Tips for Heavily Oxidized Aluminum. First of all, determine the extent of oxidation on the aluminum surface. If it is determined that the surface is in relatively good shape, i.e. light oxidation, then skip this step and move on to polishing with Flitz.
Q1: How long of a cable can I use to connect my device? A1: In practice, the USB specification limits the length of a cable between full speed devices to 5 meters (a little under 16 feet 5 inches). For a low speed device the limit is 3 meters (9 feet 10 inches).
Another option would be to get a USB over Cat5 extender. These devices use Cat5e or Cat6 cable to extend your USB devices to distances of around 50 to 60 meters (around 150 to 200 feet). What makes these devices especially nice is that most modern homes already have Cat5e or Cat6 cable running to almost every room.
