Honestly, it's much easier to play directly from a PS1 disc if your PS3 is backward compatible. But if you insist on using a USB, just make sure the files are correctly formatted and use the XMB to find them.
Make sure your PS3 is compatible with PS1 games. If it is, just transfer the PS1 game files to a USB drive, plug it into your PS3, and navigate to the Game menu to play your favorite classics.
