Do I need USB jtag ?

[Bruiser]

I did lots of SB5100, SB5101s with a parallel jtag. No problems. None at all.

When I used my 2x CD burner in 2001 I also did not have any problems.

And he's doing a SB5101. I had to get something newer to do the DOCSIS 3, but for that thing, old stuff is good enough as long as you are not going in production.
