Your zxy100 driver is buggy, probably some structure isn't initialized correctly. When I had similar problems, I started to pepper my kernel with printk("#HS %s:%d\n", __func__, __LINE__) statements, to so where the execution path went. Occassionally I also printed the contents of values. It also helps to look at similar drivers... or to ditch zxy100. After all, there's drivers/input/touchscreen/usbtouchscreen.c, why should one invent a whole new USB touchscreen driver if one is already present? -- unsubscribe: android-porting+unsubscr...@googlegroups.com website: http://groups.google.com/group/android-porting
