I have 2 Yaesu radio transceivers that are each connected to a separate HP Windows x64 computer. The 1st radio uses a separate device containing CP2105 drivers to allow CAT control of the radio, by the computer. This system worked fine until the radios CAT feature crashed (has since been repaired). Shortly after this, Windows came out with an update which was downloaded to each computer. While waiting for repairs to the 1st radio, I tried to download CP2105 drivers to the 2nd computer. The process advised that the drivers downloaded successfully, but they could not be located on the computer. Checked with Yaesu USA - they have no knowledge of this problem, but have sent a request to Japan for clarification. After repair, the 1st radio was again connected to its computer, but the CAT control no longer works. I uninstalled the drivers and installed the newest version - the drivers supposedly install but cannot be located. It appears my problem might be related to the Windows update as I have an HP notebook computer with an older version of Windows 10 and an older version of the drivers - this system still works. Has anyone else experienced this problem and if so, was the problem resolved?

Mark Enstone - SiLabs employee posted (March 26, 2019) on a separate case that - Reproduced, resolved, will release VCP v10.1.7 before end of the month. I have been working with Microsoft for the past week as the drivers on both my HP desktops disappeared when Windows 10 updated to 1809. The tech was not able to download these new drivers as the Installation Wizard provided the following message - The device driver installation wizard was unable to find any drivers designed for your machine. Check with vendor or your site administrator to ensure you have the correct program. I will put in a request to Yaesu for their input and keep this thread advised.

Still issues here?
VCP v10.1.7 (and later as subsequent releases are released) is available from Windows Update. (Go to Device Manager, select the device, select "update driver", select "search online").
Windows logs install-related activity -- including errors if they should occur -- in C:\Windows\INF\setupapi.dev.log. The timestamped log entries in that text file are usually the first level of self-support for install issues.

you could download driver here to see if it works.
Microsoft had me reinstall Windows 10. When we tried to download the drivers, the installation wizard then advised that the drivers had been successfully installed - but windows couldn't find them. I used USB View and Installed Drivers List, but the drivers were not located on my computer. Microsoft advised their software was working properly and that the fault is with the Yaesu radios - they closed their file and advised me to contact Yaesu. This is odd as the radios communicate with their respective computers under the Yaesu proprietary software. This would indicate that the cables, CAT connector and CAT commands are all working properly. As they were before the Windows upgrade. While I am not satisfied with the results, Microsoft spent a considerable amount of time trying to fix my problem, and I very much appreciate their efforts. If anyone has additional information or suggestions, it would be much appreciated.
