sztupy there is a large set of registers which can be triggered by the kernel in the FSA92xx chip... The FSA92xx is the chip which senses resistance like short for OTG or 301kohms for Download Mode. This set of registers controls all parameters. there is a "Switch I/O Voltage" which looks interesting.. "All other pins" is 5V.

I have set them off once before and lit an LED very brightly by accident.

If you'd like to contact me via PM or google talk, I can work with you and test things via UART in order to attempt to get the USB 5V working. I can set these registers manually.

I very much want to get my Arduino ADK working so I can do cool stuff with the Host controller. Lets work this thing out. Maybe you can help get this mod spread to the Captivate as well

So does it mean that it is possible to achieve true USB OTG [i.e., without the need of powered USB HUB] on SGS?

It would be good to have this!! From the specs for SGS' motherboard it does seem to support true OTG. And with the ability to read from an NTFS formatted drive, the possibilities are limitless!! We will hit truly unlimited storage on this phone!

It would, but you don't actualy need to connect 4-5 pins together, it's just for auto-detection. My code has support for "simple" inverted cables using "auto-host" mode (which will trigger host mode for every type of cable plugged-in)

Thanks to the info! I'll definitely look into it. I was also thinking of getting a simple LED to light up. I also looked at the host controller of the SGS2 which is definitely the same. Someone with an SGS2 might help me checking whether it supports USB 1.x devices (OHCI mode), or not. (I don't care whether they are actually working, just need to know whether they get enumerated or not)
