Are you using original cable ?
Long cable tend to be slow charing
I just received my Note 10.1, a used one with 3m length cable, and same as you, not recognized by the pc, I ordered shorter one on ebay
Also not sure Galaxy charging works for this tablet, but it's less than 0.5A when using this cable, sooo....
