This patch fixes USB 2.0 communication issues on some DU440 boards.
Is this a potential problem for other 440EPx boards as well? Or is it really only DU440 specific?
Best regards, Stefan

Hi Stefan,
this might touch other boards as well. A patch for our PMC440 will come up later today.
I have a support case with AMCC about this and ask them If I shall provide a patch for sequoia as well. I expect that someone will contact you about this issue.

You might want to switch to the 4xx-GPIO initialization via the CFG_4xx_GPIO_TABLE define at some time. This makes it much easier to configure the GPIO's correctly.
But if you don't want to do this right now, I can apply this current patch for now as a bug fix.

Hi Stefan,
I am aware of the CFG_4xx_GPIO_TABLE feature. I think there is also a TODO comment for this in my code. But right now I want to keep it as it is because of a lack of time.

OK, makes sense to me. I'll push your patches to the master branch for upstream merge later.
