No USB detection.
Posted: Tue Jun 28, 2011 11:19 amOK. I am building my case for MD, so for the first time everything is connected (jacks, LCD, buttons). Since yesterday, my MD is not detected by any of my pcs. Things I tried:
1) Changed the USB cable
2) Changed the PIC 18F2450 with a 18F2550
3) Disconnected everything (jacks, buttons, LCD) in case the USB port power wasn't enough
4) Tested MD in 2 pcs
5) Reseted to default settings
The strange thing is that MD seems to work great. I mean, the VU on LCD works great everytime I hit a pad. But it doesn't show up to PC, not even as an unrecognized device. I have the latest firmware for Atmega, Synthex 2.5 board with pulldown resistor etc. I would love to have a midi synth around me to test the midi ports, but I don't. Any suggestions?
Problem Solved!!! One of the data cables going from the board to the usb socket was loose. Please lock this one Dmitri...
