Sysprep cleans Hardware Enum?

[RepublicOfTaiwan]

I am creating an XP SP2 image. I installed some USB drivers and saw USB
devices were enumerated in HKLM\SYSTEM\CurrentControlSet\Enum\USB. After I
run Sysprep and restarted the computer, the devices in
HKLM\SYSTEM\CurrentControlSet\Enum\USB were all gone. When users plug in a
USB device, Windows will ask for a driver.

What's strange is I used the image and did Sysprep again. The second time
the devices would NOT be removed from
HKLM\SYSTEM\CurrentControlSet\Enum\USB. Then again the 3rd time the devices
were removed. Then again the 4th time the devices were not removed.

How do I let Sysprep always keep hardware enumeration?

I found the following KB that is similar to my problem.

Every time USB drivers were removed I could see Sysprep.exe did that in
SETUPAPI.LOG. This happened every other time I run Sysprep. Is this another
race condition?
