cDAQ-9178 driver specific?
My Windows 11 device manager does not seem to have a driver for cDAQ-9178. I can plug in a USB-6009 to my laptop and it is recognized and all works fine. I can plug the cDAQ-9178 into another Windows 11 machine and it works fine. Does a specific driver exist for the cDAQ-9178 chassis? More on forums.ni.com

Hi Default_227,

I'm Rodrigo and I will help you.

This same information can be found on the device manufacturer's website, so the device is really not compatible with Windows 11. Now you have 2 options:

Downgrade to Windows 10 to use the device

or

Use another device that is compatible with Windows 11.

http://www.prolific.com.tw/US/ShowProduct.aspx?...

In the website you can see the versions that are compatible with Windows 11.
