30-4900 USB data wiring reversed

While trying to extend the USB connector for the 30-4900 Wideband Failsafe Gauge, I (painfully) discovered that AEM uses a USB connector with reversed data lines. I've never seen anything like that before, and there certainly is no apparent good reason for the reversal. I ordered a replacement wiring harness from AEM, and it also has reversed data lines. So in other words, when you extend the line, you will connect red-to-red, black-to-black, white-to-green, and green-to-white. I e-mailed AEM Tech for an explanation, and shockingly never got a response. I'm just curious if anyone else has had any experience with this?
