Question
I created a custom CP210x driver, but now Windows 7 won't let me install an uncertified driver. How do I install my driver on Windows 7 for testing purposes?
Answer
It's possible to install a customized, uncertified CP210x driver in Windows 7 by using the 'Disable Driver Signing' option. There are two ways to do this:
Note: These options are for testing purposes only, and the driver should be WHQL certified before being released. Please see the 'WHQL Testing' article in the Related Articles section or contact technical support for more information.
1) When rebooting the computer, press F8 (make sure the function keys are enabled if the keyboard has an 'F Lock' key) after the initial BIOS screen to access the boot options. Select the 'Disable Driver Signing' mode.
2) Within Windows 7, go to the Start Menu and type 'cmd.exe' in the Search Bar (do not press Enter). Right click on cmd.exe and choose Run as Administrator.
If User Account Control is enabled, click Yes. When the Command Shell is open, copy and paste (right-click and select Paste) the following:
bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS bcdedit.exe -set TESTSIGNING ON
The statement 'The operation completed successfully.' should appear, as shown.
After restarting the PC, driver signing will be disabled and the uncertified driver can be installed.
To re-enable driver signing, open the Command Shell in Administrator mode and copy and paste (right-click and select Paste) the following:
bcdedit.exe -set loadoptions ENABLE_INTEGRITY_CHECKS bcdedit.exe -set TESTSIGNING OFF
Driver Signing will then be enabled after a restart.
I have a problem installing CP210xVCPInstaller_x64.exe on Windows 7 under VMware on a macOS 10.12 iMac. To be more specific the Silicon Labs CP210xVCPInstaller_x64.exe does its thing and has the green check mark saying drivers were successfully installed on this compuer; however, there is nothing there when I go to the Device Manager. The Device Manager only shows
Ports (COM & LPT)
Communications Port (COM1)
What is even more strange is VMware Fusion says:
"The connection for the USB device 'Cyganl Integreated CP2012 UART Bridge Controller' was unsuccessful. Driver error."
I am a macOS user and could use some help as I am trying to use Kenwood Software to control the TS-590SG Ham Radio and the Kenwood software can only find COM1 - the virtural port is MIA
