# Host-to-Host Connections
Unlike USB 2.0, the new standard will allow for two host devices to be connected directly with a USB 3.0 crossover cable. This new cable features the typical Type-A connectors on each end but with a new internal wiring.
USB 3.0 Type-A Connector Detail
The Crossover cable
1. omits the Vbus, D+ and D- wires
2. cross-routes the SuperSpeed transmit and receive connections.
This crossover cable is designed for debugging and host-to-host applications and will not cause damage if plugged into a USB 2.0 port.
# Cable Max Length
The new maximum length will be 3 meters for USB 3.0 cables (using 26 AWG internal wires) which is down from 5 meters for USB 2.0 cables. You will be able to extend this maximum length by inserting a hub or repeater between the two cables.
