One is connected to the programming interface, so the one you currently use for downloading and programming. The other one is connected to the LPC1768 itself, which also has a USB peripheral. You can for example program it to emulate a mouse: http://developer.mbed.org/handbook/USBDevice

The LPC1768 can also be a USBHost, but I don't know if the Seeeduino is setup for that (requires a slightly different setup around the USB connector).

Accepted Answer

Hi, Erik, thank you for your comments. Can I find how it is connected to LPC1768 itselt? I failed to find it in the schematic provided by SeeedStudio.

I think the programming USB port is on the page with the LPC11u35, although it uses a different symbol than on the last page, which seems to be the one of the LPC1768.
