I looked at quite a few USB-To-USB cables that emulate network and none of them would work on Win7 x64. Some of them would make it possible to send files back and forth via special software but none would properly emulate LAN. So, I dropped the idea of the USB-To-USB idea. I looked at the option of having 2 USB to Network cards and a crossover cable but none of the USB to Network cards support Win7 x64 so far, even the expensive ones. So, I have ran out of options of putting 2 comouters on the same network.
So, I have a notebook on one internet line and desktop on another internet line and the idea for that is that it is more secure like that for the office environment. My office desktop is on the corporate network and my personal notebook is on another line, so there are no security issues there. Putting 2 machines on the same network would create a bridge that could be a security issue. So, having a KM Switch sounded like a good idea to me since it would be only a keyboard and a mouse that would be connected to both computers.
I asked a seller on eBay if
the device will work on Windows 7 x64 and he replied "Yes", so I decided to get it. It arrived yesterday and I have tested it on Win7x64 + Win7x86 and it works well. And today in the office I tries Win7x64 + WinXPProx86 and it works as well. There is a 3 sec delay though when I switch between the computers but this is the thing I am willing to live with for now.
I kinda like the idea of Synergy when you can move the mouse to the edge and it goes to another computer screen but then the thing is that the computers should be on the same network and in my case this is the security issue. If I would need to implement this at home when both computers are on the same network, I would definitely go for the
Synergy software solution instead of hardware.
