It seems that the device is working along with the Windows program [[https://www.electrodragon.com/w/8051 | ProgISP]] and is not recognized by ''avrdude'', the program which uploads code to Arduino and other Atmel micro-controllers. | + | Googling the name of the manufacturer **"zhifengsoft"** as well as **"usb-isp"**, a ton of information came through.

| The original purpose was to purchase a cheap programmer to avoid the clutter of having an Arduino Nano and a bunch of cables, and to avoid wiring manually every time I wished to program an MCU.

As I said at the beginning of this article, this is just for hobbyist fun. Did not expect anything more at a price of less than two euros. |
