==== Dual-role USB connections ====
USB bridge cables have become less important with USB dual-role-device capabilities introduced with the USB 3.1 specification. Under the most recent specifications, USB supports most scenarios connecting systems directly with a Type-C cable. For the capability to work, however, connected systems must support role-switching. Dual-role capabilities requires there be ''two'' controllers within the system, as well as a ''role controller''. While this can be expected in a mobile platform such as a tablet or a phone, desktop PCs and laptops often will not support dual roles.<ref>{{cite web |url=https://superuser.com/questions/1080002/usb-3-1-type-c-host-to-host |title=USB 3.1 - Type-C Host to Host |website=superuser.com |access-date=21 July 2021 |archive-date=14 October 2021 |archive-url=https://web.archive.org/web/20211014022330/https://superuser.com/questions/1080002/usb-3-1-type-c-host-to-host |url-status=live }}</ref>
