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 talking about the Enhanced Willem Universal Programmer. Perhaps, the two of you were talking about another, possibly hypothetical flash programmer.
Disclaimer: I'm not using the newest Willem programmer, but I think even the newest Willem programmer still uses USB only for power (They include the option of an AC adapter that can be used instead of the USB cable - an option my USB only powered, older unit lacks).
you are right.
- download image to burner buffer, NON USB need to 5s..., USB may only
need 1s. 2. issue command to burn from buffer to flash. .... burner need 30s, flash_rom need 10s.

I hope I could get one with USB2 cable and it could work with Linux.
USB2 would be faster than others.

I don't think it matters. Your bottleneck is not the bandwith to the programmer but the time it takes for the flash part to write a byte or block. Flash writes are slow.
