Asus P4C800-E Deluxe MB (Pentium 4)\nWindows XP SP2\n\nFor the past few days, if I boot my PC with any USB device plugged in,\nit will freeze when loading Windows. Hang happens regardless of where\nI plug in the device (on-board ports on MB, ports on a USB PCI card,\nfront panel ports) and will even hang if booting in Safe Mode. I get\npast the Windows XP logo screen, then the screen goes black and right\nbefore I would expect the actual login window to appear, the screen\ngoes black and I hang. If I boot with no USB devices plugged in,\neverything's fine.\n\nIf I boot up with no USB devices plugged in, then plug in a USB device\nafter bootup, the USB device works fine and no hang.\n\nBoot logging shows lots of driver load successes and failures (in fact,\nlots of duplicate lines which I find puzzling) when USB device is\nplugged in.\n\n- Tried CHKDSK on all drives\n- Installed latest BIOS (1022)\n- Checked fan speeds, temperatures, and power via AsusProbe(all normal)\n\nI suspect this is really a Windows XP issue (driver maybe?). I did\ninstall some security updates before the reboot when I first noticed\nthe issue. I reviewed all of the updates and couldn't find any that\nseemed like they could be related though. I may try uninstalling all\nrecent updates if I can do so but would like to avoid that if its going\nto be a dead end.
