If you are trying to return the AVRISPmkII and purchase the Pololu AVR ISP just because it costs less, you may as well just keep the AVRISPmkII.  You will spend the difference in price just on shipping charges alone.  However, if you are convinced that your AVRISPmkII is defective, that is a different issue.

I assume since you are still in the market for a programmer that your AVRISPmkII is still giving you problems.  Have you tried to MANUALLY upgrade the firmware?  The procedure is outlined in this document:

http://www.atmel.com/dyn/resources/prod_documents/AVRISPmkII_UG.pdf

Seems to me like I was able to revive an AVRISPmkII that exhibited the same "orange blinking light" behavior that you described earlier in this thread.  Since the unit I repaired had previously been used by someone else, I'm uncertain how it arrived at that state.  Anyhow, the manual firmware upgrade may be worth a try at this point.

HTH,

Yeah I got the mine from DigiKey for $35.

Well since I'm just doing this as a hobby.
So I don't know when I'll use this again after this project.
So affordable equals dirt cheap LOL :p

So for the basic use I have I guess the Pololu AVR ISP should do what I need just fine?

Hopefully DigiKey will give me a refund and not just a credit.

Thanks for the input.

You can beat that price: 

AVR ISP II is about $35 at Digikey. 
Pololu AVR ISP is $20 (emulates AVR ISP II with other cool stuff). 
AVR STK500 is $80 at Digikey both parallel and ISP programmer. 

Those are all what I consider very affordable.

This is very similar to what I was having. I could programme the device
using ISP mode from the JTAG ICE MKII but could not do it from the ISP.

 

I re-flashed it and it started working again. No idea why it was like that
in the first place as I had never used it from new.

 

Good luck

Dave.
