 Hi.
 
 I've found the problem and it's an easy fix the match routine for ums must be 
 broadened to cater for stylus':
 
 If you use usbhidctl -rvv you will see that the usage will be 0x13:0x20 for 
 stylus I now know that my touch screen was 0x13:0x2 for pen.
 
 Using usbhidctl is faster and easier than using printf.
 
 
 So the test for matching must be broadened by adding:
 
        !hid_is_collection(desc, size, uha->reportid,
                                HID_USAGE2(HUP_DIGITIZERS, 0x0020)))
 
 Please check that your usage id is in fact 0x20.
 
 Regards,
 
 Nat.
