Wacom Intuos Pro continues flashing a single white light, and no longer responds on any computer or with any USB cable, is it the battery or the wiring inside?

Its a Wacom Intuos Pro Small i've had since 2014, so its not incredibly old and not very worn, it worked for months on my desktop mac. Then recently i acquired the newest macbook, installed the driver and it worked there too for a while, until recently.

The computer would flash messages like "the USB device is drawing too much power, remove it" and then suddenly the tablet wouldn't respond at all, with that USB Chord. I switched to a new USB chord and it worked again, for about 3 days until the same thing happened with it.

No USB chord has worked since, and the tablet wont even respond on my old computer anymore. It simply flashes a single little white light on the surface by the touch wheel, and the battery light shines orange when plugged into the computer, HOWEVER when plugged into the wall it shines green indicating the battery is charged (I assume).
I removed the tablet utility and the drivers half a dozen times, kept installing different version or the newer versions of the drivers on the macbook until i eventually gave up.

I don't understand, it cant be the computer because the other computer doesn't read the tablet either, it cant be the tablets ability to maintain a charge because it flashes green when plugged into the wall....what could possibly be the problem?
