I have seen and read threads related to usb not working due to broken usb ports, but I have a bit different situation. I was making a home made usb charger... but seems that I had reversed the polarity and damaged/destroyed my USB port's connection with outer world.

Dr_frost_dk suggested me to connect the fuse terminals as fuse may have been wasted. I broke the fuse and connected the two terminals with solder itself... Still the usb doesnt seem to work.

Does anyone know what the problem maybe? or what else could have been damaged due to that reverse polarity. Also any alternatives to data transfer as well as chargin.

I would be happy if at least I could charge using the same port. For data transfer I can use scp, bluetooth etc etc.
