    Anyone want a USB sound card + serial interface/Sirius interface in a box?

    I've been thinking of making a board that consists of the following:

    -- A USB hub chip
    -- A sound IC, probably the TI PCM2903B. Note that this part has an SPDIF input and output, which is nice.
    -- An RS232-type serial interface IC, probably the FTDI FT232R. Besides a regular old DB-9 connector (with the appropriate level converters), it'd also have a mini-DIN connector wired up such that you could directly plug in the various Sirius docks and radios that use that connector (e.g., SCVDOC1, the SCH1, etc.) with the serial lines going to the FT232R and the audio lines going to the PCM2903B.
    -- Two standard USB A connectors (...since the USB hub will have 4 ports, and the sound IC and RS232 IC will use up two of them).

    Note that all of the parts above were specifically chosen so that they're natively supported under both Windows and Linux. Also, the entire thing is powered via USB, although I'd probably have the option for additional power input if you wanted to hang full-power (500mA) devices off of the additional two USB ports.

    There's really nothing new here -- this is actually just taking some of the stuff that, e.g., Mitch on rush2112.com and others have done and sticking it all on one board for the sake of making somewhat cleaner/smaller installations. Particularly for connection between a carputer and a Sirius dock, this seems like it'd be the bee's knees...

    Does anyone else think this would be a useful device? Am I missing some really useful device that should also be part of such a board?

    Thanks for looking... I'll certainly be rather more motivated to do this if it's not just going to be a one-off for myself!

    I've been trying to bribe Mitch to build something like this to control both the Xm and BoomzBox with audio over USB for both for over a year.
    HARDWARE: Fujitsu Stylistic ST5111w/WiFi and dock, internal Hitachi 500G HD, external 1TB HD, Sierra Wireless Aircard 550, DVD-RW, BoomzBox HD radio, XM Commander, Delorme GPS, Saitek X-52 Pro joystick, BluSoleil Bluetooth, TPMS, FB, Elm327

    As far as I can tell, the BoomzBox is essentially a pairing of Mitch's box with an FTDI serial converter IC along with an audio IC with an off-the-shelf HD tuner box -- along with the nice software he's written as well, of course.

    What are you currently using for XM? The XMD2 interface?

    I have an XmD1000 and the TimeTrax interface. Sound is thru Fm wired to my headunit for stereo and directly into the mic line on the tablet. I would gladly give up the interface if I could get a way of receiving Audio over USB that RR recognizes and doesn't interfere with the BoomzBox, or my Logitech QuickCam Orbit's audio over USB.

    I have to deal with the limitations of using a TabletPC and the number 1 limitation is no stereo line in. I like the idea of mitch's UAS-4 paired with his audio over USB for the BoomzBox, but when I mentioned including a custom controller for the xm and boomzbox all in one package (or even as a modular UAS-4 with Audio over USB package with plug and play modules for visteon, boomzbox, sirius, Ipod, xm, etc.) I guess he saw no market for it and never bothered.

    If you just use a generic USB "sound card" (something that'll show up in regular Windows mixer/volume control applet) and connect its line or mic input to the XMD1000's audio input, is there a problem? I think I'm missing something here regarding either just what devices RideRunner recognizes (I would think any regular Windows sound cards...) and what might interfere with BoomzBox or your webcam (shouldn't really be anything...)?

    The two I've tried had PID conflicts with existing equipment. I do have 11 USB devices running with two existing Audio over USB sources too.

    RideRunner and BoomzBox require specifying USB devices via PID and hence won't let you have more than one soundcard (or serial interface) with the same PID? That sounds pretty poor -- Windows itself will let you plug in multiple sound cards as you like with the same PID; it tracks them by the serial number that (most) all USB devices have. (The FTDI serial bridge ICs all do, and I think the TI sound ICs sound... although I suppose there's no guarantee the product manufacturers actually program them...)

    One could definitely take a bog standard USB sound card, modify its PID, and the corresponding .INF file to still get Windows to "do the right thing." It's a hack, certainly, but if that's what it takes...

    course not, rr dont give a sh**t about the sound device
    and neiether does boomzbox

    windows can handle many devices with the same PID too

    Gizmo, windows xp does make it hard to manage audio devices...
    cause they all named the same thing...
    in vista/win7, users can name them anything they like

    but... for your xm/boomzbox thing...i have the solution for you... we could mod your boomzbox interface, and put in a 3.5mm jacks, that could go to the uas4
    so all you would need is a uas4
    then you can send your xm audio to the uas4, which its out would feed into the boomzbox hd's audio codec
