The USB mass storage device class (also known as USB MSC or UMS) is a set of computing communications protocols, specifically a USB Device Class, defined by the USB Implementers Forum that makes a USB device accessible to a host computing device and enables file transfers between the host and the USB device. To a host, the USB device acts as an ...
For the Bluetooth Low Energy stack, according to Bluetooth 4.0 a special set of profiles applies. A host operating system can expose a basic set of profiles (namely OBEX, HID and Audio Sink) and manufacturers can add additional profiles to their drivers and stack to enhance what their Bluetooth devices can do. Devices such as mobile phones can ...
The host stack is generally implemented as part of an operating system, or as an installable package on top of an operating system. For integrated devices such as Bluetooth headsets, the host stack and controller stack can be run on the same microprocessor to reduce mass production costs; this is known as a hostless system.
General 3.5 mm computer headsets come with two 3.5 mm connectors: one connecting to the microphone jack and one connecting to the headphone/speaker jack of the computer. 3.5 mm computer headsets connect to the computer via a sound card, which converts the digital signal of the computer to an analog signal for the headset. USB computer headsets ...
For example, when you use a mobile phone with a Bluetooth headset, the phone uses SDP to determine which Bluetooth profiles the headset can use (Headset Profile, Hands Free Profile (HFP), Advanced Audio Distribution Profile (A2DP) etc.) and the protocol multiplexer settings needed for the phone to connect to the headset using each of them.
USB On-The-Go (USB OTG or just OTG) is a specification first used in late 2001 that allows USB devices, such as tablets or smartphones, to also act as a host, allowing other USB devices, such as USB flash drives, digital cameras, mouse or keyboards, to be attached to them. Use of USB OTG allows devices to switch back and forth between the roles ...
The latest version ASIO 2.3 introduced monitoring for dropouts in the audio stream. [4] ASIO bypasses the normal audio path from a user application through layers of intermediary operating system software so that an application connects directly to the sound card hardware. Each layer that is bypassed means a reduction in latency (the delay ...
As of 2013, Media Agnostic USB (MA USB) is a specification being developed by the USB Implementers Forum. It is intended to enable communication using the Universal Serial Bus (USB) protocol to be performed over a wide range of physical communication media, including WiFi and WiGig wireless networks.
