Emulation usb drive
Vuk, author of the first version lgmod wrote the following: Tried to use virtual dummy_hcd & g_file_storage to emulate virtual USB Host bus & Storage device as SamyGO guys do but seems it does not work in our case. If I load these modules before RELEASE TV set can't see hardware USB buses at all. I think it's hardcoded in RELEASE to init and use only USB host bus #1 & #2. If I load modules after RELEASE it settles as host bus #3 but any attempts to use virtual storage thru g_file_storage failed with device enumeration error... So real hardware stick still must for us..

To compile dummy_hcd.ko & g_file_storage.ko on Saturn 6 kernel, you need:
go to: Device Drivers->USB support->USB Gadget Support(M)->USB Peripheral Controller->DummyHCD(X) and: Device Drivers->USB support->USB Gadget Support(M)->File-backed Storage Gadget(M)
You can find compiled *.ko modules in Drivers/USB/Gadget
RELEASE mounts connected flash drive at startup, even if it is already mounted
It always does it and it is impossible to disable it by now...
