Switching to DFU mode is no longer possible #16
Description
For reasons unknown to me I can no longer switch to DFU mode. The Levithan is installed in a working printer and no other USB devices are connected
Here is the dmesg output after pressing the boot and reset buttons as described in the instructions:
