                Hi Guys, I have got 2 identical machines built. I have got DP45SG board, 2 GB 1333Mhz Transcend RAM, 9400 GT 512 Graphics card, an USB Mouse and PS2 keyboard(connected via PS2 to USB convertor to USB port) using windows XP - SP2. In one of the machines I am getting the USB issue as described in his thread. When the machine is booting, BIOS can recognise the mouse and keyboard. When the windows starts, I am able to login to windows but all of a sudden my keyborad and mouse stops working. Even after changing the USB ports it doesn't come up. Previously when such thing used to happen after changing the USB ports (means repluggin to other USB port) it could recognise the device. Keyboard's Caps lock keeps in ON condition, while in mouse there is NO light.


                I Checked BIOS, the "legacy USB" and "USB" are ENABLED. In this condition when the windows is booted and keyboard and mouse is not working, I tried to connect the USB Pen Drive to one of the port. The light of the USB drive is ILLUMINATED so the USB drive is up. If I remove this drive and try to connect mouse to same port , still the mouse light is OFF and it is NOT Recognised. This is the observation that if I install XP and try to install Audio Drivers that comes with Intel Board CD, this problem also comes during and after installation of audio drivers.


                I wonder if it's really that USB losing power, or there is something else to it? Any Intel Guy pls help to resolve the issue ASAP
