I have installed a usb traffic sniffer, to log all data to/from my AK8802 noname device.
The tool I have chosen is SniffUSB 2.0, available from:
www DOT pcausa DOT com/Utilities/UsbSnoop/default.htm
The resultant output is extremely verbose, thus would just clutter the board.
So, I will post links to formatted dumps, hosted on my home server.
Maybe we can figure out what should be different for AK8802 USB init...
p.s.: Admins, please consider allowing me to post URL's before the 7 day triage...
