I am not able to charge my iphone via my PC or wall electrical outlet anymore using the USB cable, however, I can charge it using my car charger.

Everything was working fine then this happened: i was disconnecting bunch of cables out of my motherboard to install new hardware. when i reconnected the cables back, i accidentally connected my USB cable to the firewire pins and the firewire cable to the usb pins. Then i charged my iphone. The iphone didn't turn on properly. I figured out what happened and fixed it. Now I can't charge my iphone using the USB port on PC at all. It goes the same for charging through wall electrical outlet.

Anyone knows what is going on? My firmware is 1.1.4. Unlocked via ziphone. T-mobile.
