I started thinking when I tried this git.ti.com 3.8 kernel, I might have done 'devmem2 0x47401c60 b 0x81' to manually set the SESSION bit after plugged a device. It was months ago, I don't quite remember what I tested. My build server is down this afternoon. Once it comes back next week, I will try 3.8 again, to see how I can help on this USB1 host mode issue. its devctl register should stay on 0x19 even nothing is connected. > > Sebastian -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
