hi, Support for USB controllers and hubs is still incomplete. Basically in the following cases isochronous transfers (used by audio devices) don't work. - ehci controllers with hubs between a usb-1.1 device and the controller doesn't work (bug causes packet corruption). It somewhat works if there's only one device on the hub and no full-duplex is used. - xhci doesn't work at all for audio. according to your dmesg: uhub0 at usb0 "Intel xHCI root hub" rev 3.00/1.00 addr 1 uhub3 at uhub0 port 10 "GenesysLogic USB2.0 Hub" rev 2.00/48.46 addr 5 uhub4 at uhub3 port 4 "Genesys Logic USB2.0 Hub" rev 2.00/32.98 addr 6 uaudio0 at uhub4 port 3 configuration 1 interface 0 "CONEXANT the device is attached to xhci. So try to find a port of the ehci root hub, if you can't then try at least to find a port connected to ehci and disable full-duplex (add "-m play" before "-f rsnd/1"). Possibly disable xhci (try "boot -c" on the boot prompt), in which case it will show as ehci. -- Alexandre
