Thanks Dave. All of my lap tops keep the USB ports powered ... i know i could shut them down when the computer is off, but i keep GPS
dongles connected even when they are off.? I'll try the dmesg -WH and see what i find.
It is strange that the KPC-3 with the FTDI serial to USB dongle has no issues, but the -3+ USB does.
