Hello fine people,
I am, well, I was a lucky owner of an EMU0204 USB sound interface.
I used that to make many measurements with Spectralab, Arta and recently MultiInstruments.
That Interface WAS great.
One of these evening I found myself using a wrong USB-HUB power supply with 12V instead of 5V. The board of the 0204 broken up with a roasted plastic smell.
Does someone on the net knows where to find schematics or any useful stuff to try and repair the board?
I 'd apreciate any kind of help with this issue.
Thank You all.
Paolo.

I only recall seeing diyers preparing signal front-end circuitry schematics for 0204 and 0404, along with photos. It may be worthwhile you doing extensive google searches to look through the various threads that explore tweaking those models, especially the noisy power supply aspect in one channel of the 0404.
But I think you will need to reverse-engineer the USB port circuitry at least and do some basic fault-finding as to what parts have failed, and whether you can repair or bypass or disable/remove failed parts to see whether remaining circuitry is still functional (ie. to determine how extensive damage may be beyond the immediate USB interface). I'm sure others would benefit from any rough schematic you can provide.
