[9fans] More USB audio

[Jack Johnson]

Excuse the spam.  I was poking through my junk snail mail and came
across these, thought the price was decent:

Just in case someone is looking.  I haven't tried these, so don't know
if they're supported, but they're cheap enough for an experiment and
Turtle Beach usually has darned good quality.

That's that outfit form York, Pennsylvania I believe.  We were fans of
them when I was a teenager and selling this stuff out of Electronics
Boutique.  :-)

I'm thinking I'll get one of these regardless of functionality with
Plan 9.  They were, at one time, SB16 compatible.

That also reminds me.  I sort of passed a torch of sorts with that
OHCI USB adapter support in Plan 9 due to a lack of time.  Anyone know
what's going on there or if it's worth it since I guess USB2 support
should probably work in a degraded UHCI mode?

no, the auxiliary controller can be either UHCI or OHCI.
you always need two slightly cooperating USB drivers now.
i know, it's pathetic, but all the new things strive to
fit in well to the original PC model.

I'd be interested in seeing whatever you produced, as would Charles, I
imagine.  I think there's USB 2 support in my future.

I produced little to nothing of use... In fact I kept having false
starts, then eventually a hard disk failure and before I even bothered
restarting again I had given over the same advice that was given to me
to someone who had a student who wanted to work on this at CMU.

I haven't checked to see if anything ever came of this though.

No work is currently in progress here at CMU (sorry).

Ok thanks for letting us know!

I had lost that email and couldn't sufficiently search it.  I thought
it might be you.  I remember it was from almost a year ago.

I'm not going to lie.  I'm probably one of the least experienced
people on this list to try to write any kind of hardware device
drivers, and, quite frankly, I didn't find reading the USB OHCI
specifications to be encouraging for a beginner.

Maybe I should try to write a parallel port driver first or something,
just to get the hang of the interfaces.

Err, no Plan 9 USB OHCI work.

We got one ath the labs.  Plugged it into Plan 9. It works.  It
actually outputs a lot of oomph into my headset.  Nice
device.

44100 or 48000 Hz, 16-bit stereo.  Has mute & volume control.

Awesome, now I wonder if it will work hosted through Parallels on a
Mac (it's supposed to allow for USB devices to be shared into the
managed OS...)

The Plan 9 USB driver can only use UHCI devices (i.e., Pentium and USB 1.0).

In sources/contrib/miller/usb/audio I've put a modified usbaudio which
works with the Griffin iMic - another small(ish) usb audio adapter, which
can record as well as play back.

Before I submit this as as a patch, I'd be grateful to anyone who could
try it with other usb audio devices, to check whether I've broken anything.

Thanks.
