Hello, I write here with the hope that a user can help me more than the support service, I have had this problem for a long time and I have not found a solution, even writing to support, I do not think it is something of having to take the kemper to a place to repair, which is impossible for me because I do not live in a country where it is easy . The same problem that I have seen a lot around here, my Kemper does not read any USB key, I have tried many Keys, I am in a version that I cannot update from the rig manager, I have tried everything, the last thing I tried was to press the two buttons on page <+> and the message of unable to mount USB appears, with any USB key that I put in it, can someone help me? I have tried to format the USB key so that the kemper copies the two folders where I am going to paste the kaos.bin, formatting in fat32, nothing has worked, I read something about to paste the kaos.bin file directly in the root of the USB stick , but I do not understand
