Problem
The Green “VCC-ON”
LED is not on
AVRUSBKey does not
work
The AT90USB cannot be
programmed
Reason
No power supply
The AVR JTAG ICE
probe is not
connected
The memory lock bits
are programmed
The fuse bits are
wrongly programmed
Solution
Verify the power supply source (check
battery charge or USB connection).
Connect the JTAG ICE 10-PIN header to
the correct AVRUSBKey JTAG header
(page 13)
Erase the memory before programming
with JTAG ICE.
Check the fuse bits with JTAG ICE
Force bootloader execution with HWB
under reset.
Can not connect to
AVR Studio does not
detect the AVR JTAG
USB bootloader
Serial/USB cable is
not connected, or
power is off
USB bootloader erased after a JTAG
debugging session: reprogram the USB
bootloader with JTAG.
Connect serial cable to RS232 (STK500 -
AVR ISP) and check power connections
Connect serial cable to USB (JATG ICE
MKII, AVR ISPmkIIl) and check power
connections
Disable other programs that are using
ICE.
PC COM port is in
PC COM port.
use
Change PC COM port

AVR Studio does not
detect COM port.
Disable COM port auto-detection in AVR
Studio file menu. Force COM port to
correct COM port
