WITHOUT A DOUBT one of the biggest flaws of the USB standard is the childishly low amounts of power that can be provided and it's been a major bugbear of the USB protocol. USB 3.0 upped it slightly, but 900mA is hardly what we'd call generous, but it seems like Intel has finally caught on and is considering some serious changes.

According to an IDF presentation by Abdul Ismail, who's a software architect at Intel, that we had a browse through, Intel is considering making some significant changes to USB as we know it. How much of this that will turn into actual final products isn't known, but hopefully Intel will decide to implement just about all of it. The key thing we'd like to highlight is what Intel calls PDC or Power Deliver and Control. Now, we didn't attend the actual presentation, so we're most likely missing a few bits and pieces. PDC is meant to allow USB devices to have the ability to read and/or report its power status and this would then allow the two devices to decide how to interact with each other when it comes to power delivery as well as which device is in control.
