Hello Marc,
I uninstalled the driver and now :
- I don't have the leaf in /dev/ when I plug it, which is a good thing
- I have those modules running :
can_raw 17159 0
can 45043 1 can_raw
kvaser_usb 22385 0
can_dev 21659 1 kvaser_usb
- ifconfig -a shows the CAN :
can0 Link encap:UNSPEC HWaddr 00-00-00-00-00-00-00-00-00-00-00-00-00-
00-00-00
NOARP MTU:16 Metric:1
RX packets:0 errors:0 dropped:0 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:10
RX bytes:0 (0.0 B) TX bytes:0 (0.0 B)
- My kernel log shows :
usb 1-3: new high-speed USB device number 4 using xhci_hcd
[ 1393.767114] usb 1-3: New USB device found, idVendor=0bfd, idProduct=0120
[ 1393.767124] usb 1-3: New USB device strings: Mfr=0, Product=2,
SerialNumber=0
[ 1393.767128] usb 1-3: Product: Kvaser Leaf Light HS
[ 1393.815801] CAN device driver interface
[ 1393.857896] usbcore: registered new interface driver kvaser_usb
- When I try to run the example from http://en.wikipedia.org/wiki/SocketCAN I get this error :
vcan0 at index 1866752400
Error in socket bind: No such device
Thanks a lot for helping me.
