Hi, i would like to use USBtoCAN FD on Ubuntu V20.04. Do i install ECI driver or SocketCAN to use USBtoCAN FD?
Hello,
You should be able to use the socketCAN driver. See the table at the bottom of this page: Driver and Software Support for Ixxat CAN Interfaces
Hi,
At what condition, then i use ECI driver?
Hi @ckwan,
I reached out to a colleague who is much more knowledgeable in the two drivers.
I was not accurate with my last comment both drivers support CAN FD. The key difference is that the ECI driver is defined by US (HMS/IXXAT) while the SOCKETCAN is an open source “standard”.
The ECI driver has a bit more implemented then the SocketCAN driver. With things like Time stamps for CAN messages, Self-Reception-Functionality, ECI uses the functions instead of the ASCII commands used in the SocketCAN.
My colleague recommended downloading both and comparing the two. Please note the ECI and SocketCAN can not be used simultaneously. The ECI has to be unloaded using the SocketCAN and vice versa. Please note, that our actual SocketCAN driver does not run with the current version of Ubuntu (with the Linux Kernel 5). We are working on a beta that will have support and we expect to release soon.

Hi Deryck,
Thanks for clarifying ECI and SocketCAN driver.

Your welcome, Here is a quick chart that might help as well.
ECI & SocketCAN comparison
| Feature | ECI | SocketCAN | Description |
|---|---|---|---|
| CAN support | V | V | |
| CAN-FD support | V | V | |
| LIN | V | - | |
| 4xCAN/CAN-FD | V | V | |
| API designed by | HMS-IXXAT | Open Source Community | Simply change of hardware manufacturer is possible using the SocketCAN |
| API concept | HMS-IXXAT-ECI-API | open Source SocketCAN-API & ASCII commands in shell | |
| Time Stamp | V | V | |
| Self-Reception | V | - | |
| implementation | Kernel mode / User mode | Kernel mode | |
| operating system | Linux & VxWorks & INtime | Linux |
Thanks Deryck for the nice comparison chart.
Hi Deryck,
Is there any update on thh SOCKETCAN driver for more recent Ubuntu releases?
I’m working on Ubuntu 22.04, and I’d like to use python to interface with my USB-to-CAN V2 compact - I was going to use python-can, which only provides support for the SOCKETCAN driver interface, not the ECI driver interface.
Hi @kkuzemchak,
You should be able to use the version I posted here:
