The regular kernel HID driver defines the EV_ABS events with codes (ABS_xxx) up to 63 (0x3f), but hal_input only handles what is defined in lib/python/linux_event.py, where the highest event is ABS_MISC (0x28 or decimal 40), and throws an error when your USB device sends ABS_MT_TOUCH_MAJOR (code 0x30 or decimal 48) and higher. The Linux kernel driver uses codes defined in /usr/include/linux/input.h, so linux_event.py should be modified to match it; I enclose a patch that Sebastian can apply directly. I don't have the check-in privileges in the EMC2 git repo, so perhaps the original author of linux_event.py (Jeff Epler) or someone else could apply it there.
