-====== How to fix a USB-ISP programmer and make it work with Arduino IDE on Linux ======
+====== How to fix a USB-ISP programmer and make it work as USBasp with Arduino IDE on Linux ======
 ===== Introduction =====
-I was tired of having bare PCB boards and wires all over the place, so I decided to order a USB programmer in a brightly colored metal case. The device I ordered was described as **"Aluminum shell USB ISP USBISP USBASP ASP Programmer for 51 ATMEL AVR WIN7 64 (Random color)"** shown below.
+Although I do not usually program chips, because I prefer to use complete modules, mainly for utilizing their USB port as a user interface, I happened to work on a few projects with a bare ATtiny85, which requires a programmer. I managed with a custom programmer, built on an Arduino Nano loaded with ''the ArduinoISP'' sketch. But as you all know, you never program once. Actually, I estimate that for program beutifications, minor adjustments etc. I program at least 5 times, and this, after the program is fully debugged!!! That is a lot of work, even for a single project.

-Googling the name of the manufacturer **"zhifengsoft"** as well as **"usb-isp"**, a ton of information came through, regarding the case. 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.

 Luckily, I did not have to re-invent the wheel because there has been a lot of excellent work. I decided to publish this article because:

-The controller inside my USB-ISP is an ATmega88. As found online, other models have an ATmega8. Just remember it when you construct the parameters at the commands below.

-Be extra cautious about the numbering of the connector pins. Usually, there will be an arrow imprinted on the connector that will mark pin number 1. This photo will help:

-After taking it out, I noticed that it contains an ATMega88 running at a 12 MHz crystal and the PCB states that it is **MX-U2BLSP-V5.00**, probably mimicking MX-USBISP-V5.00 of another manufacturer. Notice also a 0 Ohm resistor, which is the source of our troubles.
