Hi,
My setup works fine with 2.6.28 but I need to upgrade to use Tony's
tree so I tried the tmlind/linux-omap-2.6.git tree with tip
0bbf5337f2f2957775051a3caf60b66d3306c815. This tree has broken USB
host on beagleboard RevC. dmesg shows:

Any suggestions what patch to try to solve this? I have tried
disabling autosuspend/resume, and then OTG, and then GADGET, and the
end result is the same.
