[U-Boot] [PATCH] Fix to make U-Boot work with more USB sticks

[Simon Glass]

Hi Aaron,

OK good. Yes I notice ext2 is slow also, but the dcache is still off so I
assumed that was it.

I have had no hub problems, but have only tried two types. I do recall a LUN
patch floating around. I was going to try with an uSD card to see if it is
needed there.

Regards,
Simon
