After installing latest 6.1 M2 software I noticed that adapter's software version was not updated. I have removed the software and the adapter from devide manager using an option to remove the driver as well and reinstalled 6.1 M2. Now I see adapter's driver as ever older one.
What should be the adapter driver version for DL-165? I got 5.6.31854 while core DL software installed is 6.1.36848
