I'm new here, and was just wondering if you were serious about it being active. Wondering if the smiley face was actually in celebration.

AND for a power source, it never did fully charge my cell phone via the USB port. Maybe the voltage may be right but not the amperage? or V V?

USB ports have limited low power so devices that require lots need an external source. You can receive charging power but if you ever tried to use the USB port for a WiFi access point you will discover it rarely works. Bus card APs get far more power compared to the range of USB APs.
The Cisco USB port, as with other STBs, is typically used for firmware upgrades via cable or flash drive. Sony's devices like the PSP have this feature. My guess is that the port is for this purpose allowing AT&T to add services to the STB in the future (or fix some future security issue). That said, the USB port would connect to the voltage bus and the firmware chipset. A future use of the port for a HDD would require a new module or replacement STB.
