USB Subsystem

The protocol stack of the Universal Serial Bus (USB) device driver for the AIX® operating system consists of several drivers that communicate with each other in a layered fashion. These layers of drivers in the USB subsystem work together to support the attachment of a range of USB devices, such as flash drives, removable disk drive (RDX), tape, keyboard, mouse, speakers, and optical devices (for example, CD-ROM, CD-R, CD-RW, DVD-R, DVD-RW, and DVD-RAM).
