USBLSB

USBLSB refers to the Universal Serial Bus Local Storage Bus. It is a conceptual interface or standard that has been discussed in the context of how USB devices, particularly storage devices like flash drives and external hard drives, communicate with a host system. The idea behind USBLSB is to create a more streamlined and efficient way for the operating system and the storage device to interact, potentially by standardizing certain low-level commands and data transfer protocols beyond the typical USB Mass Storage Class.

While the term USBLSB itself is not a widely adopted or officially defined standard in the same way that USB 2.0 or USB 3.0 are, it represents a desire within the industry to simplify and enhance the performance and reliability of USB storage devices. Discussions around such concepts often aim to reduce overhead, improve error handling, and enable more advanced features. The implementation and success of any such standard would depend on widespread adoption by both hardware manufacturers and operating system developers. Currently, the USB Mass Storage Class driver is the primary mechanism used for most USB storage devices.
