This device is 'plug-n-play' and the drivers should automatically install to an Internet connected PC. Should your network block automated driver installs or the PC not be connected, the drivers may be downloaded from: MD-CC40x-000 Drivers (Silicon Labs CP210x USB to UART Bridge VCP) Note: This link will open in a new browser tab/window. The latest version Silicon labs driver cp210x USB to UART Bridge driver does not work (will not install) on Windows 10 build 1903. The older driver (6.7.4.261) installs and works fine on the same machine running Windows 10 build 1803. I am trying to communicate with an ESP32 development board that has Sil Labs USB to Serial chip. Cables with FTDI chipset (FT232R) will automatically download the correct driver when inserted into the USB port. WCH chipset Drivers for the WCH chipset (CH340/341) should also download automatically. If not, the driver and procedure can be found at this Link. SiLabs chipset Drivers for the Silicon Labs chipset (CP210x) should also download.
I have lost track of how many updates Microsoft has released since I first penned this article a few years ago. Working to troubleshoot an issue in an online forum I was pleased to find Silicon Labs has continued to release updated drivers.
Reviewing the release notes also available at the link below the latest drivers are certified with later versions of Windows 10.
The version on the Yaesu website is several years old.
DriverVer=03/28/2016,6.7.3.350
Current version available from Silicon Labs

DriverVer = 05/23/2018,10.1.3.2130
Install was easy it updated the existing driver install.
I am running Windows 10 Pro 64 Bit and am able to run the latest version of PCC downloaded from the Yaesu website without any special settings. Ham Radio Deluxe also works just fine with the updated driver.
With all of the security issues folks are having with Windows as Microsoft hardens the operating system. I would recommend following the Microsoft broad recommendation of keeping drivers updated.

I received an email from Ed Ve7ED raising awareness to a new USB serial driver from Silicon Labs, this is the chip which Yaesu uses in the FTDX3000 and I suspect other serial to USB radios and cables. Note if you are using Linux or OSX drivers for those platforms are also available. I have installed the 64Bit driver on my Windows 10 system and no runs, drips or errors.
Also worth noting drivers are available for OSX, Linux and Android if you are for example using FLDigi on those platforms.
