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.

Raul Gutierrez Saenz Pdf To Excel. 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.

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. 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.

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? 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.

This example project use the EFM32 USB Device protocol stack and implements an USB CDC based virtual COM port. UART1 on the DK is used as the physical COM port. Any data sent to the virtual CDC COM port is transmitted on UART1. Any data received on UART1 is transmitted to. USB CDC and VirtualCom driver on Windows.
