Is there a way to add more usb ports to an HDTV? Samsung?

I have one USB port and I realize there are HDMI switchers. Can you add a port multiplier (like on a PC) on an HDTV? Does it need to be a powered one (ac adapter)?

Just wondering even though I do not know of a use for it yet..

Thanks
Peter

Yes, you need an HDMI switch.

Are you in the UK?

Well, it really depends on what the USB port does on the TV.

In my case, the USB port is just for diagnostics. It doesn't let you connect anything.

Even if you can connect things like a thumb drive to watch content, the TV may not have the necessary drivers to sort out a hub. Further, it may only have provisions to control one device at a time. For example, my Roku has one designation for "USB Drive". It's one channel only.

It would be like trying to run two devices into one input on your stereo. The stereo only is meant to see one device per input at a time.

The reason an HDMI splitter works is that it's toggling between devices and sending only one at a time to the input. USB hubs send everything to a single port all at once. A computer can sort it out because it can assign ID's to each one individually (known as IRQs). Most multimedia devices don't have that capacity. They control one device at a time on one port.

As I known, there are some gadgets can switch your USB port to HDMI port so that you can use a USB Hub to hold HDMI and USB both. And you can just get a USB Hub with ac adapter.

this is done often, with no damage. In fact, audio mixers are designed to do just this.

No, splitters don't switch anything. They send the same thing to both outputs.

No, this is not possible on an arbitrated bus.

No, device ID's are not IRQ's
