A USB 2.0 Cable should have 4 cables. They are the Vcc, Data+, Data- and Ground.
Will only disconnecting the Vcc OR Ground Wires damage the Connected Device or the Data Wires?
I currently have a USB SD Card reader that I like to Disconnect and Connect. The reader is mounted on the table, so to disconnect the reader, I would plug off the USB Cable connecting the reader and the computer.
To solve this problem, I would like to place a switch in the power lines, but I wonder if this will break the device since the Data cables are still connected but the power lines are disconnected.
Any answer will be Appreciated. Thanks in Advanced
