KUSBA cannot get to work

I have tried everything I can think of and read all of miklschmidt recommendations. I must be close.

adxlmcu.cfg

As the error says, you've put serial: in your adxl345 section. @tracyb7734 ~~i think you missed most of what i wrote in #ratos-development~~ just noticed i didn't actually mention naming the [mcu], that's my bad. Your adxlmcu.cfg should look something like this:

[mcu usbadxl]
serial: /dev/serial/by-id/usb-Klipper_rp2040_E6624C90276D6038-if00

[adxl345 usbadxl]
# Edit the above line with the correct serial address. Use "ls /dev/serial/by-id/*" to find the MCU serial address.
cs_pin: usbadxl:PA15
# Hardware SPI Option (Better results, "Invalid ID" Klipper bug with first query)
spi_bus: sp13

[resonance_tester]
accel_chip: adxl345 usbadxl
probe_points:
   200,200,20

Hi All, I tried the same, but I'm getting a non valid serial Error [adxl345 usbadxl] serial: /dev/serial/by-id/usb-Anchor_Rampon-if00 Edit the above line with the correct serial address.

serial goes in [mcu] not in [adxl345]. Please look at my earlier comment in this thread stating the exact same thing: https://discord.com/channels/582187371529764864/1163143602684317837/1163160806037389383
