I have tried both FAT and FAT32. Below follows an edited screendump of some usb commands with a u-boot snapshot version from 13.01.2009.

I do reproduce exactly the same kind of problems here. As I originally said
in my October 9 mail (Message-Id: <1223564465.6130.20.camel at galileo>),
correcting the bootstrap PLLB settings made USB work, but USB storage
did work only with one of my three USB sticks.

I suspect the rest of the issues to be USB specific and not hardware
specific at this point, but I haven't looked closer into it.
