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 ...
Additionally, xHCI simplifies the architecture needed to support a mixture of low-speed and high-speed devices, which streamlines the development of drivers and system software. xHCI marks a significant improvement over its predecessors, the Open Host Controller Interface (OHCI) and the Universal Host Controller Interface (UHCI), in several key ...
Windows Driver Frameworks (WDF, formerly Windows Driver Foundation), is a set of Microsoft tools and libraries that aid in the creation of device drivers for ...
Memory card readers, unlike smartphones, telephones and other devices, such as cameras and digital cameras, allow formatting in a file system other than FAT (FAT16, FAT32, exFAT) to NTFS in Windows, ext, ext2, ext3 in Linux or HFS, HFS + for Mac OS. Smartphones or other devices like cameras format them only in FAT.
Open Host Controller Interface (OHCI) [1] is an open standard.. Die shot of a VIA VT6307 Integrated Host Controller used for IEEE 1394A communication. When applied to an IEEE 1394 (also known as FireWire; i.LINK or Lynx) card, OHCI means that the card supports a standard interface to the PC and can be used by the OHCI IEEE 1394 drivers that come with all modern operating systems.
According to a USB-IF chairman, "at least 10 to 15 percent of the stated peak 60 MB/s (480 Mbit/s) of Hi-speed USB goes to overhead—the communication protocol between the card and the peripheral. Overhead is a component of all connectivity standards". [1] Tables illustrating the transfer limits are shown in Chapter 5 of the USB spec.
Drivers that may be vulnerable include those for WiFi and Bluetooth, [19] [20] gaming/graphics drivers, [21] and drivers for printers. [ 22 ] There is a lack of effective kernel vulnerability detection tools, especially for closed-source OSes such as Microsoft Windows [ 23 ] where the source code of the device drivers is mostly not public (open ...
In computing, a class driver is a type of hardware device driver that can operate a large number of different devices of a broadly similar type. Class drivers are very often used with USB based devices, which share the essential USB protocol in common, and devices with similar functionality can easily adopt common protocols.
