Yes, I've been able to mix the thing properly now. Thanks.

Only differences were fairly cosmetic: atrophy:~/alsa# diff uhci usb-uhci 15c15 < iProduct 2 USB UHCI-alt Root Hub --- > iProduct 2 USB UHCI Root Hub 50c50 < Bus 001 Device 002: ID 041e:3000 Creative Labs --- > Bus 001 Device 005: ID 041e:3000 Creative Labs I had to disconnect my minihub and connect only the extigy by itself in order to use the usb-uhci driver. I normally only use uhci, as I need to use a usb mouse and the extigy, which requires a hub that doesnt like usb-uhci. Given the output above, I'm probably doing something rather silly again with regards to some kind of random compatibility issue. I am still running the mixer with the debug hack you put in. -mark ------------------------------------------------------- This sf.net email is sponsored by: viaVerio will pay you up to $1,000 for every account that you consolidate with us. http://ad.doubleclick.net/clk;4749864;7604308;v? http://www.viaverio.com/consolidator/osdn.cfm _______________________________________________ Alsa-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/alsa-devel
