To troubleshoot a connectivity issue please try the following:

1. Ensure the cable is secure on the device and computer. Disconnect and reconnect the device.
2. If still not connecting and the cable is secure press the rest on the back of the device while connected to the computer.
3. If a reset does not work then disconnect the device from the computer, wait at least 10 seconds and try another USB port on the computer.
4. If another USB port does not resolve the issue disconnect the device, restart your computer, then connect the device.
5. If all the above fails you can Reinstall the Device Driver. Navigate to the Device Manager on your computer. Please note this will vary based on the operating system you are using. Once at the Device Manager screen locate Universal Serial Bus Controllers. Click the arrow/triangle to the left of the Universal Serial Bus Controllers to expand the drop down list. If the device driver is the issue one of the items listed will say Unknown Device. Right click on Unknown Device and select uninstall. Once the uninstall has been completed, restart your computer with the device still connected.
