+Mainteant, si on essaie de programmer de désactiver debugWire :
+<file.sh>
+avrdude -c jtag2isp  -P usb:070000004DAA  -p t85 -U hfuse:w:0xdf:m
+</file>
+On obtient le message suivant :
+<file.sh>
+avrdude: jtagmkII_setparm(): bad response to set parameter command: RSP_FAILED
+avrdude: jtagmkII_getsync(): ISP activation failed, trying debugWire
+avrdude: Target prepared for ISP, signed off.
+avrdude: Please restart avrdude without power-cycling the target.
+avrdude done.  Thank you.
+</file>
+<note important>AVRDUDE a désactiver provisoirement debugWire, il ne faut pas redémarrer la processeur</note>
+On peut donc relancer la commande pour programmer le fusible hfuse.
