Author: wulf Date: Tue Sep 4 19:22:31 2018 New Revision: 338458 URL: https://svnweb.freebsd.org/changeset/base/338458 Log: wmt(4): Fix regression introduced in r337289 r337289 has a side effect of reducing usb frame 0 buffer size down to touch report size. That broke some devices e.g. "Raydium Touch System" which are capable of generating non-touch frames of bigger length. Fix it with enlarging frame 0 buffer up to internal wmt(4) buffer size.
