This is about the charge plug on my tablet

[reble]

This is about an Android ZTE K90U tablet. The tablet uses a type C micro plug in for the charge/data cord. I have been trying to find a "Y" adapter that has a male type C micro plug to go into the tablet and has 2 lines coming out. 1 is a full size USB connector. The other side of the Y is a female type C connector. I want this so I can plug in a USB flash drive at the same time I can keep the tablet charged up. I have the tablet set to keep the screen on when the charge cord is connected. I have found a few Y adapters with a regular micro male, the female USB plug and a female micro plug. I tried this with a type C micro male to a regular micro female adapter. and the micro male charge cord from my phone. See the link of the drawing at https://www.dropbox.com/s/q4uqa91z7jkpg1x/type%20c%20adapter.jpg?dl=0 . The tablet didn't see the charge cord but saw the flash drive. I haven't found a Y adapter like what I want with a male type C plug.
