I have a powered 7 port USB hub on my computer. The only things plugged in are an external IDE drive and a cord that I can use to hook up my Blackberry on rare occasions.
My keyboard is not USB, it is PS2, but I have noticed that with the USB hub powered up, the lights are lit on my keyboard with all power to the computer turned off. I have a master power board and when I turn my computer off, I hit the kill switch on the board and all power to the computer is dead. The USB hub however, is plugged in elsewhere and remains powered.
When I start the computer, my keyboard is locked up and does not work. If I unplug the power to the USB port, the keyboard works fine.
The OS is not involved here but I am running an ASUS M2N68-VM mb. with and AMD Athlon 64 X2 6000+ CPU in an Antec full tower Dragon type case.
Does anyone have any idea what is causing this feedback from the external powered hub to the PS2 keyboard port? And more importantly, how to fix it? Any and all help greatly appreciated. One other thing, I have had this hub for a few months and all worked fine until the other day, and I have added no new hardware.
