USB Hub issues with Audio and Usb

[akstein]

First of all congrats for creating such a great community. I wouldn't be able to make it this far without looking at the videos, guides, recommendations, suggestions etc... I decided to post my issue because I haven't been able to make it work just by reading other people posts. I feel I am close to completion but I don't know why the sound and the USB don't work. I am trying to keep it as simple as possible so I only need the sound to come out into an speaker. I don't need the audio jack (taking this out of the equation).

I believe the problems is with the USB Hub. The extra USB is not working either. Whenever I try to connect anything to it... it's not recognising it like a USB keyboard or mouse+keyboard dongle.

If anyone has experience with something similar and can put me in the right direction please do so. I am going to try to give as much information as possible by showing pictures and logs

The picture below shows the current situation of the build (a bit chaotic sorry!) hope you can see the wires and the components I am using.

I believe there should be another audio module showing but it does not appear even though in the logs above it says "sbcore: registered new interface driver snd-usb-audio".

I hope you can help me with this issues. Let me know if you need further information

Thanks in advance

A few things to check:

Is your USB hub getting power? Simple test is whether the blue LED comes on (i use the same hubs). You can also use a multimeter.

If not, start there.

If so, re check data lines as this is not showing up on your lsusb output check.

Are you powering your screen from the USB hub? I dont recommend doing that. Power from the powerboost / equivalent or use a power hub (like Helders).

Does your soundcard get power? Again i use the same ones and they have red LER power indicators.

Not 100 percent on your audio wiring either. You've not wired one of the pads on the USB card.

Hi @Lphillimore,

Thanks for the reply. Yes the USB Hub gets power and the blue LED flashes. I thought the USB Hub was one of the options listed in the lsusb output. In the dmsg output it identifies 4 USB ports after having changed /boot/cmdline.txt and adding the speed=1. Otherwise it was only identifying USB one port.

I am using the USB Hub to power up most of the components in my build. The powerboost powers the USB Hub and from there I power everything else (this might be the cause root of my problems). Is there any power hub you recommend using and that it can be delivered over to the UK?

The sound card works intermittently. It gets 5v from the USB Hub although the audio gets 1.4v and the mic 2.44v, not sure why the difference in the voltage. The weird thing is the way I have wired it up with the potentiometer wheel then the audio gets no voltage. I am not 100% sure how to rewire the USB sound card to the speaker and the potentiomenter wheel . Help is always appreciate it.

I have already ordered a new USB sound card because sometimes the red LED indicators comes up but right now it doesn't. Might be because of the power distribution, not sure.

Please find below some pictures to illustrate the above

The picture below shows monitor, powerboost and USB Hub getting power blue LEDs (the sound card's red LED is not appearing but I had it flashing yesterday)

The picture below is a close look of the powerboost. I have noticed that there are some pads not used. Could I use the available pads to power up the monitor from there. This way the power boost will be powering the monitor and the USB Hub - not sure if these will make any difference.

Thanks for helping

[Lphillimore]

Looks like your hub is fine yes and agree it's listed there. That's a good start!

I definitely would not power everything through the hub.

See additional pinouts on 1000c:

Or, you could use one of Helders breakout boards.

http://market.sudomod.com/power-strip-pcb/

Ref your pics, you can indeed use those pins to power the screen.

What I do however is use the pins you've used for your hub to power the breakout board.

Everything else is then powered from this board.

For example:

- USB Hub
- USB Sound (if used)
- USB port (female)
- Teensy / Leonardo (if used) etc...

I have a fair few breakout boards spare. Happy to send you one if you'd like as ordering them can take some time to ship and they are also made per order.

Regards

[akstein]

Yes it looks like using the breakout board is a more reliable solution. I am more than happy to use one if you don't mind sending it over.

Appreciate your help @Lphillimore

No problem, message me your address and ill send one tomorrow

Hello guys,

I have almost the same setup.
I see the USB hub and USB audio card in the lsusb output. But no sound.
Is there a parameter to change in any recalbox config files to activate the sound ?

Thx.

[akstein]

Wired the breakthrough power hub to power up all the different components; screen, raspberry pi zero w, external USB and USB sound card. The original issue raised in the post is still persisting and I am not sure what to do to solve the issue.

The USB sound card displays the red LED consistently - that's progress from last time - although it is not recognised when doing lsusb or cat /proc/asound/modules.

see the outputs:

I am also a bit concerned it is only identifying 1 USB port and audio sound cart is not being added I believe

I have a very similar build I'm currently working on.
I'm using the same USB hub and want to connect a teensy lc and usb audio to it.
For powering the USB hub I'm using a power strip as mentioned here already.

I had the teensy connected which was working but I'm afraid I destroyed the USB hub recently as I can't get it to power on.
I'm now waiting for my new USB hub (same type).
Will keep you updated here.

Recheck your data wires on the pi. Make sure they are not bridged. This also goes for the small circular recesses to either side. This is your source / gateway of all data.

From there, again check the input to your USB hub. Ensure data wires are soldered without shorting on anything.

USB Soundcard can be wired directly to the USB hub. No need for breakout board on this one.

Any new pics?
