    Keyboard and Mouse dont work after cold boot

    frankDP55WB

      DP55WB keyboard and mouse dont work after cold boot. Using PS2 to USB adapter. Running WinXP. After unpluging USB, for 2 seconds and re plugging it, both work fine. Before unplugging USB the mouse pointer stays in the center of the screen. The NumLock led works but the CAPLock does not. When the USB plug is reset, all 3 leds flash and every thing is normal. This only occurs from a COLD boot. The keyboard is completely dead until the OS loads. Cannot enter BIOS setup with F2 unless I let Windows load, then reset the USB plug, then RESTART(warm boot). Latest BIOS (0165.2009.1110.1916) is installed and all the latest XP undates. HELP PLEASE

          Anyone who is using the DX58SO with USB problems at boot stage:

          I had the problem too.

           

          The problem was [solved] after installing BIOS 3044 dated 2008.

          And if this older BIOS relates to another problem, try the next higher version but the latest BIOS version can have the weird USB problems.

            My problem is with a DP55WB motherboard. There are only 2 updates for the Bios. This problem was supposed to be fixed in the second to last update (0142.2009.0909.2101). I installed the latest update(0165.2009.1110.1916). That fixed the lack of the single beep during post, but not the USB keyboard and mouse problem. Isn't the latest update supposed to be all inclusive? Since then I bought a new Microsoft USB keyboard and mouse. Still have the same problem. Now I have to reset BOTH cables to get either to work. This is definitely a bios problem. Most machines flash all 3 keyboard LEDs during POST. This one does not.
