[U-Boot-Users] AT91SAM9261-EK USB storage not working...

Hello Stelian,

That is at least some good news. It confirms that I did not introduce
this problem myself :-)

I am very certain that it worked on 1.1.5_atmel_1.4 version, with
exactly the same USB memory stick as the one that does not work on
thecurrent releases...
So, I can rule the USB stick as well...

I agree

I hoped someone already had a solution, that why I asked you ;-)
and yes, it _must_ work here, and I believe I have to dig in this
myself. Maybe next week...

Kind regards,
