[9fans] VT6306 chip is for OHCI or UHCI?

[9fans] VT6306 chip is for OHCI or UHCI?

[Kenji Okamoto]

I got today a USB2.0/IEE1394 interface card probably Japanese local
card, named IFC-PCI7IU2, which is claimed by the user interface to be
VIA OHCI Compliant.   The card uses VT6306 and VT6212 chip.

I tested this card on my desktop machine, and Plan 9 recognized the
USB interface normally.   I'm now confused much.   The Plan 9's USB
driver is for UHCI programming interface.   Then, why this VT6306
card can be recognized by that Plan 9 driver?   Someone more familiar
with USB, please let me know what is going here...

Does it work too?  If it does, then I suspect the card also implements USB1
and UHCI for backward compatibility.

It's the problem.☺

I got a USB audio interface, too for that USB card, the name of which
is HCMI-106, named as 玄音(gen-on) probably Japanese local, too.
It's not included in your compatible list of course.

It has problem just now, getting the error message of
"Can't configure playout for 44000 or 48000 Hz".
However, I have now the audio hardware, and I think I can read your
codes with more reality.   If I get something better, I'll mail you.

I've had some struggles with this.  According to the specs, one sets the
playout speed by putting the number 44100 (or some other number of course)
in a control message to set speed.  I found a few devices with discrete speed
settings (the one you have has these) where, instead of writing the speed,
you have to write the number of the setting (i.e., 0, 1, 2, 3, ... or just 0 or 1
in your case).  I attempt both and, if both fail, I print that message.

I would try to ignore that message for now and see if it works at all

Thanks Sape for your kind comment.
This time, my case is at now, however, related to the number of
channels, 8 (7.1) for this case, but hard coded as 2 in the source.
After solving this, I may touch the problem you encountered.

By the way, I learned somewhat so far:

>desc 1.0 [12] 0x24: 1.1: Audio Input Terminal Descriptor

>Device can record from <unnamed>

This 0x201 must be microphone.

>desc 1.0 [12] 0x24: 1.1: Audio Input Terminal Descriptor
>	bTerminalId 5, wTerminalType 0x605 (<unnamed>), bAssocTerminal >0 bNrChannels 2, wChannelConfig 3, iChannelNames 0 iTerminal 0
>Device can record from <unnamed>

This 0x605 may be S/PDIF...  This device has S/PDIF input and output for
light connectors.   Unfortunately, this device has no CD input connector,
which may make me to forget internal DVD drive of the desk top?

Yep, in theory you can have mutiple input and multiple output audio streams.
I never went there; it's hard enough as it is.  FIguring out from the descriptors how
a device is configured is pure AI.  (proof below in what you just discovered :-)

Very possible.  I'll look in the standards docs tomorrow to see if I can find what
0x201 and 0x605 mean (probably they're undefined -- I must have typed the names
in for the ones that were defined).

Your device also has a mixer (if I remember a previous message correctly)
This may take a number of inputs or outputs and connect them together.

In my case, all the buf[0] to buf[2] values equal to zero from the returned value
from setupreply() in setspeed() in usbaudioctl.c.   This is strange to me.

I'll try.

I tried this, and got failed result.
Indeed, it went fine apparently, but the binded /dev/audioctl, /dev/audiostat
/dev/volume didn't work. ☺

I'll try more what is happening here.

Try writing to the appropriate /dev/usb?/?/ep?data.

It may be the case that the audio device isn't initialized properly because the
speed isn't set.  I've no idea what you have to do to get it set.

Anyway, if data gets consumed by /dev/usb?/?/ep?data, but no sounds happen,
then you may have to find out how to program the mixer or the selector.
You could time a
	cp pcm-file /dev/usb?/?/ep?data
to measure the data rate and verify whether the setting is 44100 or 48000.

(I'm just telling you what I did in the past to debug these devices).

Probably silently.  There is no such discription on the manual.

This card has following devices:

1106/3038      VIA VT82xxxxx UHCI USB1.1
1033/0035:    NEC USB PCI-USB OHCI
1033/00E0:    NEC USB2.0

So, the first device is now working.

And I bought USB sound device named HCMI-106, composed of only
one chip named CM106-F.

I have a serious problem how to set Adaptive USB Stream Out, or just reduse
that function to ordinal synchronous stream, say not 
desc 1.0 [9] 0x05: addr 0x06 attrib 0x09 maxpkt 768 interval 1ms [OUT] [Iso] [Adaptive]refresh 0 synchaddress 0
but just to
desc 1.0 [9] 0x05: addr 0x06 attrib 0x09 maxpkt 768 interval 1ms [OUT] [Iso] refresh 0 synchaddress 0

At last, no it doesn't work, just make a very short sound at once when
some sound data were put to /dev/audio.

If anyone has any comments on this result, please don't hesitate to mention
it.☺

Re: [9fans] VT6306 chip is for OHCI or UHCI?

[Kenji Okamoto]

After I summed-up the previous results, I noticed myself I may be doing
something very stupid.  Then, I set on the debug flag of the usb kernel,
and found the problem was not the endpoint is for Adaptive, but just on
the discrepacy of 2 channels or 8 channels.

The present debugging output of
term% usb/usbaudio -V -v 50 -d 0xf
was much improved, and I feel I may very close to the goal...

Anyway, revised results are as foloows, sorry evry one.

It's very far from here to the goal, if any.
I wonder why people want such many channels for audio listening.
This makes very complicated topology, and then, hard to code them, 
and I'm going to abandon it. got tired!

Re: [9fans] VT6306 chip is for OHCI or UHCI?

[Kenji Okamoto]

I got music from this CM106F chip USB audio device now!
I coundn't stop to write this here.  This is my summer vacation's
hacking result of this year.

I have still many things to be fixed, however, I think I got it
to make work for me.   Sound quality?  Not so good, better
than internal SB16 compatible card.☺

The device I'm using here is composed of only one chip
called CM106F, and connectors, which include S/PDIF
optical in/out, 2 mic input, a stereo line jack, three output
jacks for various speakers, and a jack for headphone, and
of course a USB connector.   The name of the device is
Kuro Sound(玄音) in Japan.  I don't know what is it called
outside.   However, you don't worry about it, because its
component is only a chip, called CM106F.

Kenji

PS. Sape, I'll send you my update soon.

a stereo line in jack

The box has four buttons on its top face, volume +/-
and Play/Rec Mute.

Hmm, it's not so fair.  This USB audio device does better
job for a piano music, because it makes too large sound
suddenly.   Even in such music, USB audio seems to do 
better job to me.   I don't want to compare it with my
home multi-channels tube audio system though.☺

Ah, I've just out of listening Glenn Gould of 1981.
I felt he is really great! from this USB audio device!
Audio is very nice, because we can meet 1981 Gould,
young Paul, and John Lennon!
Ilike this device now.

>three output
>jacks for various speakers

Those are four, Front(2), Rear(2), Soround(2), Center/SuperWoofer.
Probably, I'll never use them other than two Front speakers...
I may have spoken too much...

Today, I tried strings music, Mozart's string quartet by Alban berg, 
and also found I can listen this kind of music from this device.
I have been not fond of doing such on internal PC sound
device ( in ths case, Via's for Linux).

Now trying Uchida and Tate's Piano cencerto of Mozart.   Yes, I'm
doing hacking, and it needs more.   However, I'm now enjoying
music from this USB audio device.☺

Please replace usb/usbaudio part by this, sorry.
