Sorry, you are both wrong. The USB cable is used _only_ for power. All data goes through the parallel port. It is a slow (5 minutes to burn and 2 minutes to verify), cheap burner, but I have found it to be extremely reliable.
I was refering to any usb programmer. USB 1 can do 12Mbps. or roughly a 1MB/s but you can't program a flash at that rate. So you ether download the contents into the programmer or the programmer polls for when the device is ready to accept the next byte. In a polling setup a USB 2.0 device my be just as slow a parallel port device because its not the transport thats the problem. Its the implementation.
USB 2 devices however by virtue of being newer may indeed be faster but its not ncecssarly because they are USB 2.
