Why is my adapter not recognized on Windows 11?

Works flawlessly with my legacy CNC machine

I bought this adapter to connect my modern laptop to an old CNC machine that only has a serial port. Installation was a breeze on Windows 10 — plugged it in, installed the driver from the Plugable website, and it worked immediately. The chipset is reliable and I've had no connection drops even after hours of use. Highly recommend for anyone needing a solid USB-to-serial solution.

Works but driver installation is a bit tricky

The adapter works, but I had to manually download the driver from Plugable's site because Windows didn't automatically find it. Also, the driver signature caused a small hiccup on my older PC. Once set up, it functions as expected. Decent for the price, but be prepared to fiddle a bit if you're not tech-savvy.

Good for my network switch setup

I needed to configure a Cisco switch via console cable, and this adapter did the job. Just plug and play on my Windows 11 laptop, no extra software needed. The cable length is decent and the build feels solid. Only minor gripe is that the driver didn't automatically install on a friend's Win 7 machine, but we solved it by downloading from the site. Overall, great value.
