Starterware/AM3358: Problems with serial communication and Windows 10

Part Number: AM3358

Tool/software: Starterware

Hi,

I'm running a StarterWare 2 based application on an BBB which makes use of a USB serial interface implementation based on the StarterWare example and by using a .inf-File which is similar to "usb_dev_serial.inf" which is available in "tools" directory. Of course VID and PID have been changed accordingly.

This works well with all Windows-versions up to 7 (8.x was never tested) and also with all Linux variants. But now with Windows 10 there is a problem:

  • opening of the serial interface from Windows 10 often fails, simple repeating of the procedure then is successful latest after 10 tries
  • sometimes an already opened connection seem to be corrupted some times, means there is no more communication possible, host application needs to be closed, device needs to be restarted - but after this, the same COM-port is available again, Windows does not change numbering

So: does anybody else have such problems? Are there any changes necessary in INF-file or in USB serial interface code to make it work with Windows 10?

Thanks!
