problem with shiit dac modi (usb 1-1-port2: Cannot enable.)

Hello, I got a raspberry pi A and the latest version of volumio as of today (1.55)
I got one wifi stick that works fine on both ports but my shiit dac doesnt,
I have tried without the wifistick as well, and tested both usb ports.

I see this in dmesg,

usb 1-1-port2: Cannot enable. Maybe the USB cable is bad?
[ 4.401619] udevd[158]: starting version 175
[ 5.146746] usb 1-1-port2: Cannot enable. Maybe the USB cable is bad?
[ 6.046686] usb 1-1-port2: Cannot enable. Maybe the USB cable is bad?
[ 6.926549] usb 1-1-port2: Cannot enable. Maybe the USB cable is bad?
[ 6.935213] usb 1-1-port2: unable to enumerate USB device

the dac is tested with the very same cable on a windows computer and it works nice.
Just bought a new psu to the pi to rule that out but no help :frowning:

edit: also bought a brand new cable which didnt help.
edit2: the light on the dac works btw, so it gets power atleast.
Any tips?

Best regards

If you tried both solutions, then I don’t have any more clue…
My last bet would be setting USB to High current…

nano /boot/config.txt
and add

max_usb_current=1

It works on + models, so don’t know whether yours is supported. Also, use with caution, as I remember to see some warning on the usage of max current option…

Let me know

Tried that, didnt help.

It worked before with raspify 1.0, which im trying to install again, but cant get it to install for some reason… :slight_smile:

Try to enable the C-media fix…

that option is greyed out, cant do anything with it

just got back from the store with a brand new rpi2, same problem… tested the dac on yet another laptop and it works there too.
Any others have problems with shiit dac?

dwc_otg.speed=1 makes it appear in dmesg and aplay, but this forces usb 1.1 on the entire machine right?
im afraid network speed will be too bad.

You can try, is not gonna be too bad…
Just don’t expect to get your FLAC files from NAS…
One last try could be trting to update alsa… Do you need help on that?

I only use volumio as a upnprenderer/airplay target, and I do use flac only for upnp so I guess it might be a problem…
I dont see why upgrading alsa would help?

without that usb 1.1 command It doesnt even show up on lsusb.
