Hi Fabio,

usbotg1 on Colibri iMX7 can function in both host/otg modes. In case
if dr_mode = "otg" is specified it obviously won't be enumerated
during usb start invocation.
For ums command actually it doesn't matter what mode is specified in
the device tree, as you explicitly specify usb controller to be used
during invocation (usage: ums <USB_controller> [<devtype>]
<dev[:part]>)
