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 ...
USB Attached SCSI (UAS) or USB Attached SCSI Protocol (UASP) is a computer protocol used to move data to and from USB storage devices such as hard drives (HDDs), solid-state drives (SSDs), and thumb drives. UAS depends on the USB protocol, and uses the standard SCSI command set.
Still, they were quickly replaced by the thinner Micro-USB connectors (Micro-A, Micro-B, Micro-AB). The Type-C connector, also known as USB-C, is not exclusive to USB, is the only current standard for USB, is required for USB4, and is required by other standards, including modern DisplayPort and Thunderbolt.
When the current hardware state is unknown to the CPU it can only put it into a known state by sending a new command, which may result in the state changing. [4] [5] To alleviate this difficulty, the content of the WOM may be mirrored by the CPU in the regular memory. [6]
The USB OTG and Embedded Host Supplement to the USB 2.0 specification introduced three new communication protocols: . Attach Detection Protocol (ADP): Allows an OTG device, embedded host or USB device to determine attachment status in the absence of power on the USB bus, enabling both insertion-based behavior and the capability to display attachment status.
The USB Implementers Forum states it does not support any connector used by other standards, hence such 'combo' ports are to be used at one's own risk. [ 1 ] [ contradictory ] As of 2011 [update] the organization responsible for the SATA specification, SATA-IO (Serial ATA International Organization), is working to define the eSATAp specification.

The 24-pin double-sided connector provides four power–ground pairs, two differential pairs for USB 2.0 data (though only one pair is implemented in a USB-C cable), four pairs for SuperSpeed data bus (only two pairs are used in USB 3.1 mode), two "sideband use" pins, V CONN +5 V power for active cables, and a configuration pin for cable ...
