I have a USB device which is recognized as a COM port on Windows 10, but in order to work, I must force it to use a custom device driver (not signed). This procedure works fine, but if I unplug this device and connect another sample, It's again recognized as a COM port (this didn't happened on Windows 7).

I already disabled driver signature check, and testing indicates that the port in which the device is connected doesn't matter:

  • A device for which I manually selected the driver can be connected to any USB port and it will work.
  • A device (same model) for which I let Windows install the driver, will always be detected as a COM port, no matter in which USB port I connect it.

Is there any way to tell Windows 10 to use the driver I want for every device having the same VID/PID, instead of the one built in one?

  • You are connecting it to the same port each time? You have disabled the feature that requires signed device drivers I presume? – Ramhound Jul 12 '16 at 18:35
  • Same port, yes. It's displaying a warning about the driver not being signed when I force the driver, but it works fine after that. The problem is that win doesn't use that driver after I plug another device – Vitor Jul 12 '16 at 18:49
  • I still don't know if have specifically enabled allowing unsigned drivers or not. – Ramhound Jul 12 '16 at 19:33
  • I did enabled unsigned drivers, as nothing would work without that. I followed the instructions from acer.custhelp.com/app/answers/detail/a_id/38289/~/… – Vitor Jul 13 '16 at 10:38

To temporarily prevent the driver from being reinstalled until a new driver fix is available, a troubleshooter is available that provides a user interface to hide and show Windows updates and drivers for Windows 10.
