Do you have to connect both the HDMI and the USB in order for both the video and touch to work?

Yes, USB is required for touch to work. HDMI/DVI/VGA is required for video. So you do need both to have both working.

The USB connection must be made for the touch screen to work. Video can be via HDMI or DVI.

Yes, the HDMI transmits video and the USB transmits touch. If you don't care about touch, you don't need to attach the USB cable.

No, most newer computers have an HDMI interface, and would use a simpler HDMI to HDMI cable. This is specifically designed for certain phones and tablets that implement the MHL interface, which provides USB and HDMI functionality in one connector. Note that the USB connector in this cable is there to provide power for the HDMI feature.

You need an HDMI cable for sound and picture and there should have been a USB cable that came with it to hook it up to your computer for the touch screen functionality.

You need to plug in the USB cable as well. HDMI only does sound and video, the USB cable is for the hub and touchscreen.

Yes. When you press the switch button it switches video/audio/USB between two inputs. If you have nothing plugged in for video/audio it still works. Note that USB does have to be plugged in to power the device.

The DVI to HDMI cable is responsible for the display. In order for the touch function to work, you have to connect the USB cable to your system.

You can connect it via HDMI or DVI, there is no USB video source unless you have 2 monitors.

No on the HDMI connector, and I bought a micro adapter to support a usb. Hope that helps.

No, a HDMI cable can only be used to Display video onto another screen with HIDMI. If you want to transfer data onto your phone or tablet you will need an micro USB cabe.

To further my non answer: During the limited time the unit was operational, I did not use the USB input, only HDMI. It seemed to have no problem with that input. Now I know why it was a "limited" edition.

Robert, it's a mystery to me. I own the TV and have tried to connect other devices with the USB port, and can't get it to show on the screen.

Not this unit. 1 HDMI port, and a Micro SD. It does come with an adapter that terminates in USB female port, however I could not get it to work.

You can connect to an external HDMI monitor but you cannot (as far as I know) use an external touch interface with it.

So far as I know, both devices use USB 2.0 cables with a micro-B connector. The cables you asked about are HDMI cables; an entirely different technology.
