USB Schematic
Posted: 13 Mar 2009, 17:06pm - Friday[gallery] When my friend's Card Reader goes something wrong, I tried to fix it and found that the wires are pulled out. So I found the solution (shown below) to resold the wires back into its position.
| Pin one side | Signal | Description | Pin other side |
| 1 | USB Vcc (Vbus) | usually RED, wire should be 20-28 AWG | 1 |
| 2 | USB Data - | usually WHITE, wire should be 28 AWG | 2 |
| 3 | USB Data + | usually GREEN, wire should be 28 AWG | 3 |
| 4 | GND | usually BLACK, wire should be 20-28 AWG | 4 |
