I did try mangling a USB cable in various ways arriving eventually at just the data lines and it killed the noise but also the connection! No USB device found. It might work in other contexts as I found various posts online where people had had success.
Have you tried connecting a 5V supply? I suspect something needs to detect 5V in order to work, even if the current pull is minimal.
Don't know about you but I must have at least half a dozen 5V supplies about the place and several at other voltages.
