Do not waste your time. The problem is in the SD CARD that is in the interface. I had the same problem and solved it. Programming the sd card for KTAG and KESS is a very difficult process that can not be done by everyone. There are two options 1. that somebody who knows, do - can program a new sd card or other option to buy SD CARD I found on interenet aliexpress.

Did you use ksuite 2.23?
If you have Kess with 2.47, you cannot use KTag with this version.
Try with 2.23.
