Installing fine from a USB stick here. I grabbed CD1 of the X64 discs, and copied to USB using dd: dd if=/path/to/thedebian.iso of=/path/to/usbstick/device (replacing the if and of with your paths of course -- note: all data on the usb stick will be erased, and make sure you've picked the right device!)
