Author: thompsa Date: Tue Jan 13 19:03:47 2009 New Revision: 187176 URL: http://svn.freebsd.org/changeset/base/187176 Log: MFp4: //depot/projects/usb@155917 Remove dependancy towards the USB config thread in the USB serial core. Use USB process msignalling instead. Saves a little memory and hopefully makes the code more understandable.
