Windows 2000 does not find Drivers for USB storage devices

[Cixert]

In a new installation I have all the drivers well installed in the Device Manager.
The USB 2.0 is SiS chipset.
Now I insert a storage device into the USB port.
Then Windows 2000 says a new device has been found.
When I press the next button, Windows 2000 does not automatically find a driver to install.
Where can I find the USB Storage Massive Class driver?
In another previous installation I had no problems on this computer, but then I had introduced the USB device before installing the SiS USB 2.0 driver.

Solved!
I have been thinking that generic volume could be at "volume.inf" or "usb.inf" in WINNT/inf but on this route I encounter with surprise that these files do not exist.
Then I copy the WINNT/inf folder from another Windows 2000 installation and paste it into another hard drive folder on the computer with problems.
After inserting a storage device I say to Windows that volume.inf is the driver.
But Windows says it is not a valid driver, then Windows thinks that usbstor.inf is a valid driver.
Finally after installing usbstor.inf & it finds usbstor.sys on WINNT/system32/driver then the USB storage device starts working.
I ask, how is it possible to disappear *.inf files on WINNT/inf ?
I find missing 136 files type *.inf on WINNT/inf.
I am sure that they were there before, because instead of installing I paste the same system images into all computers.
