Yes, USB stick is powered on, the green led on the stick is on. > > And the CPU version you used is 1.0, so your board version should less > than B2. > I'm not sure whether this affects the results. > I've tested another USB stick with this board, and was recognized properly. Also, the problematic stick works fine with Linux, so I still suspect there's a problem in u-boot EHCI driver. Can you test your board with smaller/older devices, the one that has problems is 512MB Sandisk Cruizer Mini. Thanks.
