[Hans Petter Selasky]

Author: hselasky

New Revision: 277363
URL: https://svnweb.freebsd.org/changeset/base/277363

Log:
  MFC r277044:
  Increase the maximum number of dynamic USB quirks. USB memory stick
  devices which don't support the synchronize cache SCSI command are
  likely to also not support the prevent-allow medium removal SCSI
  command.
