Hi
I've recently acquired a BeagleBone Green with AM335x processor. I 'm
connecting a USB device (actually a 3D camera from ORBBEC) to the
Beagle USB host port. It recognizes well as I can see at the dmesg
output:
[12411.643517] usb 1-1: new high-speed USB device number 2 using musb-hdrc
We added some error handling to this function but forgot to set the
error code on this path.

You could send me your dts changes as patches, I will append it at my v2 patch
series.
My board is currently off-tree so I can't send any patch for the pinmux
settings in
devicetree. But I will send a patch
Smatch complains that "reg" can be uninitialized if the
abx500_get_register_interruptible() call fails. It's an interruptable
function, so we should check if the user presses CTRL-C.
