Typical Connection
AT91SAM9263
USB Handling is done through several layers as follows:
Figure 42-4. Board Schematic to Interface UHP Device Controller
As device connection is automatically detected by the USB host port logic, a pull-down must be
connected on DP and DM on the board. Otherwise the USB host permanently detects a device
connection on this port.
A termination serial resistor must be connected to HDP and HDM. The resistor value is defined
in the electrical specification of the product (R

• Host controller hardware and serial engine: Transmits and receives USB data on the bus.
• Host controller driver: Drives the Host controller hardware and handles the USB protocol.
• USB Bus driver and hub driver: Handles USB commands and enumeration. Offers a
