I'm using a USB CAN or LIN device and when I plug it into my computer the LED next to the network type (either CAN or LIN) isn't lit up. What does this mean? Is my USB device broken? Also, what does the color of the USB LED mean?
The USB CAN and LIN have a few lights on the front of the housing. You should notice a USB LED on your device that lights up when you plug it in. The USB LED will be orange if you have a USB high-speed connection (USB 2.0) and green if you have a USB full-speed connection (USB 1.0). The CAN or LIN LED does not indicate the functionality of the device. It indicates when the device is sending data to the bus or receiving data from the bus.
