+## History
+Kavser does not support socketcan for kernel 3.10.
+However the Kavser support supllied a custom driver for Kernel 3.10 for testing. 
+
+## Files
+In this dir you will find two files:
+
+1. socketcan_kvaser_drivers_for_3.10.tar
+
+2. socketcan_kvaser_drivers_for_3.10_patched.tar.gz  
+
+The "socketcan_kvaser_drivers_for_3.10.tar" is the "raw" files recived from Kvaser support. This file did not compile. Kvaser suggested to remove some lines in the Makefile. This resulted in the "socketcan_kvaser_drivers_for_3.10_patched.tar.gz" file.
+
+The "socketcan_kvaser_drivers_for_3.10_patched.tar.gz" driver compiles and installs just fine. But an error is generated when the Kvaser Leaf Light v2 interafce is connected to USB and the interface will not work:
+
+dmesg using socketcan_kvaser_drivers_for_3.10.tar (with patched Makefile):
+``` 
+Connecting leaf to usb:
+[Mar24 11:11] usbcore: deregistering interface driver kvaser_usb
+[Mar24 11:12] usb 1-2: new high-speed USB device number 10 using xhci_hcd
+[  +0.126425] usb 1-2: New USB device found, idVendor=0bfd, idProduct=0120, bcdDevice= 0.01
+[  +0.000002] usb 1-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0
+[  +0.000002] usb 1-2: Product: Kvaser Leaf Light v2

+[  +0.000007] kvaser_usb: probe of 1-2:1.0 failed with error -110
+[  +0.000027] usbcore: registered new interface driver kvaser_usb
+
+The interface is not working (not visible with ip addr).
+
+Disconnecting leaf from usb:
+[Mar24 11:21] usb 1-2: USB disconnect, device number 10
+[Mar24 11:23] usbcore: deregistering interface driver kvaser_usb
+
+``` 
+
+## CONCLUSION
+
+Use file "kvaser/socketcan_kvaser_drivers_patch_asm_3.10.tar.gz"
+This file contains a patched version of the newest Kvaser socketcan drivers. 
+Basically everything that did not compile was removed, mostly related to CAN FD. A function can_change_state() was also not availble in kernel 3.10. Kvaser support supplied a can_change_state() which have been added to the code.
+
+So the patched newest version of the Kvaser socketcan drivers is the only option for the time beeing. By using this driver, communiucation to a slave is possible.
+
+One error is however encounterd during dereg of the device, see below.
+
+dmesg from when this driver is used:
+```

+dmesg using newest Kvaser socketcan_kvaser_drivers patched and added can_change_state()
+
+Connecting leaf to usb:
+[Mar24 11:26] usb 1-2: new high-speed USB device number 11 using xhci_hcd
+[  +0.126349] usb 1-2: New USB device found, idVendor=0bfd, idProduct=0120, bcdDevice= 0.01
+[  +0.000003] usb 1-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0
+[  +0.000002] usb 1-2: Product: Kvaser Leaf Light v2
+[  +0.000002] usb 1-2: Manufacturer: Kvaser AB
+[  +0.034801] usbcore: registered new interface driver kvaser_usb
+
+Can intreface is now visible with ip addr:
+
+ip addr

+    link/can 
+
+
+And the interface is working!
+
+Disconnecting leaf from usb:
+[Mar24 10:31] usb 1-2: USB disconnect, device number 8

+
+Get the above error at disconnect of usb
