Usb cdc serial port driver

SiLabs USB-CDC (virtual COM port) driver redistributable?

Has Energy Micro provided any suitable. INF files to make the USB CDC implementation easier on Windows 7? 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. Windows 10 no longer requires a special. I use the driver from 11th january from the last version of the kit, with a EZR32LG device tested ok on other platforms.

Many times before i had created a software for F CPU and CDC USB output. Now i need to reuse this project, but my actual Win7 64bit computers do not like any of approximately 25 CDC installations which i does in the last 2 weeks. I have with great happyness red this thread about signed CDC Silabs drivers. I try to install Simplicity but this section in the path described before in the 4 version does not exist! Can someone tell me the place who can i find the needed Win7 64bit drivers for this "CDC ACM example device"???

Please dont tell me "search" - i do it long time before i goes again here. Hope, i must not wait so long, as the man in previous post. Problem - i do not have this directories in my Simplicity installation. I mean, i have installed Simplicity only to get this file, but i do not need it and do not installed nothing else as the Simplicity itself and all questions from Simplicity i answered with no.

I have directly Keil evaluation studio especialy for this one processor and need to correct any things in this CDC project. After it i deinstall the Simplicity, i do not need to spend such many place on my laptop if i do not realy need it. I think If you update the SS to include the EFM32 SDK, you could see the directory that include the CDC driver.

But this driver told me - on Win7 64bit - the same like the 20 drivers before:. If you have the EFM32 board and program it with the usbdcomposite example code and then you could also try to pick the driver for the device after connect it to PC like below link said:.

USB serial driver (Usbser.sys)

Hi all and thanks for the input in here, quite a lot has help to even get these drivers installed. My issue is now that the drivers are installed i am still having issues with my device being recognised in windows 8. This is the same on 3 identical laptops. But anything less than windows 10 this is not being picked up, even after successfully installing the drivers. I know windows 10 utilises the usbser.

As a basis for my source I used the usbdcdc example for the DK Everything works fine, but installing the USB virtual COM port driver EFMCdc. 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.

Does anybody know how I create an end-user friendly installer for the driver? Is it possible to sign the driver. Perhaps these sites can give you some clues on how to proceed: I too used the EFM32LG-DK source, target is currently a STK but will be my own hardware in about a weeks time when the PCBs come back from assembly. 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. I had to do all the steps in the readme. What is the exact error message you get, screenshot maybe? Did you do all the steps in the readme. Have you tried zadig from the libwdi package? It creates self- signed drivers for you that you should be able to install. 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? Presumably it should be very easy for Energy Micro to supply a suitable. 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. Again, this capability should be available from Energy Micro. Energy Micro does sublicense USB PIDs under their VID. You have to submit an application. HI Guys I found this tip for windows regarding unsigned driver. Many thanks, best regards, Feri. Anyway I attached the package and try if it works on your side.
