Prepare:
1. USB wire 
2. VoCore


Step 1:
Cut the USB wire in the middle. We use red and black wires.


Clean up the USB wire.(not necessary).Tape again. :)


Step 2:
Connect VoCore to the wire, and connect USB to computer.


Now it works, then you can find VoCore in your computer AP list.
Rest please read http://vonger.cn/?p=1536.

Note:
1. Some computers USB power supply is not stable, that might cause VoCore failed to reboot. MacBook, ThinkPad do not have such issue. From report, some Dell PC might have such issue.
2. Clean up is not necessary, but better to do if you want to use your USB wire in long term. :)
