Hi,
I am using a USB-to-CAN V2 professional to control a Maxon Epos 4 via canbus. This properly works on Windows with the VCI driver.
Now I need to make it run on a Raspberry Pi 4 using a Debian 64 bit OS. I installed the ECI driver for USB and it kind of works.
When executing lsusb, it is there:
~/ixxat/EciLinux_arm64/bin/release$ lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 005: ID 08d8:000a IXXAT Automation GmbH USB-to-CAN V2
Bus 001 Device 002: ID 2109:3431 VIA Labs, Inc. Hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
I can see it in dmesg:
[ 5154.210600] usb 1-1.3: new high-speed USB device number 5 using xhci_hcd
[ 5154.316426] usb 1-1.3: New USB device found, idVendor=08d8, idProduct=000a, bcdDevice= 1.00

When executing the demo program, i can see the device, too:

Now, sending 20480 CAN Messages

But if I try to access the device from an API delivered by Maxon Motors, this library cannot find the device or access it. Also: There is no can0 interface when performing ip addr list.
I thought I need to install the socket can driver to get the interface, but that fails, too:

As I am not that deep in drivers and modules on linux systems, any help on that would be nice.
Thank you in advance!
