This series of patches offers the user the possibility to access in read/write mode a flashed numerical value for each channel of a PEAK-System USB - CAN/CANFD interface, through the sysfs interface, under the tree /sys/class/net/canX and the new entry "dev_num" of the newly created group "peak_usb". Thus the command : $ echo /sys/class/net/can0/peak_usb/dev_num will display the value stored in the internal memory, for the first channel of the PEAK-System device.
