Yes it's a USB mouse. I have a decent 5V linear supply here that I can try. Do I need to desolder the USB power pin to try out the external PSU?

Yes you could desolder the power pin on the USB jack and attach the outside power supply, but per the spec sheet, the HOST pin of the PCM2707 is supposed to go high when attached to the bus. That will happen before as the way I did the board, it is attached to power (with no switching). So it may or may not work. I would try some other USB ports first. Also curious what kind of amp you are running and at waht gain? |

I could be wrong but I can't imagine why they would ship everything for free just because something is backordered. |

Host detection during self-powered operation (connect to VBUS). |
