The top most string is called the PNP ID, right click and copy it to the clipboard. (ie PCI\VEN_104C&DEV_8033&SUBSYS_0300107B&REV_00)
3. Surf to http://www.pcidatabase.com/ in the device search box put the 4 digit hex code that appears after DEV_ in our example 8033, hit search and it will return a list of possibilities. Look in the Vendor Id column for the 4 digit hex code that appears after VEN_ in our example 104C appears at the very top as the vendor Texas Instruments and the description is an Integraded FlashMedia Controller
