I guess because most people don't use UBI on NOR yet.

I am using the unreleased ELDK 5.8 (gcc 4.9.2) and debian gcc 5.2.
Which gcc version is in the mentor toolchain?

Can you try it again with u-boot/master ? I'd be interested in your results.
Can you share the entire output of the U-Boot and run 'dcache' command before
doing 'usb reset' ? I am seeing this issue with Sandisk Cruzer USB 2.0 sticks 
now too.
