EU Commissioner Wants Standard For Mobile Phone Connectors
Jantastic writes "European Commissioner Günter Verheugen wants manufacturers of mobile phones to come up with a standard connector for chargers and microphones. If companies fail to do so, proposed legislation should speed up this process. In theory, this could improve competition, while enabling longer life cycles for these devices."
As spiegel.de, where I first read about Guenter Verheugens plans, says: "It's a nice idea, but 7 years too late, and your doing it for publicity only!" This commissions' term is nearly over (or at least close enough to being over for this plan to not have a rat's asses chance of being implemented while Guenter is still in office). Thus I can only agree with spiegel's assessment: Verheugen wants to go out with something attentiongrabbing (hereby accomplished) and those plans will be put back into a drawer once he leaves office.
Here's a pretty reasonable "de-facto" standard that says you are talking to a "dumb charger": if there is no data on the data wires and nothing connected to them at the other end, you're talking to a dumb "power only" supply.
Manufacturers could easily adopt this outside the USB spec, since there is nothing preventing them from doing so. They must follow the spec when attached to a real USB source, but if there are no termination resistors on the data lines at the other end, then they aren't talking to a USB source and can do what they want.
In fact, there is already a (pseudo?) standard for how to connect earphones/handsfree hardware using the same mini-USB connection, apparently based on the ability to detect the difference between handsfree hardware and a true USB source.
Most of the devices I now have have mini-USB for charging and communication. The Sansa MP3 player I have has some oddball connector, so it's the odd man out.
BUT, the Sony PRS-505 I have, even though it has a mini-USB connection for data, is, IMNSHO, broken because it will only charge via that connection IF is it connected directly to a primary USB host adapter and can enumerate itself on the bus. No hubs. No "dumb power supplies". Even if the hub is externally powered -- no charge! It will actually DISCHARGE the device completely in such a situation, because it will stay powered on attempting to communicate with the USB host while it is not charging from the USB connection, even if there is no USB host to talk to.
So, count me in the camp that considers mini-USB to be the defacto standard for connecting anything to anything, and that manufacturers that require proprietary cables for simple things should buy a clue.
