Sorry for being insistent :
Is there any explanation why this issue only came up on Jocke's MPC8321 
(?) and my MPC8377 ?

As mentioned here 
(http://lists.denx.de/pipermail/u-boot/2010-November/081459.html) 
there's still a mysterious issue which might have the same root cause.
Again : USB is working fine under Linux - it's an U-Boot only issue.

Is anybody willing to have a closer look - I'm completely stuck here.


Regards,
André
