Message-ID: <20080916125541.347606297@bohmer.net>> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: u-boot@lists.denx.de This series is a set of patches that are required to make USB sticks behave robust while using U-Boot on a OHCI host. Several users complain about ERROR: CTL:TIMEOUT errors while using USB sticks, and while testing many different USB sticks it showed that some were working and many don't. It even showed a compiler dependency while debugging this, where GCC 3.x compilers seemed to work (but not always) and GCC 4.x compilers usually don't. While debugging this (with a USB analyser of course) it turned out that U-boot also made several protocol violations that needed to be solved, these resulted in hanging USB devices and so on. In a mail thread with Stelian Pop on 28 July it was reported of a known error on Atmel cores that it did not work. I tested these series on Atmel AT91SAM9261 Core, with the common OHCI driver, GCC 4.2.3 (Code Sourcery G++ Lite 2008q1-126) REMEMBER: U-boot still supports 1 single USB stick at a time... --
