USB Dual Role replaces USB On-The-GoTo USB or Not to USB: A USB IP Blog - Eric Huang, SynopsysMay. 07, 2018 |
As product makers move from USB 3.0 to USB 3.1 (and soon USB 3.2), they also move to USB Type-C. With Type-C, this means the connector is the same on all products. PCs and phones. Media players (remember those) and cameras and flash drives.
So no more A, micro-B, or micro-AB connectors. Only Type-C
Consumers can buy just one cable, and use it for everything. No more mixes of different cables.
Phones can be dual role devices (DRD). A DRD can be either a host or a device.
