Glossary
Default Pipe: The message pipe created by the USB System Software to pass control and status information
between the host and a USB device’s endpoint zero.
Device: A logical or physical entity that performs a function. The actual entity described depends on the context of
the reference. At the lowest level, “device” may refer to a single hardware component, as in a memory device. At a
higher level, it may refer to a collection of hardware components that perform a particular function, such as a USB
interface device. At an even higher level, device may refer to the function performed by an entity attached to the
USB; for example, a data/FAX modem device. Devices may be physical, electrical, addressable, and logical. When
used as a non-specific reference, a USB device is either a hub or a function.
Device Address: A seven-bit value representing the address of a device on the USB. The device address is the
default address (00H) when the USB device is first powered or the device is reset. Devices are assigned a unique
device address by the USB System Software.
Device Endpoint: A uniquely addressable portion of a USB device that is the source or sink of information in a
communication flow between the host and device. See also endpoint address.
Device Resources: Resources provided by USB devices, such as buffer space and endpoints. See also Host
Resources and Universal Serial Bus Resources.
Device Software: Software that is responsible for using a USB device. This software may or may not also be
responsible for configuring the device for use.
DMA: Direct Memory Access
Downstream: The direction of data flow from the host or away from the host. A downstream port is the port on a
hub electrically farthest from the host that generates downstream data traffic from the hub. Downstream ports
receive upstream data traffic.
DQPSK: Differential Quadrature Phase Shift Keying a modulation technique used in TDMA.
Driver: When referring to hardware, an I/O pad that drives an external load. When referring to software, a program
responsible for interfacing to a hardware device, that is, a device driver.
DSP: Digital Signal Processing
DSTN Passive LCD Panel.
Dual band mobile phone: A phone that supports both analog and digital technologies by picking up analog signals
when digital signals fade. Most mobile phones are not dual-band.
DWORD: Double word. A data element that is two words (i.e., four bytes or 32 bits) in size.
Dynamic Insertion and Removal: The ability to attach and remove devices while the host is in operation.
E2PROM: See Electrically Erasable Programmable Read Only Memory.
EAV: End of active video
EDGE: Enhanced Data GSM Environment. A faster version of the GSM standard. It is faster because it can carry
messages using broadband networks that employ more bandwidth than standard GSM networks.
EEPROM: See Electrically Erasable Programmable Read Only Memory.
Electrically Erasable Programmable Read Only Memory (EEPROM): Non-volatile re-writable memory
storage technology.
