7) At the first Update Driver Software prompt, select “Browse my computer for driver software”. 8) At the second Update Driver Software prompt, select “Let me pick from a list of device drivers on my computer” 9) At the third Update Driver Software prompt, select “Prolific USB-to-Serial Comm Port Version: 3.2.0.0 7/31/2007”.
Most Creality Printers use a FTDI F232R USB to Serial adapter chip for them to use USB. If you have a V1.1.4 board you will want to use the CH340 Driver instead. If you are having issues communicating with your board try installing one of the drivers below.
Before connecting the Nano to your USB port: Open “ch341ser.exe” file and run it.The software extracts about 8 files. The software asks whether it can install the CH341SER.INF driver for the CH340 chip (Version, 3.3.2011.11). Click INSTALL A Windows message asks whether the driver has installed correctly.
When autocomplete results are available use up and down arrows to review and enter to select.

Microsoft-provided in-box driver (Usbser.sys) for your Communications and CDC Control device.

In Windows 10, the driver has been rewritten by using the Kernel-Mode Driver Framework that improves the overall stability of the driver.

Improved PnP and power management by the driver (such as, handling surprise removal).
Added power management features such as USB Selective Suspend.

In addition, UWP applications can now use the APIs provided by the new Windows.Devices.SerialCommunication namespace that allow apps to talk to these devices.

Usbser.sys installation

Load the Microsoft-provided in-box driver (Usbser.sys) for your Communications and CDC Control device.

Note

If you trying to install a USB device class driver included in Windows, you do not need to download the driver. They are installed automatically. If they are not installed automatically, contact the device manufacturer. For the list of USB device class driver included in Windows, see USB device class drivers included in Windows.

Windows 10

In Windows 10, a new INF, Usbser.inf, has been added to %Systemroot%Inf that loads Usbser.sys as the function device object (FDO) in the device stack. If your device belongs to the Communications and CDC Control device class, Usbser.sys is loaded automatically.You do not need to write your own INF to reference the driver. The driver is loaded based on a compatible ID match similar to other USB device class drivers included in Windows.

USBClass_02

USBClass_02&SubClass_02

If you want to load Usbser.sys automatically, set the class code to 02 and subclass code to 02 in the Device Descriptor. For more information, see USB communications device class. With this approach, you are not required to distribute INF files for your device because the system uses Usbser.inf.
If your device specifies class code 02 but a subclass code value other than 02, Usbser.sys does not load automatically. Pnp Manager tries to find a driver. If a suitable driver is not found, the device might not have a driver loaded. In this case, you might have to load your own driver or write an INF that references another in-box driver.
If your device specifies class and subclass codes to 02, and you want to load another driver instead of Usbser.sys, you have to write an INF that specifies the hardware ID of the device and the driver to install. For examples, look through the INF files included with sample drivers and find devices similar to your device. For information about INF sections, see Overview of INF Files.

Note

Microsoft encourages you to use in-box drivers whenever possible. On mobile editions of Windows, such as Windows 10 Mobile, only drivers that are part of the operating system are loaded. Unlike desktop editions, it is not possible to load a driver through an external driver package. With the new in-box INF, Usbser.sys is automatically loaded if a USB-to-serial device is detected on the mobile device.

Windows 8.1 and earlier versions

In Windows 8.1 and earlier versions of the operating system, Usbser.sys is not automatically loaded when a USB-to-serial device is attached to a computer. To load the driver, you need to write an INF that references the modem INF (mdmcpq.inf) by using the Include directive. The directive is required for instantiating the service, copying inbox binaries, and registering a device interface GUID that applications require to find the device and talk to it. That INF specifies 'Usbser' as a lower filter driver in a device stack.

The INF also needs to specify the device setup class as Modem to use mdmcpq.inf. Under the [Version] section of the INF, specify the Modem and the device class GUID. for details, see System-Supplied Device Setup Classes.

For more information, see this KB article.

