USB drive not visible

Hello, I've just got SMS media player, but I have little problem with playing movies from usb drive. Can somebody help me, please?

I'm using ULaunchElf to launch SMS 2.8 R2 from my ipod. It works fine but I can't see usb drive in avaiable media, only cd. Yes, I've got USBD.IRX file and I placed it in mc0:/BOOT/ but it still doesn't work. I also tried plugging in my mp3 player but it didn't help. What can I do wrong?

Press START for menu , Goto DEVICE SETTINGS , Goto START USB . I think that should do it . After this the usb should show up.

Yes, it works now. Thanks a lot :)

No Probs mate , Don't forget to save the settings so it will detect usb on startup
