What about OTG, Is it not supported? The constant (OTG_STATE_B_HOST)
will always evaluate to true.

Note: For the M2M, the vendor disabled the USB DEV (by setting the
reset signal in the boot loader).
They did this probably to save power (this unit has a battery). And
unfortunately: if the USB DEV
reset bit is not cleared, then the connected USB device on the USB
HOST (of the ramips) is not
detected.

Christian
