Describe your issue:
…
I got a new BTT SKR 3 EZ board & am installing it on my Voron V0.2. I have followed the details for installation & I can log into Mainsail via web browser with the IP address. There is a button on the SKR board for USB or CAN & I have that set to USB (up)
I have not set up the Printer.cfg file yet as I cannot get the serial port for the MCU.
SKR 3 board is powered by 24V supply & no other cables are connected to it yet.
ls /dev/serial/by-id/* reports back ls: cannot access ‘/dev/serial/by-id/*’: No such file or directory
I found this Debian 11 (Bullseye) udev bug - No board or serial found & it turned out I had that version. It looks like the update worked & now I have:
udev:
Installed: 252.5-2~bpo11+1
Candidate: 252.5-2~bpo11+1
Version table:
*** 252.5-2~bpo11+1 100
100 Index of /debian bullseye-backports/main armhf Packages
100 /var/lib/dpkg/status
247.3-7+rpi1+deb11u2 500
500 Index of /raspbian bullseye/main armhf Packages
Unfortunately the ls /dev/serial/by-id/* command still shows “ls: cannot access ‘/dev/serial/by-id/*’: No such file or directory”
I also tried
Unplug USB
Re-plug USB
sudo dmesg
Which returned a lot of info. The only USB parts I could find are:
[ 1.570447] usb usb1: New USB device found, idVendor=1d6b, idProduct=0002, bc dDevice= 6.01

This looks like the USB hub on the Pi & not the BTT SKR 3 EZ board
However when I plug in the Klipper expander board into the Pi I get this at the bottom of the list:

Any suggestions?
