So, download the FT232r USB UART driver from the given download link, just tap on the download button and get the driver. You will get an FT232r USB UART driver installed on the computer to connect the FT23R device to the computer to manage the stuff. So, make the driver updated direct from the computer, and install the driver easily. You need to disconnect the internet connection, disconnect the USB cable from your PC to KMX1 or KMX2Ī new yellow flag will be there, you need to update the driver directly from the computer.ĭo not go with the update the driver from the internet, as it takes you to the internet and you will end at the closed end.Uninstall the USB Serial Converter, and uninstall it directly from the computer.You need to confirm uninstall the driver, as it is important you need to uninstall the driver.

And tap on the uninstall button, you will be asked twice either you want to get the driver uninstalled.Any suggestion on a solution would be greatly appreciated. The only thing that I know of that's changed since I was successful early this year are the numerous Win 7 upgrades. When I run the FTDI executable installation file it runs and I get two green check marks and a "Ready to use" status but still nothing works and the Hardware Manager still says that the drivers are not installed (Code 28). I've downloaded the latest VCP drivers from FTDI to no avail.

When I try to update the driver I get a message saying that Windows can't find the driver for this device. Device Manager shows the FT232R USB UART device under the heading of Other Devices but the properties for this device says the drivers aren't installed. When I connect it, it tries to load the driver(s) but I get an error window saying "Device driver software was not successfully installed". Now I'm unable to communicate with the Nano. I successfully installed Arduino SW and developed sketches which I was able to load and execute early this year.
