I am running 9.0.53 and using a US Interface Navigator, with a built-in WinKeyer (version 23). The navigator connects via a USB port, and the WinKeyer shows up on my Win7 x 64 machine as Com7. When starting Logic9 up, about 40% of the time the WinKeyer initialization fails, causing the keyer to key the rig with random characters and usually displays and invalid response code error message in the WinKey window. After that burp, everything seems to work OK, but the inadvertent QRM is embarrasing.

My motherboard supplies power to the USB port even when the computer is turned off (unless you turn off the power supply), so Logic can't really control power to the WinKeyer chip. Is there an alternative way to initialize the keyer that doesn't depend on timing the power to it? Thanks and 73, Hank AA4HP
