Went to work today. Called an allergist to schedule an appointment. Had dinner with Patrick, and then we came back here so he could show me his OpenGL based gravity simulation.
No new progress on au0828. I need to recompile the Ubuntu kernel so I can add some printk() and dump_stack() calls to figure out who is jamming arbitrary usb commands onto the bus (it seems pretty clear it is *not the au0828 driver, and I believe it is probably the snd-usb-audio driver).
I'm too tired to do anything productive tonight. I thought perhaps I would watch a little TV, but I think I'm just going to go to sleep.
