windows 10 does not discover DVD device

This drive that plugs into USB does not appear in Device manager but as a separate line item

-Initio Combo Device Class

    Initio Default Controller

also, there is no entry under the "USB Bus controllers" list.

To correct that:

De-activate and desinstall the "Initio Default Controller" and the drivers.

Unplug the DVD from the USB port - then power off the PC.

Plug the DVD - and restart the PC.

It should be OK now. It is present in Windows explorer with a drive letter.

In the device manager:
there is now an entry for Mass storage controller under the "USB bus controllers" list, and a new line item for device "DVD/CD-ROM readers"
