Kernel 5.10 strange behaviour (Pixel 6a)

[iodn]

I have been using usb-gadget tool for a while on my Xiaomi 11 Lite (Kernel 4.14) and no problem.
But I recently purchased a Pixel 6a (kernel 5.10), /dev/hidg0 and /dev/hidg1 are present and enabled.

The strange thing is that when I execute a command on /dev/hidg0
e.g.

echo h i | ./hid-gadget /dev/hidg0 keyboard

The output is reflected on the mobile phone itself instead of the device that should be connected (PC or another device ..).

For /dev/hidg1 the output is "Success" but nothing happen, seems my PC does not recognize my phone as an HID device, unlike my other Xiaomi phone running under kernel 4.14

Do you have any idea why it behaves this way?

Hi,

I don't have any phone with kernel 5.1 (yet), so I can't test it. I might try this on a Pi. I don't have any clue - sorry.
What is the value of getprop sys.usb.controller ?
What ROM are you using? Stock? And which release exactly? Then I can check if there is something new in the kernel.

[iodn]

Okok I see, no problem.

What is the value of getprop sys.usb.controller ?

bluejay:/ # getprop sys.usb.controller
dummy_udc.0

What ROM are you using? Stock? And which release exactly? Then I can check if there is something new in the kernel.

Well I started with the official Google rom from this month (Jan. 2023, https://support.google.com/pixelphone/thread/195623748/google-pixel-update-january-2023?hl=en)

Then I realized that usb-gadget tool didn't work, so I installed a custom rom (GrapheneOS) (https://grapheneos.org/releases#bluejay-stable) thinking that I might have better luck but the result was the same.

I've also thought about downgrading the kernel to try, but I'm still not sure how to do this on Android and I need to do more research.

[tejado]

What is the value of getprop sys.usb.controller ?

bluejay:/ # getprop sys.usb.controller
dummy_udc.0

This is a dummy USB controller and not the actual one. I guess this is the issue.
Can you look whats inside the directory /sys/class/udc and as well activate ADB and see what value the default USB gadget has, e.g. by executing the command 'cat /config/usb_gadget/*/UDC' ?

[iodn]

bluejay:/ # ls /sys/class/udc/
11110000.dwc3  dummy_udc.0
bluejay:/ # cat /sys/class/udc/dummy_udc.0/uevent
USB_UDC_NAME=dummy_udc
bluejay:/ # cat /config/usb_gadget/*/UDC
11110000.dwc3

[tejado]

bluejay:/ # ls /sys/class/udc/
11110000.dwc3  dummy_udc.0
bluejay:/ # cat /sys/class/udc/dummy_udc.0/uevent
USB_UDC_NAME=dummy_udc
bluejay:/ # cat /config/usb_gadget/*/UDC
11110000.dwc3

Great, then use USB Gadget tool as usual. But if you want to activate the respective gadget, e.g. MouseKeyboard, please test the following:

echo "" > /config/usb_gadget/*/UDC
echo 11110000.dwc3 > /config/usb_gadget/MouseKeyboard/UDC

So I guess I need to adjust the controller detection in USB Gadget tool.

[iodn]

Hmm, every time I try to overwrite the /config/usb_gadget/MouseKeyboard/UDC file it comes back to the initial value dummy_udc.0

bluejay:/ # vim /config/usb_gadget/MouseKeyboard/UDC                                                                  
bluejay:/ # cat /config/usb_gadget/MouseKeyboard/UDC                                                                  
dummy_udc.0
bluejay:/ # echo 11110000.dwc3 > /config/usb_gadget/MouseKeyboard/UDC                                                 
1|bluejay:/ # cat /config/usb_gadget/MouseKeyboard/UDC                                                                
dummy_udc.0

[tejado]

What about the other gadget, the default one? Does it still has 11110000.dwc3 in it? Can you also paste the kernel log (dmesg) if you are writing to UDC? Thanks.
Please paste these logs on pastebin - not directly here as it will otherwise too much text.

The file was too big for Pastebin (You have exceeded the maximum size of 512 kilobytes per Paste.), I uploaded it on controlc.com

[tejado]

Thank you - can't see anything in the log which relates to this.
I will need to investigate - unfortunately, I don't have any device which this kernel.

If you can find out why this is happeing, it would be great.

[iodn]

Update, when I setprop ro.boot.usbcontroller and sys.usb.controller it seems to work and could overwrite the /config/usb_gadget/MouseKeyboard/UDC file but my computer still doesn't recognize the mobile phone as HID device and nothing happen when I try to execute some commands.

bluejay:/ # cat /config/usb_gadget/MouseKeyboard/UDC
dummy_udc.0
bluejay:/ # setprop ro.boot.usbcontroller 11110000.dwc3
bluejay:/ # setprop sys.usb.controller 11110000.dwc3
bluejay:/ # ##Re-enable MouseKeyboard gadget from the app
bluejay:/ # cat /config/usb_gadget/MouseKeyboard/UDC
11110000.dwc3

Another strange fact, if I load hid.keyboard directly from the gadget path by default /config/usb_gadget/g1/ it works halfway. For some reasons my windows machine still doesn't recognize the mobile phone as HID device but when I plugged it into my Linux box the HID payload I coded kind of work but all the characters are in uppercase and the special characters like slash / are replaced by interrogation marks ?.

[tejado]

Okay, interessting. Thanks a lot for the information. I will hopefully get a device with such a Kernel in the next days, so I can look more into that.

Under Windows, do you get the same error in the Device Manager as the following issue? #42

If you are using hid-gadget tool, I can't help you there as I'm not using it. Try Authorizer.

Oh so cool, that's good to hear then!

Under Windows, do you get the same error in the Device Manager as the following issue? #42

No, there is no error message, the phone is just not recognized at all by the computer when /usb_gadget/MouseKeyboard is enable.

If you are using hid-gadget tool, I can't help you there as I'm not using it. Try Authorizer.

Yes, I know but my test script works perfectly on two other phones, so it should also work in theory with the Pixel 6. But thanks for the info, I'll try Authorizer.

[SF73]

Hey, any news concerning this issue?
So far, it seems possible to edit the default gadget (g1) but not create one from scratch.

[tejado]

Unfortunately not. I thought I'm going for the Pixel 7a instead of 6a. So will get it in the next days and then have a look into that issue.

[MikeDev101]

Having a similar issue on the Pixel 6 (oriole). I edited the props as mentioned in #43 (comment) but I couldn't get any devices to detect USB HID mode.

EvolutionX 7.9.7 (Pinakbet) for Oriole
