Posted on: 03.05.2011 by Monty Strauder
Hey Guys! First i have to say the Midi fighter is a really great and cool tool! I love him very much! The midi fighter arrived last week and works great! Today in the morning he worked! I wanted to use him in the evening, and ... he dident worked! I plug in the USB Cable and all lights are blue but the top-left-second is dark! i can push every button - nothing happens! I tried a reset with a peace of wire! i tried to go to the boot mode - didnt work, my pc didnt say "Hey u plugged in a Midi fighter" - i plug in the cable - lights on - nothing happens... :eek: :eek:

i hope everyone can help me!

p.s. sorry for my teenie english

I dont touching on the top of the Chip, not on the Pins! It seems like the AT didnt work correct! Yes, i tried all methods of the community ! Nothing works! Today i will looking for the crystal... and the USB D+ and D- ... if this is okay, i will change the AT!

Have also been remeasured if the reset signal is applied to pin 24 of the AT90USB162, all right! As I said, it is not recognized as an usb device and nothing responds! I freak out!

05.05.2011		Hey guys! I have some News! I wanted to measure the Clock on the Chrystal with an oscilloscope and then! ZACK BOOM! All LED's a dark, then, the first Lights up, then the Second, then the third! my pc found a new USB device called "midi fighter"! Then i go back with my test prod and usb device isnt connected! Nothing works again... I knew it sounds funny, but i changed the chrystal and all works! later i try to go in boot mode for reflashing!

Also, have you reset the MidiFighter yet? That might do the trick
