Hello, I have a ASUS P5L-VM1394 motherboard. Specs are included in my profile. A computer that I built a couple of months ago. When ever I have my USB external DVD writer powered on when I boot up it is very slow to get past the Asus post and when I have my 4 port Belkin USB hub on, it will not boot into windows - just hangs on checking USB area in the post. If I unplug them and reboot the computer will go though startup quickly. I have the latest Bios update from ASUS for my MOB. 0903. Also downloaded a update from ASUS for my MOB about MS KB817900 USB fail to enter S3 patch file for Windows XP. Was a registry file. Entered it into the registry. Do I need to go into the bios and set something different in the USB configuration? I have the USB function - enabled/Legacy USB support-Auto/USB 2.0 controller - enabled/USB 2.0 controller mode - HiSpeed/Bios EHCI hand-off - enabled. The setting recommended in the MOB guide. or is it something else? Hate to always have to start by USB devices after booting and remember to turn them off before rebooting. Any help or information would be appreciated. Nola1031 UPDATE! 1/10/08 - Resolution! In case anyone else has this problem, this might help. This was a problem with both ASUS motherboards (P5L-VM1394.) from the get go. Had to change USB configuration settings in bios in order to get past post in the usb area when booting up with usb hubs plugged in. Changed the USB 2.0 controller mode. Set mode from HiSpeed to Full speed and un-enabled Bois EHCI hand off. Computer now boots fine with 2 different usb hubs plugged in along with USB DVD writer.
