Hello,

I have been trying to install the CYUSB3Kit-003 EZUSB FX3 USB Serial driver in order to create a COM (serial) port in Windows, but I have not had success installing the driver.

After successfully installing the driver for FX3 via the SDK, I downloaded and installed the USBSerialSDKSetup.exe from https://www.cypress.com/documentation/software-and-drivers/usb-serial-software-development-kit  and attempted to install on a Windows 10 machine.

I ran the setup and then located the driver file, cyUSB3.inf to manually install it via Windows Device Manager, and I received a message that my driver did not successfully install, error code 31.  I tried uninstalling and reinstalling it with no luck. I also tried the CypressSerial.inf driver. deviceNotWorkingProperly.pngdriverError.pngI tried the same process on a Windows 7 machine and I had the same issues (Please, see images below).  The USB serial device driver "installs" but will not work properly because Windows cannot load it. So it shows up in the Device Manager list with a warning next to its name.

The FX3 SDK installed successfully, is there a working driver for the USB Serial function as well? The Cypress drivers don't load properly for Windows 10 or Windows 7.  There are also Cypress USB serial drivers that Windows includes under the Ports and LPT device, but they also do not load properly.

Is there a method that I am missing here? I'd like to get this driver installed so that I can communicate with it via the serial port.

Thanks

Hello,

Please try the below methods:

1.  Restart the computer and then plug in the device.

2. Automatic Driver Update: Please make sure that the PC is connected to internet.

3. You can bind the device to Microsoft driver by following the steps mentioned in this KBA: Binding a USB-Serial Device to a Microsoft® CDC Driver – KBA91366

Please let me know if any of the three methods worked.

Thanks,

Yatheesh

Thank you for responding, I tried the above methods, rebooting and plugging the device back in (USB serial port end) worked.  Thank you very much.YatheeshK_36
