Subject: [U-Boot] [PATCH 2/8] USB add macros for debugging usb device setup.
Date: Fri, 4 Sep 2009 15:12:44 -0500 [thread overview]
Message-ID: <1252095170-5492-2-git-send-email-Tom.Rix@windriver.com> (raw)
In-Reply-To: <1252095170-5492-1-git-send-email-Tom.Rix@windriver.com>
When developing usb device features, it is useful to print out
common usb structures.
