This is a multi-part message in MIME format. --Boundary_(ID_/sbVHj3EuU7uIcvm6oNp4g) Content-type: text/plain; charset=US-ASCII Content-transfer-encoding: 7BIT Now that I have learned how to make udesc_dump work, I tried it on an older gadget that I have laying around. It is an "USB audio Phono PreAmp" from Pinnacle (it was included with the windows software "Steinerg Clean Plus" which was on sale sometime ago). According to the documentation, the hardware will work as a USB soundcard as well (yes, it has a line out jack in addition to the RCA phono inputs). With uhid, it is detected as: uhid0: Burr-Brown from TI USB Audio CODEC, rev 1.10/1.00, addr 3, iclass 1/1 Without uhid, it detects as: ugen0: Burr-Brown from TI USB Audio CODEC, rev 1.10/1.00, addr 2 And 'udesc_dump /dev/ugen0' output is attached. -- Regards, Torfinn Ingolfsen, Norway --Boundary_(ID_/sbVHj3EuU7uIcvm6oNp4g) Content-type: text/plain; name=pinnacle_preamp_udesc.txt
