsailOS is just a Raspberry PI OS lite with Klipper preinstalled. Nothing more...

That's what Toskium and I figured. We agreed that this is not a specific MainsailOS or Klipper issue, that's why I crossposted.
