  2. USB hardware - Wikipedia

    en.wikipedia.org/wiki/USB_hardware

    A number of extensions to the USB Specifications have progressively further increased the maximum allowable V_BUS voltage: starting with 6.0 V with USB BC 1.2, [43] to 21.5 V with USB PD 2.0 [44] and 50.9 V with USB PD 3.1, [44] while still maintaining backwards compatibility with USB 2.0 by requiring various forms of handshake before ...

  3. USB 3.0 - Wikipedia

    en.wikipedia.org/wiki/USB_3.0

    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 .

  4. WebUSB - Wikipedia

    en.wikipedia.org/wiki/WebUSB

    The threat surface of a USB however is bi-directional and a malicious peripheral device could attack the host. An infected edge device cannot easily be mitigated by WebUSB API's. In many device configurations trusted USB ports are used to deliver firmware upgrades and a malicious edge device could grant attackers persistence in a system. [11] [4]

  5. USB flash drive - Wikipedia

    en.wikipedia.org/wiki/USB_flash_drive

    The USB connector may be protected by a removable cap or by retracting into the body of the drive, although it is not likely to be damaged if unprotected. Most flash drives use a standard type-A USB connection allowing connection with a port on a personal computer, but drives for other interfaces also exist (e.g. micro-USB and USB-C ports).

    In addition to network repositories, compact discs and other storage media (USB keydrive, hard disks...) can be used as well, using apt-cdrom [16] or adding file:/ URI [17] to the source list file. apt-cdrom can specify a folder other than a CD-ROM, using the -d option (i.e. a hard disk or a USB keydrive). The Debian CDs available for download ...

  7. Chromebook - Wikipedia

    en.wikipedia.org/wiki/Chromebook

    The device's USB port is capable of supporting a keyboard, mouse, Ethernet adapter, or USB storage, but not a printer, as ChromeOS offers no print stack. [124] Adding further hardware outside of the previously mentioned items will likely cause problems with the operating system's "self knowing" security model. [125]

  8. lspci - Wikipedia

    en.wikipedia.org/wiki/Lspci

    lsusb [3] is a similar command for USB buses and devices. To make use of all the features of this program, a system needs to use Linux kernel which supports the /proc/bus/usb interface (e.g., Linux kernel 2.3.15 or newer). Example output on a Linux system:

  9. Intelligent Platform Management Interface - Wikipedia

    en.wikipedia.org/wiki/Intelligent_Platform...

    Using a standardized interface and protocol allows systems-management software based on IPMI to manage multiple, disparate servers. As a message-based, hardware-level interface specification, IPMI operates independently of the operating system (OS) to allow administrators to manage a system remotely in the absence of an operating system or of the system management software.
