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).
USB 3.0 - Breaking the Length Barrier. The new USB 3.0 standard has dramatically improved the connection between hosts and peripherals across the world. With its SuperSpeed data transfer rate of 5 Gbit/s and current delivery rates at 900 mA, USB 3.0 has improved upon and supplanted USB 2.0 in numerous applications. Despite these improvements in electrical performance, USB 3.0 is significantly limited by its shorter cable length requirement. In April 2013, an update to the USB-IF compliance for USB 3.0 standards restricted A male to B male cable lengths to three meters maximum.
