Hello everybody,
There is no switch in the ISP unit. One has to open the covers and there is a provision on the PCB to solder a two pin jumper (taken out of berg connector). Once the soldering is done, plug in the jumper and power up the unit and after a short while the jumper can be removed. Now the unit ready to program.
Note: the power to the ISP is drawn from the target board and through the ISP programming connector. While the ISP unit is being upgraded, the MISO,MOSI and other pins must not be connected to the target board. Therefore use only power and ground pins of this ISP connector to power up the ISP unit. I do agree that this is a bit of a long procedure, but thats the system is designed.

There is no button in the AVRISP. In the docs somewhere it says to power the
AVRISP( the led comes on, cycles colors and settles on green I think). You
should not connect it to your target as this usually mungs communications
with the micro's in the ISP. Once the AVRISP is idle(green status led),
clock OK to program it.
This is a real pain and your lucky. In my experience, a lot of the time, the
ISP will mung code in it's secondary MCU and become dead. Atmel has an
appnote on recovering but I have yet to be successful.
This message will happen every time you update studio, a choice I think a
big mistake. The funcinality should have been left in AVRStudio and the ISP
code left frozen.
Hope this helps.

Let us know how you make out.

Where is the 'program' button on the AVRISP?
