    The file has several differences throughout compared to the armbian version. These are just a few of note. The values for some of the above properties are different in the default file vs the SimpleNAS dtb I used. I don't believe the OTG port was getting power before. There are other property differences throughout and everything appears to be working without issue.

    On OPiOne and OPiLite, there was similar issue that reg_usb0_vbus was not present.
    I've fix that a month ago with this commit :
    https://github.com/armbian/build/commit/fb0d3c6ea4b06df236d198af825d31a073dd2b81
    Maybe similar patch could fix it on BananaPro ...
