If the USB host is restarted, the enumeration process is repeated for all connected devices. The host controller directs traffic flow to devices, so no USB device can transfer any data on the bus without an explicit request from the host controller. In USB 2.0, the host controller polls the bus for traffic, usually in a round-robin fashion. The ...
California's SB-327 Information privacy: connected devices "would require a manufacturer of a connected device, as those terms are defined, to equip the device with a reasonable security feature or features that are appropriate to the nature and function of the device, appropriate to the information it may collect, contain, or transmit, and ...
A physical network node is an electronic device that is attached to a network, and is capable of creating, receiving, or transmitting information over a communication channel. [1] In data communication, a physical network node may either be data communication equipment (such as a modem , hub , bridge or switch ) or data terminal equipment (such ...
To allow for voltage drops, the voltage at the host port, hub port, and device are specified to be at least 4.75 V, 4.4 V, and 4.35 V respectively by USB 2.0 for low-power devices, [a] but must be at least 4.75 V at all locations for high-power [b] devices (however, high-power devices are required to operate as a low-powered device so that they ...
A smart device is an electronic device, generally connected to other devices or networks via different wireless protocols (such as Bluetooth, Zigbee, near-field communication, Wi-Fi, NearLink, Li-Fi, or 5G) that can operate to some extent interactively and autonomously.
A four-port "long cable" "external box" USB hub A four-port "compact design" USB hub: upstream and downstream ports shown. A USB hub is a device that expands a single Universal Serial Bus (USB) port into several so that there are more ports available to connect devices to a host system, similar to a power strip.
The Linux kernel has supported USB mass-storage devices since version 2.3.47 [3] (2001, backported to kernel 2.2.18 [4]).This support includes quirks and silicon/firmware bug workarounds as well as additional functionality for devices and controllers (vendor-enabled functions such as ATA command pass-through for ATA-USB bridges, used for S.M.A.R.T. or temperature monitoring, controlling the ...
