+Employing firmware on a fresh china arduino leonardo clone:
+
+step 1: Connect avrisp2 or another isp programmer
+
+step 2: set fuses for this application:
+avrdude -p atmega32u4 -c avrisp2 -P usb -U lfuse:w:0x5e:m -U hfuse:w:0xd9:m -U efuse:w:0xf3:m 
+
+explanation:
+(contains following features)
+  Divide clock by 8 internally; [CKDIV8=0]
+  Serial program downloading (SPI) enabled; [SPIEN=0]
+  Hardware Boot Enable; [HWBE=0]
+  
+  DISABLED JTAG!
+
+step 3: for faster development flash the atmel stock bootloader ... which you find in ../atmel_stock_bootloader
+
+step 4: connect board usb to your PC, use stock bootloader to flash cooler device firmware:
+make program_bootloader
+
+step 5: EMTSCHEU
