[alsa-devel] USB Quirks for Boss JS-8
Hi, I'm looking at developing a quirk for the Boss JS-8. The lsusb is as follows: Bus 001 Device 003: ID 0582:0109 Roland Corp.

Does this mean I need to ignore the (non-existant) lower interfaces?

Does this quirk help anything? I'm just asking because looking at the descriptors,it's not clear whether this device does comply to any standard interfaces at all. Could be the vendor just hides the compliancy, but they might have implemented a proprietary protocol as well. Daniel

It's supposed to be a 2-in/2-out audio interface. At least that's what it shows up with on Windows. The Windows driver README contains the following: "Of the total audio input/output channels provided by the JS-8, there are 2 INs and 2 OUTs [WAVE OUT Devices] OUT (JS-8) [WAVE IN Devices] IN (JS-8) [ASIO device] When using the JS-8 with an ASIO-compatible application such as Cubase, select "JS-8" as the ASIO setting for your application. * To prevent an audio feedback loop or double monitoring, make settings on your application to turn monitoring off or use ASIO Direct Monitoring. * The JS-8 does not actually support ASIO Direct Monitoring. For greater ease of use, support is simulated. * When using the JS-8 with ASIO, we recommend that you set your application so that it does not use the Microsoft GS Wavetable SW Synth. (In order to decrease the load, and for convenience when changing Audio Buffer Size of the driver.)" It could well be proprietary, but it's a Roland device and my understanding is it's not uncommon for Roland to hide standard usb-audio interfaces behind non- standard identifiers. I have USB Device Monitoring Studio on my Windows laptop so I can dig further, although I'm not entirely sure what I should be looking for. Cheers, -- Keith A. Milner

Certainly not; endpoint numbers are not interface numbers. Try with audio interfaces 0 and 1 and MIDI interface 2.

Many Roland devices work this way. (And I'd expect any USB audio developer to instantly recognize descriptors like "0b 24 02 01 02 04 18 01 44 ac 00". ;-) Regards, Clemens

Excellent. I will give this a try and see how it goes. I wasn't actually aware it had MIDI. I guess this may be used for some sort of control function, or maybe it's in the hardware but not supported in the devices firmware.

I have to profess my ignorance here. Thanks for you help. I will report back on how I get on. -- Keith A. Milner

Well, that was remarkably easy! I tried with these settings and it seems to work very well. At first try (using Ardour with Jack) both input and output work. Many thanks for your help on this. I'll test it a bit more and then work out out to submit as a patch. Cheers, -- Keith A. Milner
Hi, I am not able to hear any sounds in my JS-8 connected to my Fedora 17, The device is recognised by the system, but no sound can be played, I've tried with jack too, but no luck, Can you please tell me if jackd needs any special parameters in order to run with JS-8? Best regards, Adolfo

You might have hit a bug here that I introduced during a refactoring of the driver. Unfortunately, I can't reproduce that with any of the multiple USB audio devices I have at hand, but someone from the alsa-user ML offered me to send over his device that also show this problem, so I can have a look. Stay tuned please, and my apologies for the trouble. Meanwhile, you could check whether any of the kernels between 2.6.39 -> 3.4 works for you - they all have the quirk for the JS-8. Thanks, Daniel
Thanks for your response, If I can help you in testing the fix please let me know Regards, Adolfo 2012/10/16 Daniel Mack <zonque@gmail.com>

If it's any help, I'm running Linux Mint 13 with a 3.2.0-34 kernel and it's working for me. I do get the following in dmesg: [47696.764621] usb 1-6.2: new high-speed USB device number 12 using ehci_hcd [47696.858892] MIDIStreaming interface descriptor not found [47696.859099] init_device failed: MIDI 4-0: seq-midi This is due to an error in the original quirk I submitted which was brought to light when some changes were made to the USB driver. I will try to tidy it up sometime. Cheers, Keith
