Has anyone actually got this going? The WP77xx Product Specification describes a circuit for supporting OTG at Figure 5.6 (page 93). However no such circuit appears to be on MangOH Red or Yellow.

I was using Release 11 of firmware. I upgraded to Release 12 and now it works. Can plug in USB flash via USB-OTG cable, mount, see files.
