Should there be a windows driver to use the virtual com port in CDC examples? My Windows 7 box detects the UC3C-EK as unknown device?
Is there a driver package that needs to be installed ?
Thanks /// Carl
It is available at the location
asf->common->services->usb->class->cdc->device->atmel_devices_cdc.inf in the AVR software framework.
I wish that information was written in every example or the documentation of each kit that requires that driver.
I have found this file located at C:\window\inf but it still shows as unknown device.
I am not able to find that path using Atmel Studio 6.
Did you ever get your virtual com port working? I am still not able to get this working with my AT32UC3C-EK.
Here is the update:
I download ASF version 2.9 from the following link:
After extracting the files the USB driver for the UC3C-EK board will be in the following path:
I used the driver here \..\ASF\asf-standalone-archive-2.9.0\asf-2.9.0\avr32\services\usb\_asf_v1\class\cdc\examples\driver
I then had to edit the .inf file to use the PID of 2310 instead of 2307. I found the currently used PID by checking in device manager.
The virtual com port is working now!
