avrdude: Device signature = 0xffff07
avrdude: Expected signature for ATtiny44 is 1E 92 07

avrdude: Send: . [1b] . [10] . [00] . [03] . [0e] . [11] . [01] . [01] . [17]
avrdude: Recv: . [1b]
avrdude: Recv: . [10]
avrdude: Recv: . [00]
avrdude: Recv: . [02]
avrdude: Recv: . [0e]
avrdude: Recv: . [11]
avrdude: Recv: . [00]
avrdude: Recv: . [16]
