There is a report that reading of surface/button switch feature report causes SYN1B7D touchpad malfunction. As specs does not require it to be readable assume that report usages have default value on attach and last written value during operation. Do not apply default usage values on attachment and resume. While here fix manpage typos and add avg@ to copyright header. Reported by: Jakob Alvermark <jakob_AT_alvermark_DOT_net> Reviewed by: avg Differential revision: https://reviews.freebsd.org/D28196
