The error you're getting is probably because Windows needs drivers for the COM port. I thought Windows 7 was fine, but maybe 64 bit isn't. Try following the Windows 8 instructions on this page and see if it helps...

Tried that a few times. I had it working a few weeks ago but it took me a day and a half to find some driver file that happened to work. Then my 3D printer showed up and I wanted to reset the windows computer to its factory state to get all the slow BS off of it. (my normal computer is a Chromebook) I sure wish I saved that file first because I can not duplicate whatever I did. Pulling my hair out! Its a HP laptop with Windows 7. Few years old..... Trying to re-flash with the network drivers.......


Download Stmicroelectronics Virtual Com Driver


Download File 🔥 https://fancli.com/2y3KrU 🔥



Use the instructions Gordon has supplied - however you will have to go in to device manager and access the "drivers" tab for the unknown com device and manually point to the file that is unzipped with the driver download, it was greyed out for me when I tried to update drivers via the "devices and printers" window.

If you can't flash Espruino, the problem is probably that the board you have uses a fake Prolific PL2303 chip for USB. Prolific got fed up with all the clones of their chip, and tweaked their drivers so that they don't support it.

Yeah I finally got it to work. There are a few issues I had. On these boards I had to use the TOP RIGHT usb port. When I downloaded the ST Flash Loader Demonstrator I was trying to get the STMicroelectronics com driver to work and it did not at all. The driver that worked best for me was this Prolific Driver. Its a Prolific Driver Version 3.2.0.0 and is dated at 7/31/2007

You have to manually update the Driver. Similar to this video


 although after that driver was installed on my Windows 7 computer it was named plainly as "USB-to-Serial" until I re-updated the Driver.

I see multiple people having this problem but not seen an answer why or a solution: The Virtual COM Port driver (1.4) is not working for Windows 10 users. I have the same problem. I download the Driver from:

However, what I don't understand is what exactly happened with the board/software/driver that caused the COM port to work. I've studied the 'USB F4 VCP Device' section of the PDF you've linked to but nothing there is making it entirely clear why this suddenly works.

I had a similar issue with the STM32L476 Virtual ComPort (VCP) not working properly, even though it seemed like all the drivers on Windows should have been in place after installing both ST-LINK004 and Atollic TrueSTUDIO 9.2.0.

Instead, I chose to wipe out all of those installed drivers and install the 64-bit Windows 8 VCP driver from the STSW-STM32102 package (even though the README says not to), and everything worked fine after that. I've written this up here, with before/after screenshots -- -virtual-com-port-issues/

I setup Octoprint on my laptop that happens to share the table with my Prusa Mini which is easier than moving my Pi, but have a single problem... Windows cannot find a driver for the mini. I've installed and reinstalled the latest Prusaslicer and installed the RAMBO driver package in the files (although I know that's technically for the MK3), but I cannot get it to install a driver and create a serial port, thus I cannot connect at all. The printer basically ignores it and acts like there's no USB plugged in. I've tested all the ports on my laptop, USB 2.0, USB 3.0, and a plethora of cables. Am I missing something? Trying Windows 7 Ultimate x64 for the additional information.

Yes, I'm connecting it to the microUSB port. I temporarily moved my Pi just to check to make sure it wasn't hardware related and Octoprint connected without issue. I'm going to be testing the STM32 drivers later today.

In device manager find the prusa mini in other devices. Right click on it then select update driver software. Then select browse my computer for driver software. Choose let me pick from a list of device drivers. Under the manufacturer list choose standard port type then under the model list choose communication port. Proceed until the process finishes. If that doesn't work then try installing the STM32 Virtual COM Port Driver mentioned here and redo the steps but choose STMicroelectronics under manufacturer and then STMicroelectronics Virtual COM Port under Model.

I have Nucleo STM32H743ZI board. I'm using CubeMX HAL (I tried several versions) and TrueStudio. "Virtual COM port" appearances in Windows 10 (I tried default Windows driver and ST driver) but I can not open port. My C# program write me "The parameter is incorrect" when I try open it:

Interesting, what C functions: "fopen("COM6", "r+"), fwrite, fgetc, fclose" - work in Windows 10 with FW1.4.0 without port configuration. Error of FW1.4.0 is in writing port parameters (baud, bits or others) and virtual COM port Windows driver arises exception if cannot write parameters into USB device

STMicroelectronics (NYSE: STM), has launched STPay-Mobile, a platform that simplifies virtualization of security-critical public transit ticketing and payment cards on smartphones and wearables.

