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).
If a USB device needs to be connected to a computer but the distance is further than the maximum length of the cable, there are a few solutions to extend to connection. For a shorter distance that needs to be reached, a USB hub can be connected to the USB port and placed as far away from the computer as the hub's USB connection line is. Any devices can be connected to the USB hub using a 3 to 5 meter long USB cable.
