I hope you can still use your reader for reading, even though you did install KSM.
Just to give you some information on he current situation: I can now control the reader from the web browser of my pc. With the Windows inbuilt speech recognition I can press the bottoms of the web page when I use Microsoft Edge as browser. I have to establish the connection via usbnet. I know, I said we can use in the beginning wifi instead of usbnet. But it turned out, I have currently a problem with wifi on my kobo, and do not want to spend time with this problem now. In the end we would have to change to usbnet anyway.
Therefore, I would like to ask you to prepare your pc for usbnet. Unfortunately, I cannot give you step by step instructions (I did it myself only once.) Take as a starter
this post. There is no need for hurry. I will need some time to prepare the other things anyway.
