Hey Guys,

I'm trying to setup a Beaglebone Black as the subject. I've followed 
the instructions and I get lots of this when I try to make it do it's 
thang:

[ 3142.831914] CAUTION: musb: Babble Interrupt Occurred
[ 3143.107609]  gadget: setup: failure req 9 v 1
[ 3143.289034] CAUTION: musb: Babble Interrupt Occurred
[ 3143.289088]  gadget: disconnected
[ 3143.564615]  gadget: setup: failure req 9 v 1

[ 3145.179357] CAUTION: musb: Babble Interrupt Occurred
[ 3145.179415]  gadget: disconnected

Any pointers? Web search comes up fruitless except for references to 
the kernel source code which I don't understand. ;)

Thanks,

John.
