Driver Signing warning using pre-installed proprietary USB storage drivers
The message regarding "damage my system because it is not a Microsoft product" does not refer to the Centon hardware. It is referring to drivers already installed on your computer from your computer manufacturer. Some computer manufacturers installed their own non-Microsoft set of drivers for USB Mass Storage devices on mostly Windows XP systems. Generally it is safe to use those drivers. You should be able to find more information from your computer manufacturer regarding this issue on their support pages, or by contacting their support team.
In general, the Microsoft drivers for USB Mass Storage devices are stored in the C:\WINDOWS\SYSTEM32\DRIVERS folder. USB flash drives require the usbstor.sys among other files. The following procedure may assist in restoring Microsoft signed (i.e. official) drivers, versus any proprietary driver that may have been installed on your computer.
