Re: BeagleBoard C4 with USB

For people from the future searching for clues:

In meta-ti the USB-enabling configuration options come from the 
connectivity.cfg fragment.  From inspection that's added to all the 
boards supported by meta-ti's linux-ti-staging_3.14 recipe, though I 
didn't look to see whether there's a problem with it on beagleboard.  It 
doesn't look like it'd be incorporated into linux-mainline, though, so 
perhaps that's why it wasn't present in the original problem report.

For beaglebone (and presumably beagleboard), you can also get the lsusb 
error -99 because the musb modules that support host USB are not 
installed by default.  Easiest way to get those (along with everything 
else you might need) is to install the kernel-modules roll-up package.  
That's in MACHINE_EXTRA_RRECOMMENDS for beaglebone in meta-yocto-bsp, 
but not in meta-ti.

The 3.14.17-based ti-staging branch has a lot of really neat stuff in 
it; it's going to take quite a while to explore and figure out how to 
use it.
