You can connect Codey Rocky, mBot, HaloCode and other devices to mBlock 5 only after you agree to install the CH340 serial port driver. mBlock 5 uses the CH340 serial port driver. For macOS High Sierra 10.13 or later, kernel extensions can be installed only when users agree. If no "Allow" option is provided in step 3, go to step 4.Ĥ. After the preceding operation, mBlock 5 is supported to identify the serial port of your device. The system instructs you to restart the computer once again after you click to allow the installation of CH340.

Close such software as 360 security or computer housekeeper, and reinstall mBlock 5 again. If you can see the driver but mBlock 5 still fails to identify the serial port, the identification program of mBlock 5 may be blocked by the security software. If you can see the CH340 driver on Device Manager, mBlock 5 is supported to identity the serial port properly. Open Device Manager and check whether the CH340 driver is installed. The system may instruct you to restart your computer during installation. (Ensure that the USB interface of the computer works properly). Ensure that you have used a USB cable to connect your device to the computer and turned on the device. What can I do?Ĭause: The serial port driver is not successfully installed.ġ. mBlock 5 cannot identify the serial port after a device is connected to the computer. The information COM3 included in the parentheses is the serial port.Ģ.
Check the serial port of USB-SERIAL CH340. (2) Choose Device Manager in the window that appears. (1) Right-click My Computer (or Computer) and choose Manage. We can view the serial port in the device manager by performing the following steps: On Windows, when a hardware device is inserted into the computer, th system automatically identify the device and include it in the device manager.

How to check the serial port of a device on Windows? A message is displayed indicating that the pre-installation fails when I install the driver. The Windows Device Manager does not show the Port (Other device) option. After installing the CH340 driver on Windows 7 (not activated), I cannot see the corresponding serial port on Device Manager. The Windows 7 system displays a message indicating that the driver is installed, but the driver is shown with an exclamation mark on Device Manager and the serial port cannot be connected.

Recently I got a ESS32-CAM card and it contains the same Ch340 chip and it has worked fine even with the USB cable so I suspect that the ch340 designer released an updated design of the chip that meets the USB timing specs or maybe some aspects of the board design are adjusted to help make the timings.īottom line, unless you enjoy chasing down problems you will be better off buying the more expensive ftdi or other non-Chinese designed chips.MBlock 5 Webpage and mLink Quick Start Guide When I say I get it to work, all I have been able to do is install the wrap connector and get the adapter to talk to itself as verified with putty.
This would also explain why sometimes it will work after installing into a different USB connector on the PC since those timings can vary as well. Consequently if a chip designer is not careful about meeting USB timing specs then there will be situations when that chip will not work. From my work experience I know that the USB timings are very critical in order to maximize performance. However, if I use an extension USB cable most of the time it fails to work. I say this because I have noticed that if I plug my Ch340 board directly into my USB port it works. Next, it is apparent that the Ch340 design does not meet USB standards in the area of critical timings. After doing that I was able to solve the install failed problem. First thing to do is run/click the uninstall button. Since my last posting I have discovered some things that may help eliminate this problem.
