ft232 avr as usb host

I would look into the new FTDI Host chip.

You would NOT want to do USB Host , in software on an AVR

Else look into a SD/MMC card , those are easy to do with an AVR.

Sorry I don't understand what you can?
In this interfacing, USB disk is 'client' (or 'slaver')
If you wan't to read or write into USB disk, You'll have to simulate USB HOST.
It's really complex.
:cry:I was afraid of simulation USB HOST, one of which create 1ms Header Frame (or same thing) and my MCU wasn't enough fast to run

Finally, I decided to buy a hardware chip support USB host :D
