Did you first delete the book, unplug the reader from the PC, then connect it to the USB and resend the book?
If that doesn't work, you could try the Kobo Utilities plugin. It has an option to Upload covers for selected books, but it really shouldn't be necessary, it should display covers without that plugin.
