USB Type-C 10-foot Charging Cables

The USB 3.0 Promoter Group has announced that the next version of the USB Specification is coming soon: USB 3.2

It promises a doubling of the data rate of USB 3.1, with Gen 1 cables doubling speed from 5gbps to 10gbps, and Gen 2 cables doubling from 10gbps to 20gbps.

The basic premise of USB 3.2 is fairly simple: A Full-Featured USB Type-C cable has 15 wires, 8 of which are SuperSpeed wires. When operating in USB 3.1 Gen 1 or Gen 2 modes, only 4 of those wires are used right now. The other 4 may be assigned to an Alternate Mode like DisplayPort, but when used for USB-only operations, they are dormant.

USB 3.2 will double the bandwidth by using all 8 wires for USB in cases where both sides can support it and aren't using the other 4 wires for an alternate mode.
