ladies and gentlemen :
sorry, i would like to talk about something positive, but the purchase of a proclaimed USBasp programmer from a canadian company which doesn't match the USBasp specs and simply does NOT WORK brought us here to share our techie investigation.
-
we spent the time to analyze the layout of the device and drew up a schematic from it.
-
searched for a possible software which would work with it, found one, looked initially promising, but it still doesn't work
-
got really disappointed after all this work, to find out it looks like a bait and switch job from the vendor.
-
share the steps of this rocky road we took, so that you do not need to find out for yourself, the hard way.
-
recommend to compare the pics of the product advertised and the product showing up on your doorstep a week plus later, you might not remember how the details looked when you ordered it, cause you were too busy working.
-
just take our pics to compare your product against to identify a potential USBacp programmer which might not work with standard USBasp interface GUI apps.
on this webpage, dedicated to this USBasp clone you will be able to find out everything we were able to discover.
the whole story an more pics and schematics on our web page

this product seems only to work with an english GUI from a chinese software company "zhifengsoft.com", but we never really got it work with it.
so ... please look exactly if the product you get, matches the advertised pics and seems to perform as advertised ...
for us being new to the avr and arduion tools chain, we initially thought we were probably doing something wrong with the device ... but all we did wrong was to buy from the wrong vendor
this was a canadian site and seems a well established ebay seller advertising with the word USA right next to the product
we bought plenty from chinese vendors and luckily never had any bad experiences ... dx.com ... electrodragon.com
thanks for reading our story.
cheers, blue2u
