So my USB DVD drive needs more power than a normal USB port can deliver.
Normal Person: I'll bring it back to the store and get a diffrent one.

    Nice engineering

    Does it work?

    It's always nice to make things by yourself, but such y-formed usb cables are readily available in every electronic store.

    If the external drive needs more than 500mA it should already include such a cable (provided you bought a complete device and you didn't assemble drive and case yourself)

    @dontPanic Yes it does! Before I had a lot of dropouts but now its perfect :)

    @ddephor It draws 1.3amps at max and there was no exeternal power input nor such a splitter cable. I think some engineer at Samsung messed up a bit.

    @JFK422 1,3A? Aah, you used three cables? Ok, that's not what you get at the electronics store.
    But if it's supposed to be run on USB power something's really wrong.

    Wait, it's been a while since I took electronics but doesn't that double the voltage?

    @devios1 If you would connect it in series it would add up the Voltages. I connected it in parallel, which adds up the current.

    @JFK422 Ah thanks I had it backwards. :)
