Wobbly usb port also had 20 ohms of resistance across it.

(Who even checks that on their USB ports?)

@joeyh /me raises hand
I haven't checked a USB cable's resistance, but only 'cause it hasn't come up yet. I have checked voltage on USB during troubleshooting. Part of my EDC is a pocket multimeter so that I can test power and data cables. Worth the occasional WTF? looks. :D

@joeyh common on the data lines to signal different charge rates, but shouldn't be substantial for a power line from source to destination
