Help. I just bought a Tk-205K KVM switch and am having some trouble. I am using it to connect my computer to port 1 and my XBox 360 to port 2 via VGA cables. I am able to use both computer and Xbox as long as the Xbox is on. If it's off I can not use either. I do not wish to leave my Xbox on all of the time. Is port two what powers the switch? Should it work even if nothing is plugged into port 2. Also when I did have the xbox on and was using the device, my monitor turned a green color. Everything was green. As soon as I unplugged the device it was fine so I know it was not the settings on the monitor. Has this happened before to anyone else?
My problem is fairly similar to the first. When both xbox and computer are turned on the KVM switch works fine, it lets me switch back and fourth between the x-box and computer with no problems at all. IF i turn off my computer, the xbox will continue to run through the KVM switch without need of the pc. BUT when i turn off the x-box with the pc on, the kvm switch will not display anything. at all.. in order to use my PC with my x-box turned off, I have to hook the monitor directly to the pc. If there's a solution to this nonsence I'd like to know it.

I can confirm the same problem happened with me just now. I have TrendNet USB/KVM TK-207 and was flawlessly working with Logitech K260 Wireless Mouse and Keyboard Combo, but today on both computers all I can see is the error:
. USB Device not recognized - The last USB device you connected to this computer malfunctioned and Windows does not recognize it.
I unplugged the usb wireless adapter and connected it directly to the PC - it worked like a charm again. I have tried to connect the wireless adapter to the mouse port hoping that the keyboard USB port is causing problems, but all I got was the same error. I have tried to conect a normal USB keyboard, but again the same error I get for both - the mouse and keyboard, so it is more than obvious now that the USB ports of my KVN Switch are malfunctioning. I will try to leave it for a while if it got hot somehow as it was connected for more than 6 months working perfectly fine, but if not, I am heading to the store for support/replacement.
This is a common problem with KVM switches. To isolate the problem, here's what you need to do:
1. First, connect the keyboard and mouse directly to the problem
computer to ensure that the keyboard and mouse works correctly while
being directly connected.
2. Swap the connection of two computers. If you're having a problem on
the computer that is connected to port 1 of the KVM, connect that
computer to port 2 of the switch or just swap the connection. If the
problem recur on port 1, then there's a problem with the keyboard and
mouse cable on port 1.
3. But if you're not able to duplicate the problem on port 1 or 2,
disconnect the KVM switch from the computers, leave it disconnected for
4. After 5 minutes, reconnect the KVM to the computers and reboot the computers.
5. If same problem occur, then contact the manufacturer of the KVM and have them RMA the device.
As a wild guess, it sounds like a static discharge MIGHT be affecting the switcher causing it to crash.
Try increasing your humidity to 40% and grounding yourself before touching the keyboard... This is the season for these static electricity problems... get nipped all the time and you MAY not even feel it to be enough to zap the switch.
a repair is wise if this is a constant issue. Some people tackle this
problem by opening up their Xbox 360 and finding the problem
themselves. Those who do report a small magnet that holds the disc in
place, loose or not connected. They simply glue this back on; however,
opening the Xbox 360 renders the warranty invalid, therefore future
repairs may be denied and a fee may be placed.
