+# Use kvaser
+
+## Kernel 3.10
+
+# 1. First test without install of driver and without kvaser leaf connected.
+
+Check support before install of driver:
+
+``` 
+sudo cat /boot/config-3.10.0-1127.el7.x86_64  | grep KVASER
+CONFIG_CAN_KVASER_PCI=m
+CONFIG_CAN_KVASER_USB=m
+
+
+Seems support for KVASER_USB already without installing.
+
+Check ip addr:
+``` 
+ip addr
+1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
+    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

+
+
+``` 
+Seems no can interface (and it's not connected).
+
+# 2. Connect kvaser leaf:
+
+Check ip addr:
+``` 
+ip addr
+1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000

+Still no can0...

+# 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
+``` 
+sudo cat /boot/config-3.10.0-1127.el7.x86_64  | grep PEAK
+CONFIG_CAN_PEAK_PCI=m
+CONFIG_CAN_PEAK_PCIEC=y
