4.1.1
Interface mode
The device is in Interface mode when connected to the PC via USB. If the Power
LED is showing a steady green light, the device is in Interface mode and working
correctly. When connected to the computer for the first time, the Power LED will
blink slowly in yellow until the driver is installed and the device has received a USB
configuration.
When in Interface mode, if the Power LED is yellow for an extended period,
something is wrong. Please see Table 4.
The power should never be removed when firmware update is in
progress.

4.1.2
CAN and LIN usage
Kvaser Hybrid CAN/LIN is ready to be operated as either a CAN or LIN interface
when connected to the PC without further configuration. You can use the same
CANlib and LINlib API calls as with other Kvaser interfaces, use CANlib for CAN
and LINlib for LIN related usage. Both libraries are included in the Kvaser CANlib
SDK, see Section 2.4, Additional software and documentation, on Page 6.
4.1.3
CAN interface mode
When Kvaser Hybrid CAN/LIN is used as a CAN interface, the traffic LED is used
as described in Table 5 on Page 12.
