No usb sensors possible

[Newcomer81]

Hello, i'm configuring my V0.2 with BTT Pi1.2 and BTT pico. I have flashed Fly ADXL and Klipper expander. Wether i activate my ADXL or expander cfg, klipper won't start.
Log:
mcu 'expander': Starting serial connect
mcu 'expander': Unable to open serial port: [Errno 2] could not open port /dev/serial/by-id/usb-Klipper_stm32f042x6_1C000E00115330374E333320-if00: [Errno 2] No such file or directory: '/dev/serial/by-id/usb-Klipper_stm32f042x6_1C000E00115330374E333320-if00'

if i search via SSH it will be found.

Where is my mistake?
