FreeBSD asus 4.10-STABLE FreeBSD 4.10-STABLE #0: Wed Sep  1 15:19:17 PDT 2004     root at asus:/usr/src/sys/compile/ASUS  i386

>Description:
      Booting FreeBSD 4.10-stable with a Western Digital WDXB1600JBRNN 160GB disk drive attached to USB port on an ASUS A7N266-E motherboard causes a panic.  Booting the 5.2.1 CD with the drive attached and powered on causes a panic in the device probe phase most of the time.  I was able to do a sysinstall to the drive of 5.2.1 from the CD with the drive attached to USB0, never from USB1.
>How-To-Repeat:
      Attach the USB drive to USB0 or USB1, power it on and boot.
>Fix:
      If boot with the drive powered off, FreeBSD boots.  Then, power the drive on.  It acts normally.
