Greg, Is there a document/tutorial on the USB 3.0 driver code flow in general, especially regarding the OTG decisions process? I am interested in both: (1) my Samsung (android linux) defaults to a host at 2.0 when a 3.0 OTG gadget is plugged in, posting a pop-up to select 3.0; I'd like to have it default to 3.0 in that case. I'm also interested in your thoughts on what it would take to make the large file data transfer (isochronous?) rate approach the 3.0 spec maximum, even if it means compromising other transfers. I'm somewhat familiar with the 3.0 spec, but not the driver. Any pointers gratefully accepted.
