Kit Operation

2. After connecting the development board to the host, wait for the Windows drivers to install. If the

drivers do not install automatically, follow the steps in the “Appendix” on page 52 to manually

install the drivers.

3. After the driver installation is complete, observe the blue LED (LED2). If the development board

is connected to a USB 3.0 port, the blue LED (LED2) blinks. If the development board is

connected to a USB 2.0 port, the blue LED (LED2) stays ON. If the development board is

connected to a USB 1.1 port, the blue LED (LED2) stays OFF.

Note This is a useful way to speed-test USB ports on a PC, where the USB operating speed is

not always obvious. For example, some desktop PCs have the telltale blue plastic inserts (which

are supposed to indicate USB 3.0) in both front and rear USB receptacles. Nevertheless, the

front-panel receptacles often operate only at a USB 2.0 rate (480 Mbps).

4. Take a look at the USB Control Center. It should appear as shown in Figure 3-4. The USB

Control Center detects the development board, which is named Cypress FX3 USB

StreamerExample Device. This appears as the heading in a device tree in the left panel.

With the Descriptor Info tab selected, expand the device tree nodes and click on the various

components – Device, Configuration, Interface, and so on. Notice that the descriptor information

changes according to what is highlighted in the device tree. This illustrates the context-sensitive

nature of the USB Control Center – you should select an item in the device tree before conducting a

particular USB operation.
