What is the purpose of the second usb cord?

It provides extra power if needed to run DVD drive. Mine ran fine without need for second cord.

Don't know. They are there to recharge phones, tablets, or whatever else you need charged. Haven't had any problems with the USB ports.

The cable is not to have two printers work with on PC. Rather to connect ONE hard drive, or other device which needs more power to operate. The second plug is for additional power to ONE device..

There is a provided connection USB cable. It is accessed via a hidden compartment underneath. The cable connected...not separate

It doesn't really matter what usb it's plugged into. Its mainly used for charging and data transfer where all the video is through the hdmi connection.

There is only one cable with mine. There is no USB cable, only a socket with one of those sort of oddly shaped plug usually on the other end of a USB cable. I believe its called a mini B jon

This device provides a second plug for any purpose that you wish. I suppose one could also use two of them if you have a second device or with a Y splitter for that purpose such as the Cables Unlimited PWR-PSLIB-2 Outlet Xtender Power Cord Splitter also available from Amazon.

I'm sorry, but I have no clue. The USB plug worked fine for me. Perhaps it is defective.

The usb is the charger and also used to download music. Very simple little thing but holds a wealth of music. Very small. I lost mine twice. Finally bought a second one so I would know where one of them was. LOL

No. The extra USB connection is to provide more power to one device than a single connection allows. Some hard drives need more power and that's what this cable is for.

No. The sole purpose of the USB port is to provide a power source for other portable devices.

It is a cable to add a second internal hard drive. I used it for my HP DV7 laptop, which had a second bay but was not wired for a second drive. This cable runs from the motherboard to the additional internal hard drive... if your computer has a place for one.

The usb is for power. The hdmi is on the opposite end from the audio video connections.

It's a USB connection for both. Neat too because they aren't the typical black colored cord for electronics; they're more of a tan color.

It has the second USB connector if additional power is needed but I am running it using just the main USB connector plugged in....No issues to speak of.
