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.
