Above, you'll notice a couple of lines do not report an ABS_X value, so perhaps the driver is interpreting that to mean ABS_X has a value of zero, rather than no change?
Also, this tablet is a UC-LOGIC WP8060U as mentioned above, sold under the Monoprice brand, in particular this one: https://www.monoprice.com/products/product.asp?c_id=108&cp_id=10841&cs_id=1084101&p_id=5553&seq=1&format=2
