[alsa-devel] AKAI EIE PRO
Dont know if its ok to ask a question here so please let me know if its not ok then i wont ask again ;)
i just bought an external usb AKAI EIE PRO sound card, is there any future plans to implement it in Alsa?

Please send the output of 'lsusb -v' with this device connected. In best case, we only have to add a quirk table entry.

Hi Daniel, if that can help, we had an user on http://www.linuxmao.org with an EIE PRO. Here you have his lsusb -v :

According to the tech specs, this should be a USB hub, but it isn't. Or is this just one of the sub-devices? What does 'lsusb -t' say, and does Linux see something like a mouse or mass storage device when connected to one of the hub ports?
Assuming that's just the audio part ...
Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x02 EP 2 OUT bmAttributes 5 Transfer Type Isochronous Synch Type Asynchronous Usage Type Data wMaxPacketSize 0x009c 1x 156 bytes bInterval 1 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x83 EP 3 IN bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0200 1x 512 bytes bInterval 4 Endpoint Descriptor: bLength 7 bDescriptorType 5 bEndpointAddress 0x04 EP 4 OUT bmAttributes 2 Transfer Type Bulk Synch Type None Usage Type Data wMaxPacketSize 0x0200 1x 512 bytes bInterval 4
So at least, they're not trying to hide class-specific endpoint descriptors here, which what I've been hoping for.
I guess someone has to trace the traffic spoken to this device by the Windows driver. I take it this thing doesn't work on OS X with a 3rd party driver?
Daniel
Daniel, I've been asking to the interface owners on our website if they can provide the information you requested I'll keep you updated if I have answers there.
Re: driver on OSX, given http://www.akaipro.com/product/eiepro#downloads , I think you're right.
Best, Olivier
PS: (apologise for the message sent twice Daniel)

I have analyzed the protocol more than a half year ago. I even tried to create a linux driver around it but had to stop due to lack of time. I hope I can continue working on it in November again.
I have published what I have done so far to github few seconds ago if anyone wants to have a look or perhaps contribute.
https://github.com/mmm444/eie-pro-linux
I can write more text about the protocol if someone is interested.
Regards,
Michal

Hi Daniel and all,
An linuxmao.org user gave answers to these questions today. Here you go:

Hope that can help in any way. If you would need some more information, please let me know.

Hi to everyone, I've been asking the user to test the USB hub thing. He did and it worked as usual. He tried twice, once with a mouse and the other with an external hard-drive.
Hope that helps. Olivier
