I received a DigiPro/UC-Logic WP5540 tablet today. While the hardware seems fine (as determined thanks to the default drivers Windows installed), using the manufacturer's drivers (v5.02, 2010-06) resulted in an inverted Y axis, and erratic movement (including some inversion, and some pronounced Y motion, but not always) on the X axis.
I'm running Windows 7 Ultimate x64.
Anyone else with this model of tablet have this problem before and figured out how to fix it? Going back to the default drivers doesn't count as I require the pen pressure ability (which the default driver doesn't support).