Configure selective suspend for Usbser.sys

Starting in Windows 10, Usbser.sys supports USB Selective Suspend. It allows the attached USB-to-serial device to enter a low power state when not in use, while the system remains in the S0 state. When communication with the device resumes, the device can leave the Suspend state and resume Working state. The feature is disabled by default and can be enabled and configured by setting the IdleUsbSelectiveSuspendPolicy entry under this registry key:

To configure power management features of Usbser.sys, you can set IdleUsbSelectiveSuspendPolicy to:

'0x00000001': Enters selective suspend when idle, that is, when there are no active data transfers to or from the device.
'0x00000000': Enters selective suspend only when there are no open handles to the device.

That entry can be added in one of two ways:

Write an INF that references the install INF and add the registry entry in the HW.AddReg section.
Describe the registry entry in an extended properties OS feature descriptor. Add a custom property section that sets the bPropertyName field to a Unicode string, 'IdleUsbSelectiveSuspendPolicy' and wPropertyNameLength to 62 bytes. Set the bPropertyData field to '0x00000001' or '0x00000000'. The property values are stored as little-endian 32-bit integers.
For more information, see Microsoft OS Descriptors.

Develop Windows applications for a USB CDC device

If you install Usbser.sys for the USB CDC device, here are the application programming model options:

Starting in Windows 10, a Windows app can send requests to Usbser.sys by using the Windows.Devices.SerialCommunication namespace. It defines Windows Runtime classes that can use to communicate with a USB CDC device through a serial port or some abstraction of a serial port. The classes provide functionality to discover such serial device, read and write data, and control serial-specific properties for flow control, such as setting baud rate, signal states.
In Windows 8.1 and earlier versions, you can write a Windows desktop application that opens a virtual COM port and communicates with the device. For more information, see:

FTDI Driver Installation

Development boards such as the SparkFun RedBoard for Arduino and the Arduino Uno require special drivers or code that tells the computer how to interact with them. This guide is here to help you get this driver software installed as quickly as possible so you can get back to building circuits and learning about electronics!

These instructions apply to both the Arduino Uno, the Arduino Uno SMD, and the SparkFun RedBoard for Arduino.

Note: You should only have to complete this process one time. Once the correct drivers are installed, your board will be recognized by your computer every time you plug it in afterwards.

Note for Educators: You will most likely need to obtain administrative privileges from your network or IT administrator in order to install these drivers.

Scroll down to the corresponding section for whichever operating system (OS) you are using.

Windows

Plug the board into your computer. Windows will likely complain about the device not having the correct driver. It may attempt to find it. If you have never plugged in a similar device to your computer, it probably won't find a driver to use. Luckily, when you downloaded the Arduino IDE, it also came with all the necessary drivers.

To install the correct driver, open the Device Manger. This can be found be searching for 'device manager' in the start menu. Once Device Manager is open, you should see a device with a tiny yellow triangle and exclamation mark next to it.

If you plugged in a SparkFun RedBoard, it will look like the image on the left. Plugging in an Arduino Uno will result in the image on the right.

Right-click on the unknown device, and select Properties.

In the properties window, select Driver Details.

Select the Browse my computer for driver software option.

Navigate to the destination where you installed the Arduino IDE. On Windows, this will most likely be in your Program Files folder. Navigate to the drivers folder found inside the main Arduino folder. You can select the entire folder or the specific driver. needed Your path should look something like this but may vary:

Once the driver installation is complete, you should see the device reappear in the Device Manager window as a usable COM port. The number will vary depending on how many devices you have plugged into your computer. The RedBoard will appear as a USB Serial Port, as shown in the left image. The Uno will appear as an Arduino Uno, as shown in the right image.

In the Arduino IDE, you should see that same serial port available under Tools -> Port.

If you are experiencing problems, please see our in-depth instructions.

MacOS

Plug the board into your computer. Once plugged in, the operating system should recognize it as the appropriate device. In the Arduino IDE, click Tool -> Ports to ensure the device has been recognized. The SparkFun RedBoard will appear a cu.usbserial-XXXXXX device.

The Arduino Uno will appear as a cu.usbmodemXXXXXX device.

If you do not see an available serial port in the Arduino IDE after plugging in your board and waiting a moment, then you may need to install the drivers by hand. To do so, please see our in-depth instructions.
