ok.. iv got my hardware here..
5V supply is fine, think i may have confused myself when designing the usb bits though...
VBUSON and VUSB..
i tied VUSB to the enable of my 5V psu.. and VUSB to the 5V power line..
iv been looking at Section 27. USB On-The-Go (OTG)
and DM320004 User Guide Page 24.
and im none the wiser, but i think i should have put VBUSON to a mosfet switch thing like the DM320004, and VUSB to 5V as on the dev kit, but i dont know? nor do i know how to correct this..
cant quite put thumb on what exactly is wrong.. help
<edit>
and does someone understand what this does?
