It's more likely the solder is cracking off the PCB. Jiggling the port around forces it back into good contact and it'll sporadically work.

The real problem is we don't bolt the ports to the chassis in most cases, we just put them on the PCB with little bracing them in the direction of applied force.

As it turns out, this is addressed in the class specification. I wonder if it’s the spec that’s deficient or whether the devices in question are non compliant.

My first "hack" as a teenager was soldering a USB cable into the place the USB mini port was on a palm I was using as an ereader. The port would just become detached from the board if you looked at it funny; so this worked pretty well. I could just plug the whole device in to charge from then on.

Then I realized that the three volts that were supplied from a pair of AA batteries was really more of a suggestion. That summer, lots of gadgets I had became "USB powered"
