How do I get save data off PC onto Wii U, when PC can't read Wii U's usb stick formatting?

No. They did this to stop the rampant SD card-based "hacking" from the Wii. You are out of luck and just paid a bunch of money for absolutely nothing. Sucks, but it is what it is. Not even through homebrew is it possible...yet.
