If the following device name is shown, the USB driver is already installed and the computer recognizes the MICRO/I.
• HG2G-5F, HG3G/4G: IDEC USB CDC ACM. (XXXX) (XXXX is the port name.)
• HG2G-5S: Silicon Labs CP210x USB to UART Bridge (XXXX) (XXXX is the port name.)
• HG2F: NVUSB Device
HG3G HG2G-5F HG2G-5S HG2G-S HG4G HG1F HG2F HG2S HG3F HG4F
• The device name will disappear if the USB cable is disconnected or the MICRO/I power is turned off.
• When the MICRO/I power is turned on and the USB cable is connected, the words Unknown Device or
a “?” may appear in place of the device name, indicating the computer may not be recognizing the USB
driver correctly. Disconnect the USB cable and turn the MICRO/I power off. Then turn the MICRO/I
power on again and connect the USB cable to check that the computer recognizes the USB driver. If the
computer still does not recognize the USB driver, uninstall it from the Device Manager and reinstall it.
