MT development boards are shipped from the factory with a jumper header across pins 2 and 3 of J3, which powers the clock from the main power supply. Check that the header has not been dislodged or removed. However, if a different version of the TAP-Windows adapter is already installed, or if the Azure Sphere device is not connected to the first instance of the TAP-Windows adapter, the Azure Sphere tools may fail to connect to your device.

To determine whether the problem is related to the TAP adapter, first find out how many TAP adapters are installed on your PC, and then modify the installation if necessary. You should see only one TAP adapter, as in the screenshot:. In the dialog box, check Delete the driver software for this device, then click Uninstall. If you see only one or two, as in the following screenshot, you may have a problem with the FTDI driver:.

Unplug your development board from your PC and plug it back in again. Choose 'Search automatically for updated driver software. If the following error occurs after you attach an MT development board, you may have a USB error:. Windows has stopped this device because it has reported problems. Code 43 A USB port reset request failed. If the error occurred when the device was plugged into a USB hub, plug it into a port on the PC instead. If the problem recurs, plug the device into a powered USB hub.

In some cases, USB ports do not provide adequate power for the board, so a powered hub may solve the problem. If your PC can connect to the Azure Sphere device, but often drops the connection, you may have a conflict in the IP subnet.

Azure Sphere uses subnet If you have other software that uses the same subnet, either disable that software or limit the range of IP addresses that it uses. I would suggest you to check for the version of Windows you are using. To check the version of Windows installed on the system refer to the below link. Under Hardware and Sound, click Configure a device.

If the above step does not help us to diagnose the issue, uninstall the drivers for USB [Universal Serial bus] host controller and restart the computer.

Let Windows install the generic drivers and then see if it helps you to fix the issue. You can also refer to the link provided below for information on connecting the Dynex USB Universal Serial Bus to serial adapter with the system. Here are some troubleshooting steps for common installation and setup problems. Failure to connect to device Probably the most common problem is a failure to connect to the Azure Sphere device.

The following error messages may indicate a failed connection: An error occurred. It also has a couple of LEDs on board shown when comms is active - sometimes useful. Search for above text on ebay. There are bound to be others available if you can not see that exact one. Since RS voltage levels are generated it will allow operation over long cables. There are bound to be others available if you can not see that exact one..

To progress, next you need a terminal program running on your PC so that you can send data to, and receive data from the microcontroller. A suitable program is "Tera Term" which is a free. All you do is plug your chosen USB to serial interface into the USB port and connect to the development board and then start The terminal program. Then all you do is select the serial interface that has appeared as a result of plugging in the serial to USB interface and everything works the same as if you had a built in serial link.
