Once the S3U executable is started, a graphical user interface appears. The Vendor and Product Identification information is entered by selecting the Configuration option under the Options Menu on the top taskbar.
If the identification codes are not known, select the Scan USB item under the Debug Menu on the top taskbar. Provided there are not many devices on the bus, the codes corresponding to the flash memory under test should be easy to identify. The USB bus can be rescanned as many times as desired.
Once the Vendor and Product Identification codes are entered, select the Capacity and Inquiry items from the Debug Menu on the top taskbar.
