what did you mean with lsusb? Command not found.

it just lists the usb devices on the pi (to be run in ssh shell or terminal. but as long as the script said it couldn't find /dev/ttyACM0 then odds are its a connectivity issue

I bought jesterday a new usb type B Cable so there should be no reason for. Else ones flying around here aren't working too.

Pretty much any cheap usb hub would do. Also try other ports, or a different PC or laptop.

Seems not. Same issue like you have to use a USB Type C Charger to power up the Duet and RPi at the first Preconfig.
My new USB Power Hub with Power Plug makes no difference but seems to be USB 2.1 and has to low Voltage Output.

it is possible there is something wrong with the board, but thats less likely as it was responding to dcs for the update.

you're connecting the micro usb port of the duet 3 to one of the full size usb b a ports on the pi? the pi doesn't need drivers to see the serial port, which is why its often a better alternative to windows.

you can install lsusb with sudo apt install usbutils but it should be present, and it most likely won't show anything of interest as the pi isn't detecting the duet.

dmesg | tail -n 20 may be more relevant, shortly (a second or two) after plugging the usb cable in the duet.

K, Thanks. I will sort that out tomorrow.

It fails to connect longer.
I just followed the instructions and gave it a Reset with a jumper on erase. Any else i could do?
Can't I run it from its own Micro SD with its firmware and remove the Pi?
The powered usb Hub didn't help at all to flash it from a PC. I think 5 Volt on its output is still to low and it must be a usb 3 Hub with quick charge function which are quite expensive.

duet doesn't support usb3 nor quick charge, but depending on what is connected to the duet most usb ports should be able to power it (disconnect any displays if you think you have a power issue)

if you didn't get a serial port before or after trying the reset jumper then there isn't much left to do.

not if the firmware erase was successful, then it will need flashing; if you had created your own topic I might not have suggested erasing the firmware based on the output of one of the earlier posts.
new problem, new topic, please.
