Last night, I wanted to show the problem to a friend and I brought my kobo and my thread to her home. We tried to connect it to her computer and his work. I made the same test on the computer to my job today and there too it worked. I'm speechless. I really don't understand anymore, because at home I still have the problem on my main computer and my personal laptop (I retry again after I return home yesterday).
Tonight, I try this time to connect on the usb ports on the back. Nope.
And I try the safe mode too. No success
