Sorry for that :)

Right. However the two board fail with slight different errors iirc.

Sure. However, I've double checked the Linux initialisation code for the
usb host on the AT91 boards and the U-Boot counterparts and there are
only a few differences (some VBus GPIOs to set on the AT91SAM9263, an
additionnal clock for AT91SAM9261), and I cannot find anything which
could go wrong here.

Sure.

I do have a SAM9263 in front of me waiting for your experimental
patches :-)
And I can do some extra tests on other Atmel boards, but this will have
to wait a week or so because I won't have access to them before then.

I tested with 2 different USB sticks, a very old 256 MB one and a more
recent 1 GB. They behave exactly the same.

See below.

Hmm, I can do that, but not before September 29.
