Hi All, I decided to split my correspondence with Oliver to be very specific I have Atmel Chip on DELL 3201 board with built-in CAN port , as well as LAN and USB ports I followed Dell manual and run proposed command below > for i in /dev/ttyACM*; do udevadm info $i | grep -q 03eb_2404_USB_CAN_FD && echo "path:/dev/$(basename $i)"; done It prints the device /dev/ttyACM0 What is this device? Does it serve CAN port or USB port? Can I use it as a serial CAN device? BTH, even kernel 5.3 does not have a configuration option for ATMEL CAN device. Thanks all Lev
