Firewire port on Antec Sonata Case

[JP5]

Has anyone had problems connecting the front Firewire ports on their Antec Sonata case? I haven't been able to get them to work using either set of headers on my IS7 motherboard. 1394 is enabled in the BIOS. It works fine from the front. I read somewhere that Antec mislabeled the + and - leads, but am afraid to connect my camcorder to a plug with reversed polarity (though it may be reversed now ).

I got an email from Antec's tech support. They said to try the different voltage headers and grounds. I did to no avail.

I still haven't been able to get the firewire port on the fron of the Sonata case to work. I've swapped the positive and negative leads. I've heard of others having this problem. Anyone else on the board had this problem?
