I am currently in the works of programming my Satan GH60. This is my first build and i am very confused on how to flash a keyboard layout onto it. Immediately after plugging it in, it showed up as ATm32U4DFU with no driver installed. I then used Zadig to load winusb onto it, however i am realizing now that i could have just use easyAVR to build it and load on the layout. I have tried to this now using easyAVR and installing by going in to "Build and Reprogram", then selecting upload using flip (which i have version 3.4.7 installed) and then pressing the button on the back of my keyboard and then lastly pressing run. When I do this I get a message saying it has failed, the prompt says "AtLibUsbDfu.dll not found". Hoping someone would know where i went wrong and could send me in the right direction. I thought it could be due to installing WinUSB first as now whenever I go into device manager and try to change it into the Flip usb drivers it says that windows believes it has the best drivers and won't let me switch it, perhaps that could be whats preventing easyAVR and flip from being able to install the layout?
