USB peripherals

[codebreaker]

Hi,

I am running phosh on manjaro on my pinephone. When I connect the usb docking bar, I am then able to connect, for example, a usb sound card to the dock, and it shows up in sound settings. Without the dock, plugging anything into the usb C port on the phone turns the screen off. This includes a simple usb-c to usb-a female cable.

How can I use the usb port for peripherals? Is it possible to use the pogo pins for usb peripherals?

Thanks.

I just tried plugging in a MicroSD card in a reader via a USB-C - USB-A adapter. Manjaro Phosh, works fine.

Output from dmesg.

Have you updated the anx7688 firmware? https://wiki.pine64.org/index.php/PinePh...X_firmware
Also do you have a Braveheart or Ubports edition? Those have a VCONN problem. https://wiki.pine64.org/wiki/PinePhone_1...rdware_Fix

This might be a problem of not having enough power to supply the attached device. I noticed that when I use the docking bar with hdmi, a wireless mouse and a wired keyboard connected to it, the screen turns off, it doesn't work. If I either remove the keyboard or the mouse or if I power the docking bar via the USB-C port, everything works. So maybe your sound card draws too much power for the phone itself. Unless you didn't have power going into the docking bar, then it must be something else.

8bit: Thanks for the suggestions. I tried updating the anx7688 firmware as described in the link, no change. I have not tried solving the VCONN problem, as that requires desoldering a tiny solder joint. That will be my last resort.

kqlnut: Thanks. I actually hadn't thought of that, good idea. But the fact that just a usb cable with nothing attached turns the screen off makes me think its not that. But I will be mindful of power consumption going forward.

Can the pogo pins be utilized as a usb input?

Today is the last day to order a replacement 3GB board at a discount for Braveheart/Ubports.
