How I will connect my electronic piano to my PC

Hi,
I have this error every time I try to connect my electronic piano to my PC. The thing is that my Windows is up to date, all softwares are updated, and drivers also are updated, including this one. Please guys help me to connect this and tell me why I have this error? What is the main cause of this error?
Thank you!
