Seems support for KVASER_USB already without installing.

Check ip addr:

Seems no can interface (and it's not connected).

# 2. Connect kvaser leaf:

Check ip addr:

Still no can0...

dmesg:[ 543.068096] usb 2-4: new high-speed USB device number 4 using xhci_hcd [ 543.191792] usb 2-4: New USB device found, idVendor=0bfd, idProduct=0120, bcdDevice= 0.01 [ 543.191803] usb 2-4: New USB device strings: Mfr=1, Product=2, SerialNumber=0 [ 543.191809] usb 2-4: Product: Kvaser Leaf Light v2 [ 543.191815] usb 2-4: Manufacturer: Kvaser AB



# 3. Try start services and conf if

## Services
Start services:

$ sudo modprobe can_dev $ sudo modprobe can $ sudo modprobe can_raw $ sudo ip link set can0 type can bitrate 125000

Conclusion:
Cannot find can0.. Need to install kvaser driver..


# Insall kvaser socketcan 3.10

## 1 unplug kvaser leaf

## 2 untar driver source

cd kvaser tar -xvf socketcan_kvaser_drivers_for_3.10.tar cd socketcan_kvaser_drivers/


NOTE: The socketcan_kvaser_drivers_for_3.10.tar  was recived on request from kvaser support. Their normal socketcan driver will not support kernel 3.10.

## 3 make 
Read the README file in kvaser driver.
These commands are from that README:

$ sudo make uninstall $ make $ sudo make install


Fails at make...
Seems the paths are worng for a centos system..
Need to look into makefile
/home/anderssandstrom/sources/e3-ecmc_plugin_socketcan/kvaser/socketcan_kvaser_drivers


sudo  yum install kernel-devel
The sources are at the wrong place.. Sources for wrong kernel..

# THIS IS A SIDE NOTE for PEAK usb CAN interface !!!

Check if support for PEAK USB

Use kvaser

Kernel 3.10

1. First test without install of driver and without kvaser leaf connected.

CONFIG_SPEAKUP is not set
