I am using a KVM switch (TRENDnet TK-207) to share my apple keyboard and mouse between my Mac Pro (early 2009) and my mac mini (intel) . Everything works pretty much normal as far as mouse functions and keyboard functions, I can switch between the two normally. The problem comes when both computers are powered off and I go to power on the Mac Pro, the KVM just blinks until I turn on the mac mini, then it will let me use the mouse and keyboard on the mac pro. I can shut down the mac mini and the KVM will continue to work normally until I power off the mac pro. I can put the mac pro to sleep and it will awake and the KVM will work normally. What should I be doing to find the problem?
