Ofcourse, this all depends > on how low-level you can go on that connector... It is possible. But you need some additional electronics, probably a MCU which handles the USB protocol. Do you just want a blinking led? Then a dedicated led controller chip with I2C interface should do the job (for example the TLC59208F, http://focus.ti.com/docs/prod/folders/print/tlc59208f.html). For a external, detachable solution, USB and a MCU may be the better option.
