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.
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)?
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?

SiLabs have already distributed this signed driver package for CDC on Windows,
You'll find it in DK (STK) examples in Simplicity Studio
The INF file defines these VID/PIDs for CDC
silabs-cdc.cat defines this OSAttr
2:5.00 = Windows 2K
2:5.1 = Windows XP
2:5.2 = Windows Server 2003
2:6.0 = Windows Vista and Windows Server 2008
2:6.1 =Windows 7 / Win Server 2k8
2:6.2 =Windows8 / Win Server 2k12
@Tsuneo: thank you. That worked.
