Well, this is the DIY forum... As far as I can see, I need to:
1- Find a place for this board, it could be just on top of the original board, the unit is tall enought, and the board seems to be flat.
2- Connect the 4 USB wires from the original connector, to those 4 holes in this PCB next to the USB connector, perhaps with a short piece of shielded wire, scrapped from some broken mouse cable.
3- connect the "SPDIF" output, those 2 holes I see in this board, to the SPDIF input in th eoriginal board, with a piece of MIC shielded wire...
4- disconnect the power going to the shorted USB section on the original board, or remove the ICs.
It seems doable
, the unit will look like original from the outside, and I don't mess with EEPROM things that I don't understand...
I'm not sure if I need to connect those "DATA" connections on the right of the pict.. Aren't this "USB to SPDIF" intended just to get USB input and send the output to that SPDIF connector?
