Dear friends, 

 
I have designed a LPC1788 board and I am trying to develop a
program to use its USB host controller. I am using RL-USB and
RL-FlashFS file system. The layout is similar that of the embedded
artist&amp;#39;s board, located in:

So it seems that overcurrent pin is also important.&lt;br /&gt;
i had not used it, because it was not needed in lpc1768&lt;/p&gt;

Actually I found the problem. It turned out that the footprint of
my USB female connector was wrong, so I was connecting VBus to ground
(Short circuit).&lt;br /&gt;
You can check yours too. Check if the Overcurrent pin of your USB
power switch IC goes low. If it does, bang there is something wrong
with your hardware.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: LPC1788 USB host controller using RL-USB</title><link>https://community.arm.com/thread/64007?ContentTypeID=1</link><pubDate>Sun, 16 Aug 2015 13:05:54 GMT</pubDate><guid isPermaLink="false">dd9e70c8-6d3c-4c71-b136-2456382a7b5c:23f89d2c-c9cf-4d7d-9b93-89a55bc623e2</guid><dc:creator>john kachal</dc:creator><description>&lt;p&gt;&lt;p&gt;
This is the same Problem as mine but how hard I&amp;#39;ve tried ,I have
found no solution, it is in case that rl-usb have been customized for
lpc1768 which work well.&lt;/p&gt;
&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
