Micro usb touch screen clicker

hi! i bought these chinese auto clicker for your phone, with a micro usb connector. i didn't get the hub because it has limited programmability, and tried connecting its 4 wires to arduino.
although the blue light indicates it gets power, it doesn't click the screen. am i doing something wrong? thanks beforehand
i tried a couple combinations but i'm not sure how to utilize the d+ and d-
four wires of micro usb
vcc -> 5v
D+ -> 2
D- -> 3
gnd -> ground


Please post a link to the datasheet please.
