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.
