Is there anything that connect to plug that would enable me to use it with a single port vs the double port it has to use now? I've got both an external hard drive and this external cd/dvd player and I can't use them both at the same time because they both need to use the double plug on the side of the computer.
That is not the same animal. The double USB on the PD01S are married together into one plug, not two seprate plugs like on many other external DVD drives. One side looks like a standard USB while the other half is just for power (no data) and has a block that prevents plugging in a true USB plug.
