I am porting Tizen 2.2.1 on ODROID-U3 board, and this work is almost done. I enabled 'USB debugging' in preferences app and plugged it to Host PC through USB cable.
However, on the host PC(Ubuntu 13.10), 'sdb devices' command does not show any devices at all. Host PC cannot even recognize ODROID-U3 with Tizen as USB storage. When I run Android(a version given by manufacturer) on the same device, ODROID-U3 is successfully connected to host PC through adb or USB storage connection. I think that I forgot to port something required for SDB or USB storage connection. Tizen on ODROID-U3 is using Kernel 3.10, which is based on the Tizen source code and built by myself. I recognized some code related to USB-OTG support in "arch/arm/mach-exynos/mach-smdk4x12.c"(ODROID-U3 uses Exynos 4412.) and "drivers/usb/gadget/s3c-hsotg.c". SDB-related code is also found in "drivers/usb/gadget/f_sdb.c". I guess that this kernel have enough code to support SDB and USB stoage connection. However, I don't know about the full processes of them, so I cannot ensure it. What components are required for SDB? If I know the components, I could resolve this problem. Please tell me about it.
