>Environment:
System: FreeBSD 8.0-BETA2 amd64
>Description:
It is sometimes useful to see how various mouse functions are recognized
by the ums(4) driver. One can recompile the kernel with USB_DEBUG, but
that's not always viable. Another way to proceed is to create sysctl
node that will show parser's data.
>How-To-Repeat:
Try to understand how bits in the output report descriptors are mapped
to the buttons and mouse movements by the ums(4) driver with the stock
FreeBSD kernel.
>Fix:
The following patch adds sysctl named 'dev.ums.<unit>.parseinfo' that
dumps parser internal state in the human-readable form.
