Gary,
I tried with qemuarm machine in the yocto tree. And I find the usb devices
are working when compiled with gcc 4.6.0
Can you try it on the beagleboard?
Also, it's not that the USB device isn't found, rather no devices connected to
the USB bus are discovered.

Yes, that's the only change. Building the kernel from the same
source repository with 4.5.2 (using patches from you and Khem Raj)
works perfectly.
Hi Gary,
The yocto-linux kernel had to go through few changes to mute some
compiler warnings with gcc 4.6.0. Are you building your own kernel?
Yes. It's roughly based on the Angstrom 2.6.37 with BeagleBoard
support (I have additional OMAP boards which are not in the public
tree).
