Designer Reference Manual
Since low-speed USB devices should be equipped with a captive
connection, the USB cable is fixed on the USB08 board (downstream
direction). In the upstream direction (PC/host side), the USB
connections are always type A. Therefore, the cable of the USB08 demo
board has a type A plug.
The connection of the demo board is made directly to the USB socket of
the PC or, as shown in the
Figure 1-1. Demo Board Connected to the USB Hub
The board supply current can be delivered by the USB connection.
Therefore, the jumper JP2, which is directly beside the USB cable, has
to be in the position Bus Powered. The jumper JP1-A (jumper block,
highest position) must be opened, which corresponds to the default
shipping configuration.
