# Universal Serial Bus
2.0
- Used for communication between a host and several devices that each provide functions
- Two modes:
- *host* - initiates the communication (usually a computer)
- *device* - receives and transmits data when the *host* requests it
- each device has a 7 bit address assigned upon connect
- maximum 127 devices connected to a USB host
- devices are interconnected using *hubs*
- USB devices tree

- can work as **host** or **device**, but not at the same time
- uses a differential line for transmission
- uses a 48 MHz clock
- maximum 16 endpoints (buffers)
- *IN* - from **device** to **host**
- *OUT* - from **host** to **device**
- endpoints 0 IN and OUT are used for control

# Device Organization
configuration, interfaces, endpoints
- a device can have multiple configurations
- for instance different functionality based on power consumption
- a configuration has multiple interfaces
- a device can perform multiple functions
- Debugger
- Serial Port
- each interface has multiple interfaces attached
- endpoints are used for data transfer
- maximum 16 endpoints, can be configured IN and OUT
- the device reports the descriptors in this order
