Follow-ups

--- Vivi Li 2011-11-23 06:08:11

This test used to be done in bf527-ezkit 1.4 board, now we don't have such board

and test is done in 2.0 board.

Also bug 6777 still exists in bf527-ezkit and I'm not sure if they are related.

--- Bob Liu 2011-11-29 01:56:29

Can't reproduce, but my host machine is 2.6.31 instead of 2.6.25.

zero gadget: zero_autoresume --> -22

is just an info message, if using "modprobe g_zero" without

autoresume=5, there is no such print.

--- Vivi Li 2011-12-05 04:53:57

I try to test with bf527-ezkit board version 2.2 instead of 2.0, and also I

don't switch too fast, it works better.
