Hi, I have the Rolands TD-30 edrum module that includes a USB sound card in it. The card lists but no capture or recording devices work, although they are listed. I am new to audio device drivers and for that reason need some guidance to contribute to such driver. A full log can be found at: www.alsa-project.org/db/?f=e1a28cbd7e9f1201d3b0cbe44d8ec1908272a1d4 Looking forward to ear from you. Best regards, Cupertino Miranda
