/+\Help with USBhosts and Daxziso and IR Shell Please!/+\

Hey all, My psp is FW version 3.40 OE-A, and I am trying to use usbhosts to load my backup of world tour soccer without saving it on the memory stick. However, it seems that when I setup the server for the USBhost and I connected it to Daxziso, when I chose my ISO the screen blacked out. After that I tried using IR Shell to load my backup ISO using a usbhost, but when i tried to load it I got an error, something like 800200D or something like that. Can anyone help me?

just buy a damn memory stick, is the least thing you could do
