I've got one of those charging stations on my desk with a powered USB hub inside it. The problem is that it doesn't charge anything when the PC is off. Power still goes to the ports (tested with a multimeter), but my iPhone (or anything else for that matter) won't charge because the data wires don't get shorted with a resistor or anything like wall-chargers will do.
Is there a dock or USB hub that can automatically switch between syncing with a computer and charging through A/C power?
