So conclusion is that use of "kvaser/socketcan_kvaser_drivers_1.6.113_patch_asm_3.10.tar.gz" is the only way to make it work under kernel 3.10.
According to Kvaser support this approach is OK and should work just fine. Also test shows it works well.
# OBSOLETE NOTES BELOW:
#### 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

inet6 fe80::c23f:d5ff:fe66:2544/64 scope link noprefixroute

```
Seems no can interface (and it's not connected).
#### 2. Connect kvaser leaf:
Check ip addr:
```

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...
sudo yum install kernel-devel
The kernel sources are at the wrong place.. Sources for wrong kernel!!
Need to update
```
sudo yum update
```
Now the kernel sources are at the corerct location. patched version of new socketcan version builds and seems to work with candump and connected pmu905
#### 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
CONFIG_CAN_PEAK_USB=m
CONFIG_SND_FIREWIRE_SPEAKERS=m
# CONFIG_SPEAKUP is not set
```
