  1. Virtual COM Port problem


    I recently bought a laser etching device that uses STMicroelectronics Virtual COM Port driver. I downloaded and installed the driver, and I was able to get the driver to appear under Ports in the Device Manager. When I check the properties, I get "This device cannot start. Code 10 The specified request is not a valid operation for the target device." I have tried uninstall/reinstall and updating the driver. All the instructions from the manufacturer and videos on-line show this should be a simple task, Please help. Screen shot below.

  3. No USB Virtual Printer Ports

    When manually installing a printer, I cannot select a USB port because none exist. How do I get the virtual printer ports for USB001, USB002, USB003, etc. to appear in the list?

    I have read through many replies and I do NOT need to know how to manually add a printer. Creating a new port does nothing but give a name to something that doesn't exist.

    Also, I do NOT need information on updating my driver because I am using the generic/text only driver within Windows.

    If the ports don't appear the the port list, what do I have to do so that they will?

    Thanks

  4. Virtual COM Port problem

    Unable to install virtual com ports.

    Unable to install driver for virtual com ports. The installer says that the installation was successful but the comports do not appear in the Device Manager list. The specific software is SiliconLabs Dual CP210XUSB to UART Bridge Enhanced COM PORT.

    The SiliconLabs links were no help.
