Hello All,

 

I have developed a product that has a usb cdc device. It works fine when it's connected to a PC with the driver provided by ATMEL (file "atmel_devices_cdc.inf"). Now, a client wants to have its name in Device Manager for the COM port created by our product. We have tried to change strings "ATMEL_CDC_ASF_EXAMPLE=", but it didn't worked!

 

We are using ATSAM4LC2A.

 

Any one has clue how to change name of a CDC device shown in Device Manager of Windows. Currently, I am using Windows 10 pro.

 

Thanks in advance.

 

Regards,

Pandurang

You’ve hijackedtwo threads about something unrelated to your question and on top of that - in a completely wrong forum!
Delete the existing reference to the inf file. Failing that, Change the vid/pid and alter the inf file to suit.

Hi Kartman,

 

How to delete existing reference to the inf file?

BTW,

Changing VID and PID may solve the issue, but I think in that way, there will be no indication of ATMEL as well as CDC class used....

Windows 10 may cache the data for a given vid/pid. So chosing a different vid/pid will prove/disprove this. Google how to remove usb references. I’ve not done it with Win10.

By posting in the correct set of Forums that deal with your SAM versus the AVRs that are discussed here?

You can put lipstick on a pig, but it is still a pig.

I've never met a pig I didn't like, as long as you have some salt and pepper.

But is it anything to do with the SAM (or AVR) - or is it all just Windows stuff ... ?

  1. How to properly post source code - see: https://www.avrfreaks.net/comment... - also how to properly include images/pictures
  2. "Garbage" characters on a serial terminal are (almost?) invariably due to wrong baud rate - see: https://learn.sparkfun.com/tutorials/serial-communication
  3. Wrong baud rate is usually due to not running at the speed you thought; check by blinking a LED to see if you get the speed you expected
