As an example, "Slow Waver (Green/Yellow)" means that the LED is slowly blinking
by alternating between green and yellow.
The Kvaser Hybrid Pro 2xCAN/LIN has five LEDs as shown in Figure 4 on
Page 10. Their functions are shown in Table 4 on Page 12.

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 5.
The power should never be removed when firmware update is in
progress.
