USB connection to HIL Lost / Unable to detect HIL
Last Updated 4 years ago

In case Typhoon HIL Control Center cannot detect a HIL device via USB, this problem can be either traced to hardware, USB driver, or USB power management scheme. Windows updates are known to delete drivers for various devices, HIL included.

First follow these instructions to eliminate any hardware problems that might be causing this:

  1. Move USB connection from front to back. Usually back USB ports are more reliable because they are directly connected to the motherboard.
  2. Use HUB with its own power supply.
  3. Use originally supplied USB cable, alternatively the cable should have EMI filters on both ends.
  4. Check if UART port is in loopback connection. If it is, disconnect it and then restart the device.
If the issue still persists first check if the HIL device is visible in the Device Manager. If your device is powered on and successfully detected by Device Manager you should see it in the list under libusbK Usb Devices:

In this case do the following:

  1. Execute Method 2
  2. Restart your PC
  3. Restart your HIL
