Description Jan Carlson 2000-12-23 00:44:09 EST
On every reboot, Flo Beta1 kudzu finds two unknown devices and then removes
them.
Disabling the USB function in the motherboard stopped the symptoms.

    MOBO = Asus A7V Socket A
    CPU =    AMD Duron 700

This section in  /etc/sysconfig/hwconf kept changing:
-
class: UNSPEC
bus: USB
detached: 0
device: none
driver: none
desc: "unknown"
-
This section did not change:
-
class: USB
bus: PCI
detached: 0
driver: usb-uhci
desc: "VIA Technologies|VT82C586B USB"
vendorId: 1106
deviceId: 3038
subVendorId: 0925
