Prismatik not working with driver update wch.cn - Ports - 3.8.2023.2

Open terrainer opened this issue 2 years ago • 2 comments

Just a heads up for everyone.

Windows 11 updated my COM3 driver to wch.cn - Ports - 3.8.2023.2, causing Prismatik to be unable to control the LED strip I was using.

Everything is working again after going to Device Manager > Ports (COM & LPT) > USB-SERIAL CH340 properties > Driver > Roll Back Driver

Hope this helps anyone who is having trouble after recent updates.

I agree, when downgrading the driver to 3.5.2019.1 everything is back to normal. https://www.catalog.update.microsoft.com/Search.aspx?q=CH340 Thank you
