Hi all, I’m newbie in here.
My friend gave me the Sub37 with this problem:
- Computer are not recognized it (Mac/Win).
- Blank Lcd.
- All Led are lit.
Almost One year I emaled Moog Service, they have good replied, they only suggested with 'Seat and Reseat the ribbon cable " and still not working.
Then I find/ read this :

I think It the same problem with mine ,crashed Usb Driver and Firmware.
Is Anyone have JTAG Files (HEX)for Sub37 ?
*ps : I’m repair tech, I already success repaired Minimoog, etc. And I’m familiar with Programmer Tools thing. 
Pardon for my English.
Thank You
