So I've been seeing USB issues on my beagle xm board with the latest linaro-2.6.38 tree, where when the system boots, lsusb will only show the hubs, but no devices.
Andy reported seeing similar on his overo board, so I bisected the issue down to:

Any tips here?
Hmmm... Do you have the same problem with 2.6.39-rc1? If no then the linaro tree might be missing something that is present in mainline.
Yep. I see the same as what Robert reported. 2.6.39-rc1 is affected as well.
