It would actually require about 50 feet of cable, since it would have to go through the ceiling.

Radio? I have a Logitech wireless keyboard and mouse that weren’t all that expensive.

Why do you want to do such a thing? How are you going to read the monitor if you’re 40 feet away?

Most of the wireless keyboard/mouse units I have seen advertise a range of about 10 feet. You may get lucky and have it work that far away, or you may be able to find some way to boost the range.

I have to ask, along with the others, “Why?”

My guess is to control iTunes or some other music program, I use my Logitech keyboard in the living room to control songs. The comp is in the dining room, but the couch is more comfy to listen on.

Wireless keyboard/mouse combo, with USB.

Add a USB extension cord.

Run cord from PC through ceiling to near location.

Install receiver unit for keyboard/mouse at location in convenient spot.

Use keyboard as normal.

If you want to control a program like iTunes or other media player, look into a remote control that works with your video card.

Well, the monitor is 40 feet away, too; I just didn’t need help with that.

I have heard of USB extension cables, but [this site](http://www.usb.org/developers/usbfaq/#cab3) seems to be saying (if I understand them) not to use them, and to use Ethernet or serial instead.

Typically, an [KVM Extender](http://www.rose.com/datasheet/crystalview.pdf) video is used, which will also include the video. This particular one goes over cat 5 (twisted pair) cable.

You also might want to look into USB-over-CAT5 products like [this one](http://www.gefen.com/kvm/product.jsp?prod_id=2181). That way you can add a mouse or other peripheral at the far end easily without having to run more wires. Just use a USB hub.

Logitech makes a **bluetooth** keyboard(expensive! ~100$). My friend has used it through walls and such. 40 feet seems in reason.

Thanks all. I think **ParentalAdvisory** has found the cheapest solution. A Bluetooth keyboard may work, but does Linux support Bluetooth HIDs?

Hold on a minute. **ParentalAdvisory** , your site also sells a 50 foot PS2 cable ([CC321-50S](http://www.mc3llc.com/prodimages/CC321-S_LR.jpg)). Why can’t I use that?

Now I’m confused. I really thought that cables like USB, PS2, and DIN5 couldn’t go more than a few feet, which is why I started this thread. Would a 50 foot cable require a booster or something?

PS/2 cables may be extended quite a length (as I found out when I ordered what I believed to be 1.5 metre keyboard extension cables, and they turned out to be 15 metre (they were listed as 15m, but they were cheaper than the 1.8m cables - I figured there was just a missing decimal point).

So I’ve used PS/2 mice and keyboards across 15 metres of extention cable (that’s ~45 feet). I can’t imagine another 5 feet would kill it - I’ll try plugging two together in series tomorrow.  
USB has a rather short limit (5m or so), but there are various ways to extend it.

If your objective is to control a computer or monitor from afar using a keyboard, there are ways to do that without attaching a keyboard directly to the computer. pcAnywhere comes to mind.
