In this instruction, the R55x0 USB console uses a Silicon Labs CP210x USB to UART Bridge Virtual COM Port driver, which may require configuration of drivers on your PC. You might use other equivalent driver if that works for you.
- Power on the R55x0 and wait approximately 30 seconds to allow it to boot up.
- Connect the USB cable to the R55x0 USB console port and your PC's USB port.
- Depending on the version of your PC's Windows OS, your PC should automatically detect the R55x0 as a new USB device and install the appropriate driver. Check to ensure that the driver is properly installed by inspecting Control Panel > Device Manager > Ports (COM & LPT), at which a “Silicon Labs CP210x USB to UART Bridge (COM7)” (or equivalent COM#) should appear without error. If the driver has not appeared or has errors, then proper drivers may be found at http://www.silabs.com/products/mcu/pages/usbtouartbridgevcpdrivers.aspx.
- With the USB to UART Bridge drivers installed, again take note of the COM port number that it has been assigned by inspecting Control Panel > Device Manager > Ports (COM & LPT).
