One of the things I’ve been wanting to do for a while is put Isochronous transfer support back in to the 1394 Hybrid sample. Now that Windows 7 has shipped and we’re picking up projects we want to do during this period of product transitions, I felt the

Most of you at the DDC will notice that I'm not at the DDC. I'm guessing that makes me one of the "juniors" that Bob was referring to. ;) 4.) How do you build debugging techniques into your driver? Ie, DbgBreakPoint, ASSERT, etc - which is best in various
