### ⭐⭐⭐⭐⭐ Good for Raspberry Pi devices

### ⭐⭐⭐⭐⭐ Good tty
*by C***M on February 10, 2026*

### ⭐⭐⭐⭐⭐ Worked great - Genuine PL2303GC & Windows 11
*by M***N on June 28, 2024*

Some reviews of this product complained about this DTech USB to TTL Serial cable not working with Windows 11 and/or getting a counterfeit device. I can't really verify whether mine was counterfeit but it showed up as a "Prolific PL2303GC USB Serial COM Port" in Device Manager on Windows 11 immediately, without having to hunt for drivers. I configured Putty to connect via serial, keyed in the COM Port that Device Manager defined the adapter as, connected the ground/TX/RX leads to the appropriate place on the Linksys EA6350v2's board, and gave the router power. Everything worked perfectly and allowed me to do the necessary things over serial to flash FreshTomato onto the router's flash memory. Included with the cable was a small pamphlet serving as documentation as well as a pinout/schematic of what's inside the slightly oversized USB connector.
