When you disconnect a Universal Serial Bus (USB) storage device (such as a removable disk drive) attached to the root hub, an external USB hub that is also attached to the root hub may be disabled, and may cause all devices connected to the external hub to be removed. Also, this problem tends to occur on faster computers, such as those running AMD Athlon processors (CPUs).
