Re: AW: ESD CAN-USB/2 Linux Mint 16 kernel 3.11

[Brian Gregory <bdg@theptrgroup.com>]

Thomas,

I have received this confirmation from the vendor (ESD):

---
Please note:

With the release of the Linux kernel 2.6.25 an extension was added, which
only accepts USB drivers, which are published under a GPL license, and
which code must therefore be open source. The company esd however is not
able to place their USB drivers under a GPL license and therefore cannot
offer an USB driver for the standard esd CAN-API starting from kernel
version 2.6.25.

In the mean time we found a solution for our model CAN-USB/2,
unfortunately not for the CAN-USB-Mini. There is an open source project
for Linux drivers for CAN interfaces which is called "Socket CAN". We
offer a support of Linux drivers for our CAN USB/2 modules which are
compatible to this CAN-API. Additionally to that we offer a wrapper to the
most of the esd CAN-API functionalities which is based on the Socket CAN
driver. Please note that not all esd CAN-API function calls are supported.

So you have to change to the CAN-USB/2 if you want to use later Linux
kernel versions.

Thanks for your support.
