I've also tested it on the Panda, and gone through this and most

To make it easier for someone to test, I've extracted this
and the 6 dependent series from patchwork, and hosted

against v2.6.38-rc4 here:

git://dev.omapzoom.org/pub/scm/anand/linux-omap-usb.git

in the display-patches-for-v2.6.38-rc4 branch if someone
wants to take a look.
