Windows 7: Long USB run from computer to TV

Long USB run from computer to TV

I'd like to set up a KB+M at my TV from the computer. I've got a wireless KB + M which work fine for non games. As soon as I boot a game at the TV the KB+M become virtually useless, as in, no response. I'd like to run a USB cable from the computer USB Hub to the TV room. I'm thinking the run would be about 20' +/- and terminate at a splitter or hub for a wired mouse and Orbweaver..

Will I have a problem with this length?

All I can say is you can try but that is pushing things way far for a performance device like a KB&M.
I run a 10' extension for a printer and with a std. usb cord it runs about 15' and that works for it.

16' feet is the upper limit for a passive USB cable (often, even that is too long). I have seen active cables as long as 32' and sometimes they can be daisy chained with another active cable or a shorter passive cable. Generally, the active cable has to be connected directly to the computer although it might work alright from a powered hub.

What about going from a powered hub to a powered hub?

I can't speak to that but maybe someone else can?

If you have to run long distances like that I would at least use a powered hub somewhere in the middle of the run.

And note that some powered devices don't tolerate long USB cable runs. I know WD recommends a short distance when using their passport drives which does require power from the USB to power the drive.

You can check these articles out:

- How Long Can You Run a USB Cable? | eHow

My two cents.

According to the eHow article, I can chain hubs. I remeasured and I may be able to get away with a single hub. I'm 7' from the wall and about 3' from the computer to the wall so that makes about 10'. I've already got the mouse. When I get the Orbweaver I'll try it out for the distance.

I think all of this is going to annoy my wife to no end. She kinda likes the bigger TV but thinks it doesn't fit the "decor," not that we have any. Now, I'm cluttering up my side table with all these remotes, mice and other doo-dahs. Actually had to put down a large plywood plank to hold everything.

But hey, it's all fun.

Check out the specs on this active USB cable. Note that it can be had in three different lengths. If one is too short and the next is too long, an extension can be added. As long as the source is the computer itself or a powered hub, the cable and possible extension should be all that is needed. There should be no need for daisy chaining hubs.
