Efm32 Usb Cdc Serial Port Device Driver

May 23, 2018 - I've also downloaded and installed the USB driver from here. I think if you download the AN0065SW, you could see a CDC driver in host. Driver is installed and recognized, as well as what port it's attached to,. Korg mini kaoss pad 2 manual español.

I am trying to get the usbcomposite example for the EMF32WG990256 STK3800 working on my windows 7 computer. I'm running the example in IAR. I'm just trying to get the drivers to install correctly at this point.

The directions in the example description are attached. When I run the example, a 'host' folder is not included in the directory so I went and grabbed the 'host' folder from a usbvud example online and dropped it into the usbcomposite directory. After setting up the directory and compiling the project onto the board I disconnected the j-link cable, switched the board from debug to USB and plugged in the USB. The device comes up as an 'Unkown Device' in Device Manager. I tried right-clicking and installing drivers manually where I direct the device to the 'host' folder. Windows then gives me an error saying 'Windows could not find the driver for your device.' I tried moving to a simpler example and using usbvud just to try and get the USB driver working again.

When I compile and download usbvud the board shows up in Device Manager as 'EFM32 USB Vendor Unique LED Device' but it still has a yellow exclamation mark by it. When I try to point this device to the 'host' folder, windows gives me the same error saying 'Windows could not find the driver for your device.' Is the 'host' folder referred to in the directions supposed to be automatically included in the project directory?

If so what would prevent that from being created and is there a place where I can grab the entire usbcomposite project directory? If not, should the 'host' folder from the usbvud be sufficient to get the drives to use EFM32-LedApp.exe? I'm not experienced with drivers and don't know what I may have missed in this process. Could someone point me in the right direction to solve the driver problem and get the examples working? Hi As far as I know after you plug in the device (with composite F/W) to PC USB port you could see items as attached picture in device manager.

The Ledapp should work if you see the EFM32 Vendor Unique device under libusb-win32 devices. This is based on liusb-win32 driver. The Silicon Labs CDC Serial port under ports(COM & LPT) should be the signed driver pointed out by Stephen. If you use the usbdvud sample you should only see the EFM32 Vendor Unique device showed up.