First of all you should use the last BSP package for configuring the STM board. I am using stm cube with package stm32cube_fw_f3_v1.10. in addition update your compiler to the last version (as example Keil v5.26).

Give the USB driver in STM a proper time to configure as follow

 MX_USB_DEVICE_Init();

 /* USER CODE BEGIN 2 */

 HAL_Delay(2000);

Now in labview you will find your usb appear in NI MAX without any problem.

Notes

Update your NI VISA to the version 18 and installed driver.

I think the problem is with windows 10 default COM port driver. I was able to properly connect STM32 via USB on windows 7. To do so you just need to install driver for USB stm32 from ST company website.

I install the driver that ST brings which is STSW-009, to program via miniUSB, but it only flashed the code into the board it doesn't open any COM port when I plugged the miniUSB again or the micro-usb to the PC and reset the board. I'm programming with the Keil uvision 4 and using the API: 'CC256x STM32 Bluetopia SDK v4.0.2.2'

In the API's demo example says that "Once the code is flashed, connect the board to a PC using a miniUSB or microUSB cable. Once connected, wait for the driver to install. It will show up as MSP-EXP430F5438 USB - Serial Port(COM x), Tiva Virtual COM Port (COM x), XDS110 Class Application/User UART (COM x) for MSP432, under Ports (COM & LPT) in the Device manager."

It turned out to be a problem with the driver, my first tests with the laser were on my laptop which I installed the drivers specified by Ortur but then I moved it to my studio and the desktop there installed a windows driver I installed the proper driver and the problem seems to have gone away.

And then the next hurdle is getting the Arduino IDE to recognize the board. From Seeed the board will enumerate as a virtual COM port VID 0483 PID 5740, and if you open the serial monitor it shows that it is running Espruino firmware.

This took me a while to sort out as well. At first I recommend using the Arduino IDE for the serial monitor - you just have to close and re-open the IDE. The reason is that not all serial monitors work with the virtual COM for some reason (Termite did not). SSCOM did work, but is not 100% in English.

Description: Hi Bryn, On Win10, windows native driver is introduced for USB CDC driver. ST does not provide the CDC class driver for WIN10. Here is an article from Microsoft about USB CDC driver. -us/windows-hardware/drivers/usbcon/usb-driver-installation-based-on-compatible-ids To connect to host PC, the firmware on MCU has to support USB CDC device. This is an open question if MCU firmware support USB CDC. I would suggest you to contact your vendor for technical support. ST is not the right window for customized firmware support. Regards, Bossen WU

I may need to delete the DFU driver in order to get back the default driver for virtual Com port. Today, when switching from DFU mode to VCP mode, the VCP driver is not found. I have not seen any control within Device Manager that provides capability to hide or show inactive or disabled devices. I will search for one now you indicate it may exist.

My current working hypothesis is that my uploading of example sketch has somehow changed the USB signature of the device. The lack of a battery due to broken connector may also be involved.

If you are already having problems please read the addendums first to remove old or non-functioning drivers. It is important to have them cleaned up and installed the appropriate drivers first before you plug in the board!

Extract the zip file and start the Setup. After a successful installation you will find all necessary files and drivers in subfolders of the STM program folder. C:\Program Files (x86)\STMicroelectronics\Software\

Cannot get cleanflight to recognise the board. It will flash in DFU but afterwards will not connect. Updated drivers and tried Zadig. Starting to wonder if I have a faulty board, but its more likely me doing something wrong. Any help would be appreciated.

Do you get the error message within cleanflight saying failed to open serial port? If so then it sounds like a application/driver/PC setting. As this usually happens when an application does not release the serial port. Have you installed the Virtual COM port drivers from this link - STSW-STM32102 - STM32 Virtual COM Port Driver - STMicroelectronics 2351a5e196
