| Dec 13, 2011 at 0:33 | comment | added | André Paramés | @Tim: are the devices networked? Because you could install a VNC server in each one (there are VNC servers for Android too) and then a single PC with all the client windows. Then you could use e.g. AutoHotKey to multiplex a single keypress to all the VNC windows. It's hacky, but it should work. | |
| Dec 12, 2011 at 23:44 | comment | added | Chris Stratton | I don't think this exists off the shelf, unless you are willing to use a software solution. It would be fairly practical to build by connecting a number of usb-slave-enabled micro-controllers (one per PC) to a usb-host-enabled one (for the keyboard) using their serial ports; if you want to look into building that, then it would be appropriate to ask such a question back on electronics.stackexchange. | |
| Dec 12, 2011 at 22:20 | comment | added | FoamyGuy | The keypresses from the keyboard are being used to trigger specific things to happen within software that I've written. Using the keyboard as a trigger like this is useful because one of the devices is an Android tablet which is not going to support any sort of triggering device that requires custom software (unless its built specifically for android) But the device supports a USB keyboard just fine and I can react to the keystrokes that I am interested in from within my software. | |

If they are irrelevant, they can be removed altogether

| Dec 12, 2011 at 20:54 | comment | added | Michael Kohne | Why do you want a broadcasting keyboard? Typing the same thing on multiple devices at one time isn't usually a useful thing to do - what's your actual application? Perhaps with that info, we can come up with a more appropriate solution. | |

| Dec 12, 2011 at 20:13 | comment | added | FoamyGuy | For my purposes I won't be dealing with any special keys. I need to send only a small subset of the keys on the keybard. And they will all be normal letters. | |
| Dec 12, 2011 at 20:08 | comment | added | Clockwork-Muse | The hub works because the computer still recognizes the (individual) keyboards as seperate devices (which is why you can plug in both keyboards and mice, and have them both work) - I'd imagine that the USB protocol handles this (although I don't know how). For your request... how would you handle something like turning CapsLock/ScrollLock/NumLock on/off? Keep in mind that NumLock can be set pre-OS from the BIOS menu, and is reported (and displayed) from the keyboard. You'd likely need a special keyboard for this, not a hub. | |
