Quick Charge is a proprietary technology that can charge battery-powered devices, primarily mobile phones, at power levels exceeding the 7.5 watts (5 volts at 1.5 amps) supported by the USB BC 1.2 standard, using existing USB cables. The higher voltage available allows more power (watts) to be supplied through wires without excessive heating.
A flash drive, a typical USB mass-storage device An M.2 (2242) solid-state-drive connected into USB 3.0 adapter and connected to computer. The USB mass storage device class (MSC or UMS) standardizes connections to storage devices. At first intended for magnetic and optical drives, it has been extended to support flash drives and SD card readers.
ONFI produced specifications for standard interface to NAND flash chips. Version 1.0 of this specification was released on December 28, 2006, and made available at no cost from the ONFI web site. Samsung was still not a participant. [9] It specified: a standard physical interface for NAND flash in TSOP-48, WSOP-48, LGA-52, and BGA-63 packages
A variety of (non-USB) standards support charging devices faster than the USB Battery Charging standard. When a device doesn't recognize the faster-charging standard, generally the device and the charger fall back to the USB battery-charging standard of 5 V at 1.5 A (7.5 W).
USB 3.0 port provided by an ExpressCard-to-USB 3.0 adapter may be connected to a separately-powered USB 3.0 hub, with external devices connected to that USB 3.0 hub. On the motherboards of desktop PCs which have PCI Express (PCIe) slots (or the older PCI standard), USB 3.0 support can be added as a PCI Express expansion card .
This is especially beneficial for mobile devices with limited battery life, such as tablets and smartphones, as it helps to maximize power utilization and extend battery life. Streamlined Architecture: xHCI's architecture is designed to be simpler and more straightforward, reducing the complexity of driver development. In older architectures ...
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.
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 ...
