Well, actually, if you have *only* USB port damaged, but all chips/peripherals OK, you could charge and calibrate using testpads under battery. Heck, you could even create a permanent workaround USB (both data and charging) this way.

But, a) it requires lottsa effort b) it's off-topic here. See "repairing usb port before and after it's too late" thread for further info.
