For reference, for other users searching this archive, it's a "Creative USB Sound Blaster Live! 24-bit External".=20 (http://creative.com/products/product.asp?category=3D1&subcategory=3D206&pr= oduct=3D10702&nav=3D2) I have added some inspection code to usb-mixer.c, which basically dumps all class specific USB interface descriptors.=20 My card got 2 x OUTPUT_TERMINAL, 2 x INPUT_TERMINAL, 2 x FEATURE_UNIT for the AudioControl class. But this doesn't make me any wiser. I wonder why the snd_usb_create_mixer code does only loop over the OUTPUT_TERMINAL class, even there is support code for all other types in the parse_audio_unit code, which is called subsequently by snd_usb_create_mixer. My aim is to have controls available for the Line-in mixer, both for recording and for direct re-mixing into the Main Out Plug. Is there a developer owning such a box, or anyone who can guess what I'm supposed to do with the additional AudioControl class controls?=20 Are there any tools that helps inspecting the USB device, or further dumping of class-specific content and/or inspection of the USB flow between a vmware hosted windows system and the linux host system? Thanks, What's the reason why Bug#995 is not available to the public? I'm getting access denied. Otherwise I would have put this message into the bugtracker. --=20 http://clemens.endorphin.org, for robots sp4mtrap@endorphin.org --=-d/1udmzgsqOnprFXRWPD Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.6 (GNU/Linux) iD8DBQBCJtotbjN8iSMYtrsRAvHXAKCF0Df1mn8HIAFH+iWD4YD2S3MhtwCcDd51 rVli9u25/vjcSNX6dop+RQ4= =iGDc -----END PGP SIGNATURE----- --=-d/1udmzgsqOnprFXRWPD-- ------------------------------------------------------- SF email is sponsored by - The IT Product Guide Read honest & candid reviews on hundreds of IT Products from real users.
