NI can’t interface with USB device. I have verified control of the Kvaser from my PC. That’s why modules always should be built for the exact kernel version and configuration! However, manufacturers supporting their proprietary drivers is still frowned upon in the Linux world. All of my comments are in regards to my specific hardware and software configuration. The Linux system denotes each CAN bus on an interface as a channel, and sets a unqiue channel identifier. But notice, that the drivers in the branch are still under development and the drivers in the trunk except the vcan driver do not have any common configuration interface

CAN Bus –
Check which driver is loaded by Core with the provided tool. Most Linux distributions will include a linux-headers package which includes the headers used to compile the kernel.

CONFIG_CAN_KVASER_USB: Kvaser CAN/USB interface
For single-channel Kvaser CAN interfaces like the Leaflight, the circuit identifier will always be 0. Message 7 of 9. Follow these steps to update systems that have linuxcan installed but need to use socketcan drivers. The socketcan support is a completely different driver that conforms to socketcan requirements and API. The circuit identifier is an index for multi-channel CAN hardware interfaces.
I emailed Kvaser about this and their answer was this: We do not want both drivers trying to grab the same resource. And you could deploy the same source code on Windows, since the API is identical. Otherwise you could hire a kernel hacker to implement a driver fortunately, we’ve got their source code, so it shouldn’t be a big deal to find out how the device works and bring it to mainline.
Secure boot must be disabled on Ubuntu Post from BradM about building: Peter Mortensen 1, 3 14 Hypomania 1 Thank you for the reply.
The hardware identifier is unique to each physical hardware device, where each device has one or more channels. Building a kernel isn’t trivial, but hopefully my steps will kvaer fill in some of the gaps. While trying to validate the data coming in over CAN, error frames are read using the Kvaser linuxcan canmonitor example. I have verified control of the Kvaser from my PC.
Really horrible to maintain – not suited for production in any ways. In kvaswr case it was 4. In order to get the header files, I rebuilt the kernel. Message 5 of 9. And these kernel-internals change frequently.
Of course you also won’t be happy to reprogramm your web-browser when you change your Ethernet card in your system ;- Programming a netdevice driver is kbaser most cases easier than handling all the FIFO stuff and different APIs yourself when programming a character device. I found that going to http: Granted though, once one is hacked it is easy enough to repeat.
