No my PS3 is a pal slim, I did notice a ntsc option in the config file maybe you could try changing that option, also I had to have my usb device in port 2 on my PS3.
i also had to use port 2 but to get it to use the cfg on usb i had to delete the cfg on the ps3 its self using ftp
also got it to work on geo's fw by using PKG_Signer_GUI
