Linux/AM3358: VBUS error

What Linux version are you using?

I'm using linux yocto for it.

What VERSION?

I forget the version, but I compile it myself and it's kernel 4.xx, I put extra 147uF capacitor on VBUS, and now it seems stable, I'll give a test.

It's not stable,
I got it again :

====

When does the failure in the log above happen? during device insertion or running application after the device is enumerated?
Please provide the kernel version, 'uname -a' commend will tell it.
Where on the VBUS line did you put the CAP? It should be close to the receptacle.
You use the 5V power jack to power the Beaglebone Black board, not usb powered, right?
What usb device you used to trigger the failure?

It happened during booting after reading the kernel,

Kernel version :

uname -a
Linux beaglebone 4.10.9-yocto-standard #19 PREEMPT Sun Jul 23 13:39:35 AWST 2017 armv7l armv7l armv7l GNU/Linux

I put the cap on USB port, solder on terminal + and Gnd.

Yes I do use 5V jack,

It's USB Audio device that trigerring the error and I attach a Creative Speaker as well with it, may be that's another issue causing over current ?

The speaker itself needs 5V 500mA, probably I need an independent power supply for it ?

Thanks

The Beaglebone board is a community board and I, as a sw guy, not sure if its PMIC design can supply the full 500mA on VBUS line. So if the USB speaker has an external power input, it is better to provide that power supply and not rely on the power from the USB port.

Now, I'm using a speaker at all, only USB sound device connected and here's the boot message :

with external power supply for speaker, it can run now but I got "hummm....." noise on my speaker..

I connect USB speaker to VDD_5V on Beaglebone black and it happens :

and the output of my USB sound device is connected to the speaker.

I use 7805 as my 5V source, is it not enough ?

Riko,

I think the problem you are facing is more like hw/board related, please ask your queries to the Beagleboard community.

It's stable when I don't use my active speaker, currently I try with headphone and it works ok,

Does that USB sound device have an amplifier already, causing missed impedance match ? and triggering over current ?

Both of your speaker and headphone use USB connection, and the headphone works fine but the speaker gives VBUS error, right?
You connect the speaker or headphone one at a time, didn't use a USB hub, right?

What do you mean by "USB sound device"? the USB host port on AM3358?

That's my USB audio device :

==========

It's not stable, I have put a speaker power outside USB, I used VDD_5V, but it's still intermmitent.

I have no clue why ??

I have to guess on what you are doing based on multiple times reading this thread:

Your "USB Audio Device", which connects to Beaglebone Black USB host port, has an audio output port, where you connect your speakers or headset. With the headset, the system works fine; connecting the speaker causes USB VBUS error. Even adding a 147uF cap on vbus line doesn't solve the issue. Is it correct?

If so, it sounds like an issue on the setup with the "USB Audio Device" and the speaker. Please note that the USB2.0 Spec requires any usb device should have no more than 10uF cap on the upstream port vbus line, and doesn't drain more than 500mA current after enumeration and no more than 100mA before enumeration. You have to ensure your system does meet the requirement.

Yes I tried with 147uF for rectifying over current issue, but doesn't help.

Now, I tried with 10uF without USB audio plug in and USB speaker is not connected,

It's still got :

Any clues ?

I don't understand what you are doing. If no USB audio device or USB speaker plugged in, what else you connected to the AM335x USB host port? Please note that the 10uF I mentioned before is the requirement for the USB device upstream port, not host port. The host port requires minimum 120uF.

No idea.

To remove any variables, please download the Processor SDK prebuilt from one of the links below, which includes both kernel image and filesystem, and test your scenarios, don't use the kernel image you built.

What went wrong with it ??

Which Processor SDK/Kernel do you use? Please test with the prebuilt binaries in the package in the download link I provided above, and don't plug in any usb device on the usb port.
