USB OTG Port as USB Host on Sabre-SD card...

I have not been able to get the USB OTG port on my Sabre-SD card to work as a USB host. It clearly works when I get the MfGTools v2 working but I believe it is a client in this mode.

When I plug in my Belkin hub with a mouse and keyboard attached they are not recognized. Any help in getitng these up and running would be greatly apprecaited.

Make sure the USBOTG ID pin (#4) is connected to GND in order to make an OTG port as host (officially "A-device"). The micro-AB to USB-A conversion connector I got as part of Emerge USB conversion kit has apparently open ID pin, making USB OTG port as device (officially "B-device").

What you need is adapter: USB Type A female to USB micro A male.


This is the one I used succesfully:
