Do you have another machine you could test the cable on?

ok unplug the cable, shutdown the computer, wait a few minutes (this may help reset the USB port if a polyfuse blew), reboot the computer
then plug the cable in, and in terminal check & paste the output of

ls /dev/cu*

The Mac reboot did the trick with the cable - I can now see and upload to the 8266. However, I am back to my original problem - the non-responding 8266. I was able to upload the Blink code from the above page successfully, but it doesn't blink - the red LED is lit continuously - nothing is blinking.

Forgot about having to reset to get it out of bootloader mode. It blinked so I went onto the second test - bringing up WiFi. After uploading and resetting, I watched the serial monitor. I got a message that it was connecting to my SSID and then an endless row of periods put out by this section of code

while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");

The SSID and password are correct

ok sounds like your hardware is running now - check out tutorials online on progamming the ESP, if you can program it, its likely just a software bug in your sketch :)

I used the example code from your website. The board is non-functional as a WiFi device, It needs to be replaced≥

try an example where you create an access point AND also try an example where you scan wifi AP's
