I'm really sorry about that Stephan. I knew coding style was not fitted but wanted some feedback and another pair of eyes tracking bugs. I'm going to work at coding style issue and hope to upload an updated patch soon. > I would hope that by making the TabletDevice work exactly as the MouseDevice with regards I started working on TabletDevice using a copy of MouseDevice, so despite specific tablet handling, It is almost the same, however some devices don't work the first time they plug and others fails when plugging for a second time. Input server add-on was quite deprecated and had some hardcoded values, so I suspect it is the source of some bugs. About the Track question, tablet devices I own publish a variety of reports; barrels, tips, pressure... I'm not sure what is the most standard way to emulate a mouse. There are some work to do in this part :\ I'm not an usb expert neither a tablet expert! But don't wanted to wait until some one get my gadgets working :-D Best regards!
