I am unable to get the USB driver working with KFLOP in Windows 10. When I connect KFLOP to a USB port after uninstalling the non functioning driver, Windows tells me "we're setting up KFLOP motion controller" and then, after a second or two, "KFLOP motion controller is set up and ready to go". When I then go to the Device Manager, I see the KFLOP motion controller under "other devices" with a yellow caution sign.
When I click on properties I am told "drivers for this device are not installed (code 28)". Going through the driver update routine does not work either.
I also disabled the Windows driver signature enforcement to no avail. Clicking on Dynoport.inf and then "install" makes no difference.
My Windows has the latest updates. I have spent an afternoon on this and can't think of anything else to do.

Hi Bernie,

What Version of KMotion are you using?

Are you following all the steps toward the end of this article to remove/install the Drivers?

Hi Tom,
Yes, I am following those instructions. This may not have anything to do with my driver problems: I just received the board 2 days ago. Does it have the latest firmware on it? I downloaded KMotion just about two weeks ago. How do I find out what version I have?

Hi Bernie,

Recent boards are shipped with Latest Released Version 4.34.

The Firmware Version in KFLOP shouldn't have anything to do with the Software/Driver Versions on the PC.

To check the Software Version loaded on the PC run KMotion.exe then Help | About

To check the Firmware Version in KFLOP enter "Version" on the Console Screen (obviously the Windows/USB Drivers must be properly installed for this to work).

You might post Screen Shots of each Step you are doing so we can verify how you are removing/updating the Drivers and what messages you receive from Windows.

Hi Tom,
Here are some screen shots. I then click uninstall, unplug the USB and plug it back in.
After KFLOP stops blinking windows tells me "that it is setting up the KFLOP Motion Controller,
and then, " device is ready - KFLOP Motion Controller is set up and ready to go"
Then it doesn't work.
Sorry to see you working on weekends.

Hi Bernie,

What Version of KMotion is installed?

You will need to Update Drivers and direct Windows to use our our Drivers in the "USB Driver" folder.

Do you have administrator privileges?

Please post screen shots of your Update Driver process.

Thanks Tom,
My KMotion is version 4.34 and I do have administrator privileges.

Hi Bernie,

Please post screen shots of your Update Driver process.

Hi Tom,
Here are some screen shots. When I click on the i386 folder no .inf file becomes visible.
When I use file explorer to look at the contents of the i386 folder I do see dynoport.inf.
When I right-click on dynoport.inf and then on "install", it gets installed but does't work.
You just gota love windows.
Thanks
Bernie

Hi Bernie,

Please select the “USB Driver” folder not the “USB Driver\i386” directory. You may need to check include subfolders. I386 is for 32-bit Windows. Is your OS 32-bits or 64-Bits?
