Summary: gadget zero control may hang at test 14 in bf548-ezkit
Gadget test in bf548-ezkit is not as stable as in bf527-ezkit.
For example, gadget_zero test may fail at test 14 occasionally, and it's hard to reproduce.
bf527-ezkit has better result and gadget test always pass.
Trunk and 09r1 branch has the same problem.

Updated Host OS's kernel from 2.6.25 to 2.6.31.
This bug disappeared.

Update kernel and can't see this bug now.
So close it.
