Handset Vendors Plug Micro-USB Charge Ports
ketan324 points to a Register story touting an agreement among several phone makers to settle on Micro USB for their phones' charging ports, writing "It's about time for these cellphone manufacturers to wise up and design a universal phone charger. Although many manufacturers have already 'standardized' to a mini-USB interface, there are many more out there who use proprietary adapters. I wonder how Apple will feel about this? Will they finally realize that their oh-so-special adapter is nothing more than a fudged USB interface?" No legislation required.
On the other hand, they specifically implemented an authentication chip that prevents video output on newer ipods if you use anything but officially blessed cables. There are certainly reasons for the dock connector; but that doesn't change the fact that Apple's approach toward accessory makers has pretty much been "flip over and shake until money stops coming out".
Because that when the device is not identified by the OS, the power output is capped to 100mA. When identified, it can go up to 500mA.
The evident solution would be to use a standard passive driver.
Stupidity is the root of all evil.
