Pci Serial Port Driver

Hello,
I want to communicate with the EFM32 MCU over a USB/CDC connection. As a basis for my source I used the usbdcdc example for the DK3750.
Everything works fine, but installing the USB virtual COM port driver (EFM32-Cdc.inf) on Win7 is a mess.

  • Right mouse on the file and klicking Install results in an error.
  • If I use DeviceManager for installing the driver I get a big warning that the driver is not signed and shall not be installed.

For me as developer no problem. But not usable for end-users.
Does anybody know how I create an end-user friendly installer for the driver? Is it possible to sign the driver (.inf file)?
best regards,
Wolfgang

    Hi,
    I don't have any experience preparing user friendly driver packages, but I guess Microsoft's documentation would be the place to look.
    Perhaps these sites can give you some clues on how to proceed:
    Driver Package Installer
    Signing and Staging Device Drivers
    I see you've already found this, but for reference we have another topic on how to apply for a USB PID from Energy Micro:

  • I too used the EFM32LG-DK3650 source, target is currently a STK3600 but will be my own hardware in about a weeks time when the PCBs come back from assembly.
    BUT..
    I can't install the USB virtual COM port CDC driver as it says it isn't compatible with Windows 7 64 bit!
    This IS a major problem for me as unlike Wolfgang I am not a Windows developer and have no idea as to what to do next.
    Moving to another computer is NOT an option as all the machines I have access to are running Windows 7 64 bit.
    Any ideas?

  • Hi Susan,
    All our USB examples are developed and tested on windows 7 64 bit, I'm running 64bit myself and the examples are working. I had to do all the steps in the readme.txt file, including the reboot + F8 and do the 'Disable Driver Signature Enforcement' thing.
    What is the exact error message you get, screenshot maybe?
    Did you do all the steps in the readme.txt supplied with the cdc virtual com port example?

  • It's a shame that Microsoft can't get their act together on supporting standard USB class drivers without needing special drivers or INF files to be installed. With Linux it just works. Unfortunately that's no use when customers want Windows. The customer is always right. (When the customer is insufficiently right, they're no longer the customer.)

  • Off on other things now until Monday (my time is currently split 50/50 between two groups/projects).
    Also at another desk.. sitting in front of another computer. Joy!
    Thanks.
    Best,
    Susan.

  • Have you tried zadig from the libwdi package? It creates (self-)signed drivers for you that you should be able to install.

  • I've also run into this problem. After adapting the USB virtual serial port code from the sample project an0042_efm32_usb_uart_bootloader, Windows 7 could not find a device driver. Then after the Windows alert vanished Windows completely ignores the USB serial port ( even after disconnecting/reconnecting). After running a Ubuntu Linux VM in my Windows 7 machine the USB serial port communication works (with Linux, not Windows). Does Energy Micro provide a generic Windows 7 USB virtual serial port driver?
    Thanks

  • As I understand it, Windows 7 and 8 have a generic USB CDC driver, but what they don't have is a .INF file to configure it. That's often referred to as a driver, even though it really isn't. Presumably it should be very easy for Energy Micro to supply a suitable .INF file.

  • I am also working on a CDC project and having a signed driver installer would make the end-user's life much easier. I have used the Si Labs CP21xx USB to UART bridge chips in the past with much success. They provide a signed Win7 driver installer that can be easily executed by the end user. I want to use the USB functionality on the EM32 system to reduce component cost and increase flexibility.
    Energy Micro should be able to provide a similar solution for their USB enabled microcontrollers.
    In addition, SiLabs also provides the capability of letting customers use their VID for USB applications when the $2000 fee for a custom VID is not cost effective. They also sublease PIDs. Again, this capability should be available from Energy Micro.

  • Energy Micro does sublicense USB PIDs under their VID. You have to submit an application. See the details here: http://forum.energymicro.com/topic/59-how-can-i-obtain-a-usb-pid/

  • HI Guys I found this tip for windows regarding unsigned driver.

    It worked for me.



  • Has Energy Micro provided any suitable .INF files to make the USB CDC implementation easier on Windows 7? Having to change the signed/unsigned driver setting is far too complicated for an end user. If no updated drivers have been installed, has anyone found good workarounds to this problem? Does getting a PID from SiLabs solve this issue?


  • Does anyone have any information, if silicon Labs will issue a signed driver or not? It is not possible to install unsigned driver for many of our customers. Does anyone have any other suggestion about how to solve this?


  • [quote]if silicon Labs will issue a signed driver or not?[/quote]
    SiLabs have already distributed this signed driver package for CDC on Windows,
    - Silabs-CDC_Install.zip
    You'll find it in DK (STK) examples in Simplicity Studio
