When it asks you for the location of the driver, point to the flash drive.
It's not a CD/DVD/Flash Drive issue. At least not for the 6405. I could browse to the correct directory on the supplied installation CD, but the drivers weren't current. And when I tried to load the NEW drivers that I had downloaded from Adaptec, they weren't recognized.
The only way I finally made it work was to keep the old install CD in the drive till it asked me for the drivers, then replace it with the new driver CD that I had burned, and THEN put the old install CD back in the drive.
Yeah, it was weird...and I almost returned the controller.
