A Chromecast stick plugged into the HDMI port of a TV. The cable attached to the other end is the USB power supply. In the mid-to-late 2010s, the dongle form factor was extended to digital media players with a small, stick-like form factor—such as Chromecast and Fire TV Stick—that are designed to plug directly into an HDMI port on a television or AV receiver (powered via Micro USB ...
There are potential weaknesses in the implementation of the protocol between the dongle and the copy-controlled software. For example, a simple implementation might define a function to check for the dongle's presence, returning "true" or "false" accordingly, but the dongle requirement can be easily circumvented by modifying the software to always answer "true".
A double entendre on the word "dongle" was overheard at a Python Conference (PyCon) programmers' convention on March 17, 2013, which led to two people being fired and a denial-of-service attack. History

Comparison of legacy USB connector plugs, omitting the current standard Type-C plugs. Unlike other data buses (such as Ethernet), USB connections are directed; a host device has "downstream" facing ports that connect to the "upstream" facing ports of devices.
USB OTG is a part of a supplement [2] to the Universal Serial Bus (USB) 2.0 specification originally agreed upon in late 2001 and later revised. [3] The latest version of the supplement also defines behavior for an Embedded Host which has targeted abilities and the same USB Standard-A port used by PCs.
While PS3 and Wii wireless controllers use Bluetooth for connectivity (and can be used with Bluetooth-equipped personal computers with appropriate software), Xbox 360 wireless accessories communicate over a proprietary 2.4 GHz protocol.
Ethernet over USB is the use of a USB link as a part of an Ethernet network, resulting in an Ethernet connection over USB (instead of e.g. PCI or PCIe).. USB over Ethernet (also called USB over Network or USB over IP) is a system to share USB-based devices over Ethernet, Wi-Fi, or the Internet, allowing access to devices over a network.
