Omnia stopped connecting through USB, WTF?

I saw the news about CF03 and went to update, then I plugged the phone into my laptop...nothing. The phone nor the laptop signaled that anything had been connected.
I then tried to do the same thing on my desktop...nothing again. ActiveSync or USB mode, neither one works. I hard reset hoping that would fix the problem...nope. Then I tried the same on both after removing the microSD card, and then after installing the Samsung USB drivers. The AC charger works perfectly. So what do you think? Bad cable? It was working a couple of days ago when I used it. Hope to hear from you guys soon. Thanks!
