Driver: EMU USB 0404 driver development

[Klaus Schulz]

Hi folks.

I learned that EMU handed over specs related to the EMU 0202/0404 USB to
you guys some time ago.

http://ubuntuforums.org/showpost.php?p=4892734&postcount=157

Is anybody assigned to the task?

Cheers

Doesn't it already sort of work with limited functionality?

Yep.  But rather by coincidence ( at least a quirk to recognize the card and
a small routine (usbaudio.c) to handle the samples properly has been
implemented).

First you need to upgrade the  firmware via Windows - which is a must. After
that the card defaults to 44,1/16 after power up.
This is the reason why 44.1/16 playback works.

What's missing, is the complete control of the card modes, register settings
etc.

If the registers are known, which I assume, according to EMU statement, it
shouldn't be a big deal to get it working.

Now it would be interesting to know who sits on these information. I'd be
happy to get in touch with him to support the design process.

Cheers

James Courtier-Dutton has been making drivers for E-mu PCI cards, so
there is a chance that he might be the guy who got the datasheets or
know who did. Maybe you should ask him.

Hi Vedran.

How can I get in touch with him?
I looked up responsibilities for EMU10k1. Takashi and Jaroslav seem to be in
charge for that EMU product.

I have no datasheet, at least...

James Courtier-Dutton has the E-MU USB specs. Quoting
<https://bugtrack.alsa-project.org/wiki/wikka.php?wakka=emu>:

"EMU have also now sent me a datasheet for the EMU USB sound cards. I
just need the time to play with them a bit to get them working.
Please feel free to send me donations to my paypal account: James at
superbug dot co dot uk
The support for the EMU USB cards has started, and basic support is now
in the latest alsa hg. It only supports 48000 rate, but all the in/outs
should work. Still TODO: Control of extension units that are used for
setting the rate,spdif options etc."

That's the last update, from 2007-10-07. Many people have offered help...

BTW, I guess the 48000Hz rate refers to the hardware's default sample
rate. The E-MU Tracker Pre (and recent 0202/0404 USB firmware) actually
defaults to 44100Hz, so it seems only that rate works with ALSA usb-audio.

Has anyone heard from James recently? I CC'ed him on a question about
jack latency on E-mu PCI cards recently, but he never replied. Wonder
if he wasn't interested in replying or he is not reachable at all.

Re: Driver: EMU USB 0404 driver development

[Klaus Schulz]

Hi folks.

I'd like to have a look at the subject of developing a driver for the EMU
0404 USB,
(at least to see to see how far I can get by myself)

I contacted EMU support via Internet - they didn't even answer my question.

I am wondering if there is a special channel of how to get in touch with
the EMU guys to get the specs and discussing the NDA subject?
