Does the device require 2 USB ports to operate?

No just one. It is not perfect. The CD or DVD must be perfect to play or record.

Yes, one is for data, the other is for power. Though it may be possible to use a USB charger for this connection. I have used the unit with a tablet by using a multi-port adapter.

I haven't tried that; I use the USB receiver that it came with. I have a USB port extender on my laptop since it does take 2 ports.

Oddly, no. But you will need two USB ports near each other for the device to function. That's right - the custom cable that comes with the unit has two USB plugs for your laptop to draw extra USB power for operation. Weird, but it works.

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.

Yes, it has two usb cables. I always plug them both in to my usb ports on my laptop. One I believe is the power, and the other the regular usb connection.

No it does not. This is another reason I love this device. It is slim enough to use it in a wall plug and use the other plugin at the same time. Or you can use both wallplugs AND BOTH USB at the same time.

No, just two USB cords so that an additional port can be used to power it. This mostly applies to older computers and laptops where the usb ports did not supply as much power as USB 2.0 and USB 3.0

It has one USB port on the keyboard itself; also it takes two USB ports for the keyboard itself.

Yes. It however will only operate at the 2.0 speed that the USB port is designed to handle.

This is what this device is designed for - 2 USB ports give extra power to 1 device.

There's only one port. I doubt that you can connect 2 even with additional cables

There is just the 2 usb ports in the front and 2 in the back. They are not 2.0

No. It has a button to switch between ports. However, it does automatically switch to whichever port device is powered. Of course, if two or more are powered you will have to manually select the one you want.

It uses only 1 - USB port. I have also used a USB 3 hub and it worked that way as well.

No it does not have a USB port. And it requires two USB ports available on the computer.

No there are not any USB ports to plug it in with since it draws its power from the device it's self

No it does not. It comes with a dual-head usb 2.0 cord. If you have a usb 3.0 port you only need to connect one of the usb heads. There is a connection for an ac/dc connection on the back of the device.
