resource allocating for transparent bridge resizing works well and as expected.

looks like quirk for usb hand off cause problem.

can you try another branch in my tree?

git://git.kernel.org/pub/scm/linux/kernel/git/yinghai/linux-yinghai.git
usb_smi_disable_early

it will do usb hand off very early.

you can do:

mkdir linux-2.6 || exit -1
cd linux-2.6

git init-db
# Add Linus's tree as a remote
git remote add linus
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git

git remote add yinghai
git://git.kernel.org/pub/scm/linux/kernel/git/yinghai/linux-yinghai.git

git remote update

later will only do:

git remote update

git checkout -b rb_2012_01_19a linus/master
git merge yinghai/usb_smi_disable_early


Thanks

Yinghai
