Review on DTECH USB to TTL Serial Adapter Cable 4 Pin 0.1 inch TX RX Signal with PL2303 Prolific Chip (6ft, Black): Windows 10 8 7 XP Vista Compatible by Johnathan Rothstein

Firmware installation failed. After numerous unsuccessful attempts to re-flash my router, I concluded that the green and white wires on my cable were reversed. I'm not sure if this is related to the cable I received or if it's a general issue. I'm just glad the power cable wasn't swapped, as I've been told that accidentally plugging it into the internal pin header is enough to damage the chipset. It's not a bad product for the price, but checking the output before plugging it into a router that costs several hundred dollars can be a good way to protect yourself from damage to what you're trying to fix.
