11.Nov.2018 Update
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.
These devices can also interface to a host using the direct access driver. These drivers are static examples detailed in Application Note 197: The Serial Communications Guide for the CP210x. The CP210x Manufacturing DLL and Runtime DLL have been updated and must be used with v 6.0 and later of the CP210x Windows VCP Driver. Download Award Silicon Labs Dual CP2105 USB to UART Bridge: Enhanced COM Port other device drivers or install DriverPack Solution software for driver update. The Silicon Labs driver is USB to serial port converter v10.1.9;. Earlier versions do not work as well. This is very similar to the FTDI chip driver which is widely used for radio interfaces. However, Icom America has chosen use the chip from SL instead. The computer I am using is an HP Z2 G4 workstation. Aeotec support says 'The Z-Stick firmware can be found in the software you are using to interface with it.' , which I figure means InControl. I've looked at controller properties in the console window, nothing there, nothing else seems to lead me to a firmware version number. Windows 7 x64 3.1.0.0 If you know the download link for the latest driver version for your operating system, please submit it to help other users. USB ANT USBXpress Device is developed by Silicon Labs and is used by 289 users on Drivers Informer.
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.
