Author: mav Date: Mon Aug 15 14:19:26 2011 New Revision: 224886 URL: http://svn.freebsd.org/changeset/base/224886 Log: MFC r224511: - Fix usbhidctl and usbhidaction to handle HID devices with multiple report ids, such as multimedia keyboards. - Add collection type and report id to the `usbhidctl -r` output. They are important for proper device understanding and debugging. - Fix usbhidaction tool to properly handle items having report_count more then 1.
