USB Permissions Write Access for Midi Controller #14

Open EricKilkenny opened 3 years ago

EricKilkenny commented 3 years ago

Hello! Loving this build. The only issue I've run into is that I can't seem to set the permissions for my midi controller. Any Midi controller I plugin will give me the warning: USB Permissions problem (or device error) your account needs write access to USB HID. I am really not sure how to fix this little problem. I appreciate the help.

Quick reply, maybe you have to add the user (pi?) to the ‘audio’ and ‘plugdev’ groups. Add your user by issuing the command below (as sudo)

usermod -a -G

Thanks, Dennis! Appreciate the help. Didn't seem to fix the issue for me. . Mixxx recognizes the device is there and it can use the audio side of the device and under midi devices, it recognizes it - I just can't enable it. And then in the terminal, there's a bunch of error/warning notes about USB permissions and ALSA Lib.

Hi @EricKilkenny I also have these warnings in the logs but my HID and MIDI controllers work. It may be worth going to the Mixxx forums. If @dennisdebel's info is correct I will add that to the image.

@dennisdebel did you have to do that with this image? @EricKilkenny what controller are you using?

dennisdebel commented 3 years ago

I cant recall i had to do this

@fayaaz I tried several different controllers and it was all the same issue. An APC40, Traktor Kontrol Z1, Akai MPD 24. I was using Mixxx on raspberry pi before with no midi controller issues. I only ran into this issue with this build. thanks @dennisdebel for the help. I'll head to the Mixxx forums and see if they can help me understand the issue.

fayaaz commented 3 years ago

@EricKilkenny does seem like a problem with this build then. What desktop environment were you using to run Mixxx on the rpi before?

EricKilkenny commented 3 years ago

@fayaaz I was just running good old Raspbian OS. I was doing my radio show off of that for an entire year and it worked great. However, I'd rather use your build. It's nicer than what is available via debian.

fayaaz commented 3 years ago

@EricKilkenny this is a very stripped down version of Raspbian OS with a few modifications to run irqthreads kernel parameter, use i3 etc. Ideally it should run the same but with realtime performance tweaks! The only thing I can think of is that the image here run devmon as part of i3 to deal with plugging USB sticks but it shouldn't make a difference. I have a Korg Kaoss DJ controller that is working with this image so it is strange indeed.

fayaaz commented 3 years ago

@EricKilkenny the Traktor Kontrol Z1 is a HID controller according to: https://github.com/mixxxdj/mixxx/wiki/native_instruments_traktor_kontrol_z1

I have added the udev rules as I have a S4Mk2 and it should work with this image! Make sure you are picking the HID controller instead of the midi one (on the S4Mk2 the MIDI is for the midi thru on the back).

Hello! I have same type of problem here! with the mixxx-pi build im unable to get my Pioneer SB3 working, It recognizes it as a HID controller, not MIDI. Works normally on Rasbian OS and Mixxx 2.2

That is very odd - I see no reason why that controller would stop working in 2.3 under my image. I can't remember if aplaymidi is installed on the image (if not sudo apt-get install alsa-utils) could you run aplaymidi -l and see if the SB3 is listed?

djnsjns commented 3 years ago

alsa-utils are installed and up-to-date and the DDJ is listed as a DDJ-SB3 MIDI 1. I'm new to this stuff so i don't know how to troubleshoot this any further.
