I don't believe so. As far as I can see, the USB port is the only power source.

Apparently it is powered exclusively from the USB port itself, not too certain on wattage however. There is a s/pdif out and in, and a 3.5mm line in (I use a red/white composite cable converter to play any console games). I believe the software that runs it is strictly PC, but I have no certainty that it will function in this manner.

I don't think it can,,because its a soundcard not a coonector..it'll work on operation system..I don't event try anyway..thank

I suspect that you could plug one of the USB cable into an external power source. The question is, "which one"! I would suggest trying the plug on the end to your computer first, then the 2nd plug, (the one with the short lead), to the power source. However, if this does not work, then swap the 2..... One of the plugs is for power only, (no data line in that one)..... However, when all else fails, add a cheap, 2 or 4 port "active" hub to your computer, then plug a couple of your other USB devices to the HUB.... This can cost less than $20.00 This wireless adapter works so well, adding a small hub still makes this adapter the ONLY way to go wireless!

I have powered a small usb drive. I think the key is that you might have to use a drive that is only usb powered, but I don't know entirely for sure. You could always get the cable and try it.

It's not a problem to power an external HD on this USB port. DVD? Sorry, not sure about that. Never tried.

I am not sure, sometimes the source is a in instead of a out, or vise versa, the USB should carry image signal, but if your going from a in to a in it will not work.. What I did is buy a transfer box that changed the the audio and video signal from optical digital in to analog rca out, to analog in..don't know if this helped you or not?

Technically, the answer is yes; it gains its power externally--it has no internal power source. However, in common parlance the answer the answer is no, since it gains its power through the usb and does not have a separate power cord or connection.

Yes, the optical digital input has to be connected to a digital source. TVs nowadays all have these outputs. Some older TVs also have them as well. You can use the analog stereo mini Jack to connect to computers through the headphone / speaker line out.

Hi Zachary ... Appears this is not what you want. [I am unclear if an Airport Express can be powered via USB and not its own power adapter.] This specifically is a USB-to-serial data cable with a built in UART chip. There can be very low levels of 3.3v or 5v generated (varies with various models) but that's not gonna drive a whole big device like Airport - more to drive one or two chips on a small board. This is designed for making your USB-equipped PC - desktop or laptop - look like it has a built-in COMn: serial port. FYI, "TTL" means transitor-to-transistor logic levels (meaning 5VDC), and Tx & Rx are the UART lines for transmitted & received serial data at logic level (not +/- 10+ VDC swing used by actual RS232 line levels).

The analog Co-axil port on my TV is not broken...the TV works just fine. I currently have an antenna and just need to boost the signal. The signal boost I purchased does not work, but is receiving power from the outlet, but the booster itself does not work. I know this because I tested the power cord send with the amplifier with a mutlimeter. I would prefer to have another amplifier sent, not an antenna and I do not want to convert to HDMI because my TV has no available HDMI ports left.

The USB is output only, not input. You can use that port for charging devices with an already charged battery. For instance, I charged my iPhone during a power outage. Pretty handy, but it doesn't work the other way.

Yes it is. I have both an optical input and a USB input and I am able to switch between the two. Occasionally, I have to switch it off to get the signal light, but that's only happened a couple of times. I cannot answer as to how it responds if you have all 3 inputs in, as to whether it only selects the one that is "on".

It is not listed on the device. wikipedia says "Powered USB is a proprietary extension that adds four additional pins supplying up to 6 A at either 5 V, 12 V, or 24 V." I have a 5V 2 Amp adapter whose connector is too small.Output of the cable reads 5 V. I had to check because I had not heard of 12 V or 24 V in conjunction to USB.

If your TV has a USB port, the antenna is powered by it. No other power source is needed.

You can plug a regular usb into it, and it comes with a micro usb cable attached. It should work universally as usb output is only 5v

There is an after-market power cable available that connects to a USB port. I have mine plugged into the port on my TV and the whole system is invisible from the front.

The red USB in this VGA to HDMI converter does not serve to access any data. I think it is used for some extra juice so that the VGA and audio signals are clear as they are converted into HDMI video and audio. You can plug the red USB cable into pretty much any USB port, but since the red USB cable is connected to a VGA and HDMI outputs, it might be hard to receive any information through the red USB cable. If your intention is to simply power the red USB cable through a service plug that's located on a TV, then, I don't see why the TV service port shouldn't be able to provide the necessary power. You might simply want to power the red USB through a wall adaptor - just get any phone charger with USB A output (just Google USB A image, you'll see what it is) and a USB extension cable, like here: http://www.amazon.com/AmazonBasics-A-Male-A-Female-Extension-Cable/dp/B001TH7GUU/ref=sr_1_1?ie=UTF8&qid=1409923057&sr=8-1&keywords=amazon+usb+extension which you can plug directly into the red USB. You can also plug the red USB directly into the phone wall-charger, but the red USB' cable length might be a problem.

Nope. It needs 5V 2000mA. TV USB ports are just mean for powering USB sticks. So it will not support the power rating required. Same is true for self powered USB drive of large size (1TB). They do not work on USB port. But you can connect them to a powered USB hub and connect that to TV. That should probably work.
