I am trying to figure out what this field does? I read the manual, but I still do not understand its purpose, can somebody explain what it does?

Is this device supported for use with the Linux SocketCAN drivers?

When I plug in a PCAN-USB device and run dmesg, Linux recognizes the device number that is flashed to it and correlates it with a can network device number. Is there any way I can programatically get this info (can0 -> device 8)? It would be useful when I attached multiple PCAN-USB devices.

*Note ...

Reinstalled new drivers (8.2) Seems to be working. Thank you.

Hi,

I have some code that allows me to read data off multiple CAN buses (I have 4 PCAN-USB Pro FD devices); however, sometimes I would be unable to read from some of the CAN buses and I would have to unplug and replug the devices to get it to reset. (Is there any way I can reset the channel without ...

Every time I restart my machine and try to access the devices using the API, I get the following error:

1482445262.149631: ERROR: failed to scan directory (errno=2) '/sys/class/pcan'
1482445262.149641: ERROR: failed to open file (errno=2) '/sys/class/pcan/version'

In order to get it to work again ...

I read the PCAN-LIN protocol definition and it looks like LIN messages can be written/read through the CAN interface.

So to be clear, would this setup work for a linux environment:

Linux computer -> PCAN-USB Pro FD -> [PCAN-LIN device] -> LIN Device

I would have to write code on the Linux side ...

I've attached two screenshots. One with PCAN-USB Pro (Successful) and the other with PCAN-USB (Unsuccessful)

Hi Michael,

Thanks for the reply. Are there examples on how this would work? If I wanted to send and receive LIN messages using this PCAN-LIN module?

FYI: I installed 4 PCAN-USB Pro devices (but I removed them when I ran these commands).
