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).
In practice, the cable to the USB device counts as one of the six cables, reducing the maximum total length. If the USB 2.0 five-meter limit is not long enough for your needs, you can purchase one or more USB hubs or special cables. There are two types of hubs: powered and unpowered.
